💡 Always repair in a fire‑safe area. Li‑ion repair carries a small risk of thermal runaway if cells are already damaged. 💡 Always repair in a fire‑safe area
Most cheap repair tools cannot balance a pack; they just charge the whole series. The UBRT-2300 employs a resistor-based active balancer that monitors each parallel group. During the repair cycle, it will bleed off excess voltage from high cells and trickle-charge low cells, ensuring the entire pack terminates a cycle with a Delta V of less than 0.01V per cell.
