5000mAh Li-Ion Pack

4S1P Black Series

$99.00

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.
