5-1/4 x 1-7/8 x 11/16", 6.3 oz. Thunder Power "Pro Lite" 4000 mAh packs come pre-wired with a plug that mates with the 2-5 cell LiPoly cell balancer (TPB205). Cell balancing will keep your valuable batteries in top working condition. Monitoring your battery with cell balancer while charging gives you the added safety of an over voltage alarm. 4000 mAh cells can be discharged at 10-12C average discharge rate and up to 20C for short bursts.
