A 120C graphene pack that turns a stock RC car into something noticeably faster.

The discharge rating is where this pack earns its spot. At 120C (120 times its capacity in release speed), it pushes energy out three times faster than the Gens ace 40C pack above — a massive gap if your ESC (electronic speed controller, the part that regulates power to the motor) can handle the current. That extra current shows up as harder acceleration and stronger throttle punch — owners mention these packs “make your RC car go a quite a bit faster.” FPV drone pilots running Skylark m4-fpv250, Qav250, and Emax nighthawk 250 frames also find the 1500mAh capacity well-matched to a racing lap.

Each pack weighs 134 g and measures 2.68 x 1.36 x 1.08 inches. That’s noticeably heavier and larger than the 800mAh Gens ace option, but you’re getting nearly double the capacity in exchange. As one buyer put it after sticking with the brand for multiple vehicles: “I always turn to the Zeee brand when looking for new batteries.” Customer support drew praise too: one owner whose battery spent 10 days stuck in a tree during heavy rain said the company “took great care” of the situation.

Honest caveat: battery life draws mixed feedback. Some packs lose a cell and begin ballooning after extended use, though the pack that arrived with a defective cell was still described as a solid performer while it lasted. If you push these hard in high-draw applications, expect a shorter lifespan than a lower-rated pack. The XT60 connector is the standard for most modern RC cars and drones, so plug-in compatibility is rarely an issue.

A lightweight single pack that brings serious power to 450-class helis and sport planes.

At 126 g, this is the lightest 2200mAh pack in this lineup — 40 g lighter than the OVONIC shorty pack below — and it carries 2.8 times the capacity of the Gens ace 800mAh option in a package that weighs 50 g more. That ratio is why the OVONIC 2200mAh becomes the go-to choice for anyone flying P-51 warbirds, E-flite Valiant, Parkzone E4F Wildcat, or Align T-REX 450 helis. The Dean-style T connector (a common plug shape for RC batteries) is the standard plug for most sport airplanes and 450-class helis, so it seats without an adapter in those airframes.

Buyers running these in Trex450 helicopters report they “have held up well” after about 20 charge cycles each, with one noting several crash impacts hadn’t damaged the pack. The 50C discharge rate delivers a fast, responsive power curve across the full charge. Owners also praise a quick charge time and the soft-pack format that lets it fit into tighter fuselage compartments.

The catch is dimensional accuracy — it’s the most-mixed theme among owner feedback. Multiple buyers find the actual pack larger than they expected, and it won’t seat inside some battery compartments without overlap. It fits the 124017 v2 tray with a slight overlap but still secures snugly. Measure your compartment before ordering, especially if your model has a snug factory-fitted tray. The single-pack format (one battery, not two) is worth factoring in if you want a backup on the flight line.

Two reliable XT60 packs that cover the whole hobby with steady, predictable power.

For anyone new to LiPo batteries, this two-pack of CNHL 2200mAh 3S packs is the comfortable starting point. The 30C discharge rate (burst 60C) puts out predictable, even power that won’t overwhelm a stock ESC in a Slash, Rustler, or trail crawler. The XT60 connector is the most common plug on modern RC vehicles, so these plug into most models from the start. Each pack weighs 166 g and runs 4.17 inches in length, which fits standard chassis battery trays.

The run time is the standout. Owners describe driving an RC car “for almost 3 hours on one charge” at full throttle, and longer than stock batteries in the same model. The CNHL 2200mAh also charges fast — going from empty to full in just under 30 minutes when charged at 2C with a capable charger. Owners rank quality and lifespan high, describing these packs as durable through regular bashing sessions.

One honest note for true first-timers: these are not plug-and-play. You need a LiPo-specific balance charger with a digital display, a LiPo-safe charging bag, and a volt meter or tester to go with them. That’s normal for hobby-grade LiPo batteries, not a flaw in this product — but budget for the accessories before you order. If you already have a charger setup, these two packs cover more ground than a single higher-capacity pack.

The shorty-format pack built for tight battery trays that swallow standard 2200mAh packs.

Not every 2200mAh pack fits the same space, and this Zeee shorty proves it. At 2.95 x 1.34 x 1.04 inches and 137 g, it slides into compact trays on the Arrma Typhon Grom, SCX10III crawlers, and small planes where a standard-length 2200mAh pack would be too long. The 50C discharge rate and 2200mAh capacity deliver the same power and duration as larger packs — just in a smaller footprint.

Owner feedback on the shorty format is genuinely enthusiastic. “Excellent battery prefer the small size to fit in tight places in small planes,” one buyer writes, going on to say “Same power and duration” as larger packs. Another owner runs these in a Vanquish VRD and reports a single pack lasting around 3 hours. Owners rank quality and performance as this pack’s top traits, and it fits the SCX10III Coyote compartment with reliable run times.

The mixed part is battery life consistency. Some owners get several hours of use, while others see closer to 15 minutes of run time per charge. That spread usually depends on how hard you drive and whether you maintain the packs properly — this battery ships with a detailed safety manual and specific charge-rate guidance (0.5–1C, meaning charge at half to one times its capacity) that’s worth following if you want them to last. The XT60 plug (a common RC connector type) makes these plug-and-play on most modern RC vehicles.

The FPV racer’s pack: 1300mAh, 45C, and shipped at the right storage charge.

