Keep your batteries in delivering peak power and performance in your RC car, truck or truggy with volt meters, multi-meters, checkers and testers that make it easy to see what's really going on inside your packs. Check NiMH and LiPo voltage, and monitor cell balance easily. Low-voltage alarms prevent over-discharging when using LiPos in older RC cars and trucks. Full selection includes Hitec, Hyperion, Spektrum, ProTek RC, Traxxas and more.
