If you fly drones or race RC cars, you know the worst sound is a 2S LiPo battery that won’t take a charge. The real fix is a charger that balances each cell properly and handles 7.4V packs without fuss. This guide cuts through the jargon to show which 2S battery charger earns its spot on your bench, based on specs and owner reports.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The chargers below all support 2S (7.4V) LiPo packs with balance capability, but they split into clear camps: multi-port workhorses, powerful single-bay units, and budget-friendly entry points. Read on for the best 2s battery charger options that fit your fleet, your bench space, and your wallet.
Our Picks at a Glance
How To Choose The Best 2S Battery Charger
Before you buy a charger for 2S LiPo packs, think about how many batteries you fly per session, what connectors your packs use, and if you want to watch over the process. A 2S pack is just two cells wired together at 7.4V, and the charger’s job is to fill both cells evenly so neither one gets overworked.
Ports and Amperage: Match Your Fleet
The biggest fork in the road is port count. A single-port charger is fine if you fly one pack and wait, but the moment you have a rotation of batteries, you will want a 4-port unit that can top off the whole fleet overnight. Amperage (measured in A) sets the ceiling for how fast each port can work—a 1.5A charger is gentle and slow, while a 10A unit can hammer a big pack in under an hour.
Balance Port vs. Main Lead: Know Your Connector
Some chargers only talk to the small white balance plug (the JST-XH lead), which is great because it means the same charger works with XT30, T-plug, or bare-wire packs. Others charge through the main power lead and balance through a separate port. As long as the charger has a balance mode, you get the safer charge—the question is whether your battery’s plug fits the included cables.
Safety and Storage: Protect Your Investment
A good 2S charger does more than fill cells. Look for storage mode, which automatically drains or tops up a pack to a safe long-term voltage, and temperature monitoring that shuts the unit down if things get hot. These features are what keep a charger from turning a battery into a fire hazard.

In‑Depth Reviews
1. Venom Power Pro Duo LiPo Battery Charger
Our pick — over 4.5★ from 850+ verified ratings; the strongest balance of quality and price.
The dual-80W workhorse that powers two packs at once without breaking a sweat.
The standout feature here is the twin charging circuits. You get two ports, each with its own 80W of power, for a combined 160W—so a 2S pack on one side and a 6S pack on the other charge simultaneously without slowing each other down. Buyers report a 3500mAh 2S pack reaching full charge in 58 minutes, a fast balance-charge time.
Beyond raw speed, the Venom is a feature vault. It handles LiPo, LiHV, Li-Ion, LiFe, NiMH, NiCD, and Pb chemistries, and ships with eight different charging leads (alligator, Deans, EC3, EC5, JST, RX, Tamiya, XT60) so you rarely need an adapter. The internal temperature monitor cuts the charge automatically at your set limit, a comfort when you are pushing high-capacity packs.
The catch is durability feedback: A few owners mention the unit failing after about 60 days of heavy use., while the vast majority praise its ease of use and battery-preserving behavior. It runs on standard 120V AC house current, and the lightweight 2lb frame with a built-in handle makes it easy to carry to the track.
Dual-Bay Muscle
- Two independent 80W circuits charge 2 packs at once
- 8 pre-wired connectors cover nearly every RC plug
- Temperature monitoring auto-stops the charge
- Easy to use with fast, consistent results
Buyer Watch-Outs
- Some units reportedly fail after about 60 days
- Needs extra cords for certain 6S setups
- QS8 connectors on high-power packs require an adapter
Reach for this if: you run multiple RC cars or drones and want to charge two different battery types side-by-side at full speed.
Look elsewhere if: you need a charger specifically for 1S micro packs; this unit shines from 2S upward.
2. VIFLY ToothStor 4-Port 2S LiPo Balance Charger
The 2S-only specialist that fills four packs and stores them safely overnight.
If you exclusively fly 2S packs, this is the easiest tool on the list. The ToothStor has four completely independent charging channels, meaning you can balance-charge a 350mAh whoop pack and a 1500mAh cruiser at the same time—they don’t need to match in voltage or size. It charges purely through the balance port, so any 2S battery with a JST-XH2.54 lead works, whether it ends in XT30, T-plug, or bare wire.
The headline skill is storage mode. You can charge or discharge a pack down to a safe storage voltage, the #1 feature owners cite for extending battery life between sessions. The color LCD shows each cell’s voltage at a glance, and the memory function remembers your last current setting so you don’t reset it every power-on.
There is one honest limitation: 1.5A is the max rate, so big packs charge slowly—owners say it takes a while. The box also does not include a power supply; you need a 65W+ USB-C PD block, an XT60 source, or 12V DC. The subtle fan and heat sink keep it cool during the slow discharge cycle, a real plus for 2S health.
