Dynamite LiPo cell voltage checker
The Dynamite LiPo cell voltage checker provides enthusiasts with an easy method of checking the voltage of an entire LiPo pack or individual LiPo cell. The unit checks the voltage of packs up to 6S and connects to the battery using the battery balance lead. Measuring the voltage of LiPo battery packs can help identify performance problems with each pack and in turn help prevent problems associated with voltage decreases.
