Three 3S picks tested across trainer planes, RC cars, and FPV — specs compared, trade-offs named, and a budget option that doesn't compromise where it matters.
For most beginner RC plane pilots: Spektrum 2200mAh 3S 30C — matches the voltage, capacity, and connector standard of the most popular trainer aircraft, 30C is more than enough for a trainer motor's current draw. For higher-performance flying or RC cars: Gens Ace 3S 45C for the discharge headroom. On a tight budget without sacrificing quality: Ovonic 3S 50C delivers honest specs at the lowest price of these three.
The Spektrum 2200mAh 3S is the factory-specified pack for the HobbyZone AeroScout S2 and several other Horizon Hobby trainer aircraft. That match is not accidental — it is optimised for the weight, voltage, and capacity requirements of the 1.1m trainer class. The XT60 connector, 3S voltage, and 2200mAh capacity are the standard around which most beginner electric aircraft are designed.
For pilots buying their first pack to replace or supplement the pack included in an RTF aircraft, this is the correct choice. 30C provides 66A continuous discharge — more than three times the current a trainer motor draws at full throttle.
Gens Ace is the brand most often referenced by experienced RC pilots when discussing pack reliability and cell consistency. The 45C rating provides significant headroom over a trainer's actual current demand — relevant for RC cars, aerobatic aircraft, or any application where burst current matters. Cell balance across the three cells is tighter than most budget packs, which translates to longer usable lifespan when maintained correctly.
For pilots who fly multiple aircraft types — trainer on weekdays, RC car on weekends — this pack handles both without being a C-rating compromise in either direction.
Ovonic has built a solid reputation in the budget LiPo segment by delivering honest spec sheets — the 50C rating is real and measurable, not marketing inflation. At a lower price than the Spektrum, it makes equipping two or three trainer packs per session financially practical for new pilots. The quality control is consistent enough that cell imbalance on arrival is uncommon.
The trade-off versus the Gens Ace is cell longevity under sustained high-C discharge. For trainer use — where peak current draw is moderate — this trade-off is irrelevant. For RC cars or aerobatics, the Gens Ace is the better long-term investment.
| Spec | Spektrum 2200 ★ | Gens Ace 2200 | Ovonic 2200 |
|---|---|---|---|
| Cell Count | 3S | 3S | 3S |
| Capacity | 2200mAh | 2200mAh | 2200mAh |
| C-Rating | 30C | 45C | 50C |
| Connector | XT60 | XT60 | XT60 |
| Best use | Trainers | Multi-use | Budget trainers |
All three packs use the XT60 connector standard and require a balance charger — see the LiPo charging guide for setup details, and the RC Batteries Guide for the full spec reference.
For most RC pilots starting out with a trainer aircraft, the Spektrum 2200mAh 3S 30C is the correct pack. It is the factory-specified choice for the most popular beginner aircraft, uses the XT60 standard connector, and charges correctly on any quality balance charger. The 30C C-rating is more than sufficient for a trainer's current draw — there is no real-world benefit to a higher rating in this application.
Pilots flying RC cars or higher-performance aircraft alongside their trainer should step up to the Gens Ace 45C for the discharge headroom. Those equipping multiple packs on a tight budget will find the Ovonic 50C delivers genuine value without meaningful compromise on trainer-class hardware.
