This is the Traxxas LiPo cell voltage checker and balancer with the #2938X adapter for use with Traxxas iD batteries. This can be used to check cell voltages on 2S, 3S, and 4S Traxxas ID LiPo batteries, and also to equalize the battery pack cells if they are out of balance.
The Traxxas LiPo Cell Voltage Checker/Balancer connects to Traxxas LiPo batteries using the included balance lead adapters. Use the LiPo battery checker to view individual LiPo cell voltages and overall battery charge in the field without a charger. The battery cell checker works with 2, 3, and 4-cell Traxxas LiPo batteries and alerts you when a battery cell is out of balance.
A voltage balance function equalizes individual cell voltages to keep your LiPo battery in good condition.
