5000mAh Li-Ion Pack
4S 5000mAh Li-Ion pack
Built for pilots who stay out longer. 5000mAh / 72Wh at ~300g gives efficient 4S platforms 10–20 minutes of airtime, often double what a same-size LiPo allows. Genuine Reliance RS50 21700 cells hold 70A continuous and 140A burst (5s), so cruise stays firm with punch left for climb-outs. Need harder freestyle current? Move up to the 4S2P.
5000mAh Li-Ion Pack
6S 5000mAh Li-Ion pack
The high-voltage pack for long-range and cinematic 6S builds. 108Wh at ~445g, about 40% lighter than a typical 6S 5000mAh LiPo, so more energy lands on the airframe, not the scale. Genuine Reliance RS50 cells deliver 70A continuous and 140A burst (5s) for mountain runs, tracking shots, and flights that stretch well past the ten-minute mark. Need harder current? Move up to the 6S2P.
21700 Li-Ion Cell
Reliance RS50 cell
Genuine Reliance INR21700-RS50, direct-sourced, never relabeled. 3.6V nominal, 5000mAh, 66g, datasheet-rated 70A continuous / 140A burst (5s), with 500+ cycles to 80% capacity. The same cell inside every Black Series pack. Sold per cell for custom builds, repairs, and spares.
5000mAh Li-Ion Pack
2S 5000mAh Li-Ion pack
Small pack, long session. 5000mAh / 36Wh at ~150g for lightweight FPV and RC. 70A continuous / 140A burst (5s) from the same genuine Reliance RS50 cells as our larger Black Series packs. Where a tiny LiPo burns out early, this keeps the pack flying.
10000mAh Li-Ion Pack
2S2P 10000mAh Li-Ion pack
Parallel power for long, hard runs. 10000mAh / 72Wh at ~300g with paired genuine Reliance RS50 cells. 140A continuous / 280A burst (5s). Li-ion cruise stamina with LiPo-class punch for ground vehicles, robotics, and high-load sessions.

10000mAh Li-Ion Pack
4S2P 10000mAh Li-Ion pack
No-compromise 4S endurance. 10000mAh / 144Wh at ~590g. The 2P layout doubles capacity and current vs the 4S1P (140A continuous / 280A burst for 5s). Built for heavy-lift, cinelifters, and robotics that stay on the throttle. Ten-minute flights become twenty.