Fleet Manager
- 4 independent channels charge mismatched packs together
- Storage mode protects batteries between flights
- Per-cell voltage display on a color screen
- Compact, beginner-friendly design
Keep In Mind
- Slow 1.5A max charge rate
- No power supply included; needs 65W+ USB-C or DC
- Balance plugs can be tricky to remove
Perfect for: micro-drone pilots and 2S-only bashers who want to charge a whole fleet of packs overnight without babysitting them.
Think twice if: you fly 3S or larger packs; this unit is strictly 2S.
3. SKYRC B6Neo Balance Charger
A pocket-sized 10A charger that runs off your USB-C power bank in the field.
This is the one to grab when you want serious amperage without the desktop footprint. The B6Neo pushes a full 10A in DC mode (200W) and 5A over USB-C PD (80W), so it charges a 2S pack fast whether you are at the bench or the park. Owners love pairing it with an Anker or Jackery power bank for field charging—the Type-C port makes it the most flexible travel charger here.
It is absurdly small at 82g, yet it packs an active balancer, storage mode, and a battery checker. The fan runs rarely and quietly; spec says 48 dB, which owners describe as a soft hum rather than a whine. The XT60 interface plus Type-C input covers modern setups, though some micro packs need a small adapter.
The trade-off is single-battery operation—it only charges one pack at a time, unlike the VIFLY’s four ports. A few owners also note the lack of a power cord in the box. But for a 1/24-scale racer charging 350-900mAh 2S packs, this is the balance of size, speed, and value.
Field-Ready Verdict: The B6Neo is the best answer to “I need a fast 2S charge away from a wall outlet.” Its 10A DC output beats the VIFLY’s 1.5A by 6.7x, but you trade multi-port convenience for that raw speed.
Grab this if: portability and USB-C flexibility matter more than charging multiple packs at once.
skip it if: you routinely need to charge four batteries before a race; the single-bay limit will bottleneck you.
4. Hiyiton 6A Balance Charger
A budget-priced iMax B6-style charger that arrives with every cable you need.
For beginners stepping into 2S and 3S RC, this is the classic first charger. It supports LiPo from 3.7V to 22.2V (1S-6S), plus Li-ion, LiFePO4, NiMH/NiCD, and SLA packs, and the box includes an AC power cable, DC cable, T-crocodile clip, XT60 plug, Deans charge cable, and Tamiya cable—so you aren’t hunting for adapters on day one.
The 6A current rating is plenty for most 2S packs, and owners specifically praise how it auto-detects LiPo and NiMH chemistries. A 2S charge finishes fast and runs cool, with audible alerts when done. The LCD shows your charging status and lets you store settings per battery, a feature usually found on pricier units.
The honest caveat: charging speed gets mixed reports—some say it is quick, others find it slow on larger packs. The built-in smart chip guards against over-current, over-discharge, over-voltage, and short-circuit, a strong safety net for new hobbyists. A 2-year warranty and 24/7 support back it up.
Bang-For-Buck Take: You get the full iMax B6 feature set—balance, fast charge, storage, cyclic—plus a 2-year warranty, at an entry-level outlay. It is the safest way to learn balance charging without risking a premium unit.
Best suited for: newcomers who want one box that charges their 2S, 3S, and NiMH packs with zero extra purchases.
Not ideal if: you demand the fastest possible charge times; the 6A ceiling is mid-pack.
5. Haisito B6V2 Balance Charger
The affordable workhorse that charges just about any hobby battery chemistry you own.
This B6V2-style charger is built for versatility. It covers LiPo, Li-ion, LiFePO4, NiMH, NiCd, SLA, and even LiHV packs from 1-6 cells, and it arrives with an octopus multi-charging harness, a battery protective bag, and a DC crocodile clip. The fireproof shell and UL specification add real confidence for a budget unit.
Owners consistently describe it as fast and easy to use., noting it handles both standard and balanced charging smoothly. The LCD is straightforward, and the discharge and balance features are genuinely useful for keeping packs healthy. It is compact enough to sit on a shelf without dominating the space.
The main entry point is the 6A / 80W ceiling—fine for 2S and 3S packs, but slow if you ever move up to big 6S batteries. A few owners mention needing a JST extension for certain balance plugs, which is a minor annoyance rather than a flaw. For the money, it is among the most complete low-cost kits around.
Universal Kit
- Charges 7 different battery chemistries
- Includes octopus harness and protective LiPo bag
- UL-specified fireproof shell
- Fast and easy operation
The Limits
- 80W max limits big 6S packs
- Some balance plugs need a JST extension
Choose this for: a mixed fleet of batteries where you want one reliable, safe charger that does everything adequately.
Pass if: you are charging massive high-voltage packs that demand 150W or more.
6. Tenergy TB6-B Balance Charger
The octopus-armed charger that connects to every plug your hobby room owns.
