The XTOOL BEC2440 is a flagship 24-channel battery balancer built for professional EV and lithium battery service. With 40A charging and 20A discharging current across 24 synchronous channels, it brings higher efficiency and greater precision to traction battery balancing, charging, and testing.
Built-in internal resistance testing and automated report generation turn complex battery work into a clear, documented workflow — so every cell is balanced, measured, and verified with confidence. Four-layer safety protection guards against overcurrent, short-circuit, reverse-polarity, and overtemperature, keeping both your team and the battery pack safe.
As a core part of XTOOL's One-Stop EV Service Solution, the BEC2440 helps repair shops handle modern lithium battery service in a single, reliable system. Faster balancing, accurate diagnostics, and dependable safety — engineered for the demands of today's EV aftermarket.
