RCG Racing 7.4v (2S) 600mAh 1/16 ドリフトカー用交換リチウムイオンバッテリー

My little drift car runs for about 20 minutes now instead of dying after 10—the 600mAh capacity makes a real difference. The JST connector snapped right in without any fuss.

Dropped this into my Retro 86 and it fired right up—the JST SM-4P connector fit perfectly without any fiddling. Run time is noticeably longer than the stock battery, and it’s lighter too.

The JST SM-4P connector snapped in perfectly with no fiddling, which is a relief since the old battery was getting finicky. It holds a charge well and fits the tray snugly, though I wish it came with a tiny bit more capacity for longer sessions.