FPV pilots running QAV250, QAV180/210, ZMR250, or Vortex 285 frames already know the TATTU name. This 1300mAh 3S pack with a 45C discharge rate (45 times its capacity in release speed) is purpose-built for 250-class quadcopters — the balance between capacity for lap time and low weight for agility. The XT60 plug is the racing standard, so it drops straight into most mini-quad wiring harnesses. At 72 x 36 x 23 mm, it fits the tight frames those builds use.

Owners rate build quality the most-praised aspect by a wide margin, with performance a clear second. One buyer specifically highlights that the batteries arrive at “perfect storage charge,” which is a real advantage if you want to fly the moment the package lands. Owners also note the packs perform well in cold weather and endure many charge cycles even when handled imperfectly. For a 1300mAh pack, the capacity is within the acceptable range according to owner measurements.

There is one significant risk worth flagging: a minority of users report receiving a battery discharged to damaging levels. One owner received cells at 1.9V, 2.0V, and 2.1V, and after charging found one cell significantly weaker than the others. This is not typical, but it’s a real possibility when ordering LiPo packs shipped from any vendor. Check your cells with a volt meter the moment the pack arrives, and use the 60-day return window if anything looks off. Battery life also draws mixed feedback over the long term — some reviewers point out excellent longevity, others less so.

A shorty two-pack that wakes up 1/18 crawlers and mini trucks without eating up tray space.

Swapping out a stock 1800mAh battery for one of these 2200mAh OVONIC packs is a dramatic upgrade for a mini truck — buyers describe making their RC car “faster, more responsive” with a 35C (70C max) discharge rate (35 to 70 times its capacity in release speed) that provides strong acceleration. The shorty soft-pack format at 2.95 x 1.34 x 1.04 inches and 140 g fits 1/18 crawlers and Grom-line Traxxas trucks like the Mini XRT and Mini Maxx without forcing modifications.

Owners praise the two-pack format: two 2200mAh shorty packs give you a backup without hunting down another compatible battery. Owners also love the run time; one customer describes serious power output delivering about 12–15 minutes of intense speed per charge. Compatibility with multiple Traxxas Mini models is repeatedly confirmed. The included Deans-T connectors (a common RC plug type) are drop-in for anything running that plug type.

Two honest notes. First, these packs are heavy for their size at roughly 140 g — noticeable if you’re trying to keep a small truck light. Second, the charging cord is long, which makes it awkward to tuck inside a small RC body during use. Neither is a deal-breaker, but they’re worth knowing. The OVONIC dedicated charger is recommended by the manufacturer for safe charging, so factor that into your setup if you don’t already own one.

The OEM upgrade for HYPER GO trucks that turns a mild basher into a wheel-lifting monster.

The defining number here is compatibility: this pack is built specifically for HYPER GO’s H16 and HB16 series trucks and 1/14 and 1/16 scale models, with a parts number of 3S2000. That’s not a universal RC battery — it’s the official upgrade path for an existing HYPER GO owner. The included XT60-to-T-plug adapter and charging wires mean it connects to the truck’s existing wiring without hunting down extra accessories. Capacity is 2000mAh, discharge is 25C, and the pack weighs 150 g.

The upgrade payoff is real. Shoppers say the battery significantly extends run time over stock — one says it runs “close to 30 minutes on 70% charge,” and another describes it quadrupling run time. Speed is the third most-praised trait, with owners noting the trucks become noticeably faster. One long-term reviewer has been running his battery for a year and a half with no issues, reporting it “holds a charge well and works reliably.”

Fit is the honest weakness. It’s the most-discussed concern in owner feedback, and the pack measures 4.61 inches in length — noticeably longer than a stock pack. Some buyers report it doesn’t seat cleanly in the tray without a little reworking, though the charging port sits on a protruding wire so you can charge without removing the body. If you own a HYPER GO H16 or HB16 truck and want the manufacturer-matched upgrade, this is the right pick. If your model is any other brand, this isn’t the battery for you.

The long-run workhorse for large-scale planes and Traxxas trucks that can spare the weight.

With 5000mAh on tap, this HRB pack is the capacity champion of the lineup — holding more than twice the charge of a 2200mAh pack and more than six times the charge of the 800mAh Gens ace option. That translates to genuinely long sessions: customers note about an hour of run time on a full charge, or 2-3 bashing runs per charge. The 50C discharge rate gives it enough punch for aggressive driving. It comes with a Traxxas-style plug (TR), so it drops into most Traxxas trucks without an adapter.

Weight is the cost. At 376 g, this is the heaviest pack here — nearly three times the mass of the OVONIC 2200mAh pack. Large-scale planes and 1/10 scale trucks handle the extra weight fine, but lightweight airframes won’t. Reviewers point out it fits the Slash 4×4 (regular and LCG), Rustler 4×4, 2WD Slash, and 4Tec 2.0 chassis.

Fitment is where you need to pay attention. Multiple owners note the pack is longer than usual — one reports it’s “slightly too big for the TRX-4 Sport compartment” and puts pressure on the wires, noting it needs to be about 1/16 inch shorter. Others report fitment issues with non-Traxxas chassis. Measure your battery tray carefully before committing. If it fits, though, the HRB is described as a “workhorse” that lasts 3+ sessions of 45–60 minutes each.