The Tenergy TB6-B earns its nickname “Techno-Octopus” with a single multi-charging harness that covers Tamiya, mini Tamiya, JST, HiTec, EC3, Deans, XT60, and bare leads. It also ships with a LiPo safety bag, a thoughtful extra for storing and charging your 2S packs. This is the charger to grab when your drawer is full of orphaned connectors.
Performance is strong: it balances a 3S or 4S LiPo in about 40 minutes at 1.5A, and Customers note it reviving old batteries that other chargers abandoned.. The 0.1-5.0A range and 1.2-22.2V support cover everything from tiny 2S whoop packs to larger 6S setups, and the 5 memory slots let you save your most-used profiles.
The learning curve is real—the menu is dense, and some owners find it less intuitive than SKYRC units. But the consensus is that once you learn it, it is reliable and runs cool with audible alerts. A 12-month warranty and 10-year EU spare part availability back it up.
Why It Wins Owners
- One harness fits 8 different connector types
- Included LiPo bag adds safety value
- 5 memory slots for saving profiles
- Revives older, deeply discharged packs
Honest Gripes
- Menu is not intuitive for beginners
- Instructions could be clearer
Ideal for: the hobbyist with a mixed bag of connectors who wants one harness to rule them all.
Skip if: you want a dead-simple one-button charger; this unit rewards a little menu patience.
7. HTRC C150 10A AC/DC Charger
A 150W dual-power charger with a 20-slot memory for serious multi-fleet racers.
If your charging needs outgrow the budget tier, the C150 steps up with 10A of current and 150W of power over AC or DC. It handles seven battery chemistries—LiPo, LiFe, Li-ion, LiHv, NiMH, NiCd, and Pb—with end-voltage control that experts can tweak from 3.85V to 4.3V per cell, a feature literally labeled “for expert only.”
The versatility extends to the included octopus harness with Tamiya, mini Tamiya, JST, T-plug, EC3, TRX, and Deans connectors. Owners running 2S-6S LiPo packs and 5000mAh NiMH batteries praise how it balances and stores packs consistently, staying cool even after four consecutive charges. It has run reliably for two years in some owner fleets.
The recurring caveat is durability of the harness—one owner reports the multi-charging cable breaking from wire pulling. Also, despite the claims, it cannot properly charge 1S batteries. The 20 memory slots, however, make it a genuine upgrade for racers who juggle multiple battery profiles.
Power User Verdict: The C150 matches the Venom’s 10A output and adds DC input flexibility, but you trade the Venom’s dual independent circuits for a single high-wattage channel.
Get this if: you need high amperage for big packs and want to store 20 battery profiles for different vehicles.
Avoid if: you fly 1S micro drones; the 1S support simply does not work despite the label.
8. SKYRC iMAX B6AC V2 Charger
The legendary B6AC, refined—quiet fans and genuine SKYRC build quality.
The iMAX B6AC V2 is the charger that every other budget unit tries to clone. This is the authentic SKYRC version, and it is noticeably quieter than the knockoffs—owners specifically note the fan noise is a non-issue compared to their other chargers. It runs off AC or DC power, pushing up to 6A and 50W, which is plenty for 2S packs.
It supports LiPo, LiFe, Li-ion, NiMH, NiCd, and Pb chemistries, making it a genuine all-rounder. One owner used a pair to rebuild a 2006 Honda Insight hybrid battery, highlighting its precise balance output. Discharging from full to storage level leaves it only slightly warm, never hot.
The catch is the input capacitor—a few reviewers point out a small arc or flash when plugging it in, since there is no soft-start or on/off switch. It is a quirk of the design, not a functional failure. At 632g with a 144mm x 135mm footprint, it is a bench staple that owners say pays for itself after balancing a couple of packs.
Why It’s A Legend
- Authentic SKYRC build, far quieter than clones
- AC and DC dual power input
- Supports 6 battery chemistries
- Holds voltage precisely for balance charging
Quirks To Expect
- Minor arc flash on plug-in, no on/off switch
- Instructions are not the clearest
Reach for this if: you want the confidence of a genuine SKYRC product that has been proven over a decade of hobby use.
Look elsewhere if: you need more than 50W of charge power; this classic tops out at 6A.
Understanding the Specs
Amperage and Wattage
Amperage (A) sets how fast current flows into your battery, and wattage (W) is the total power ceiling. A higher amp rating means a 2S pack fills up faster, but the charger also needs enough wattage to deliver it. The rule of thumb: a 6A / 80W charger is comfortable for 2S-3S packs, while a 10A / 200W unit opens the door to big 6S batteries.
Balance Charging and Storage Mode
Balance charging measures each cell in a 2S pack individually and tops them up evenly, preventing the puffy-battery problem. Storage mode is the same idea in reverse—it drains or fills a pack to a safe long-term voltage (usually around 3.8V per cell) so batteries stay healthy in the drawer between sessions. These two features are what separate a real hobby charger from a cheap wall wart.
