RCG Racing 3.7v (1S) 500mAh Li-Ion Bateria Do Rock Crawler FPV

Fits the 1/18 crawler perfectly, and the 500mAh capacity gives me a good solid run before it needs a recharge. The JST SM-2P connector clicks in snug, no fiddling with loose wires mid-crawl.

The JST SM-2P connector made swapping the old battery effortless, and it gave my crawler a solid 25 minutes of runtime on a single charge.

Was a bit worried about fit, but the 500mAh capacity fits perfectly in the crawler's battery tray and gives me a solid 20 minutes of run time.
