The pre-charge current dissipates power in the resistor. Each successive pre-charge adds more power so if the resistor has not cooled between operations then the temperature will rise. Frequent pre-charge operations will cause the temperature of the resistor to increase, potentially to the point where the resistor overheats and fails.
In electronics, a bleeder resistor, bleeder load, leakage resistor, capacitor discharge resistor or safety discharge resistor is a resistor connected in parallel with the output of a high-voltage power supply circuit for the purpose of discharging the electric charge stored in the power supply''s filter capacitors when the equipment is turned off, for safety reasons.

The energy from cells of high capacity is transferred to cells of low energy and the energy of the multiple cells is balanced. The energy is transferred in a single direction determined by the energy gradient. For the battery pack composed of many cells, the balancing time is long. 3.2.3 Transformer-Based Balancing Topology
Resistor value to discharge the battery Ask Question Asked 3 years, 11 months ago Modified 3 years, 11 months ago Viewed 808 times 1 $begingroup$ I had a LiPo battery with specifications of 14.8 V, 2200 mAh, 23.6 Wh …
A battery acts like a pump which provides energy to do work on negative charges to move them towards the negative terminal, and hence creating an electric field. Now, due to this field, when a wire is connected to make a circuit, electrons move from negative to positive terminal, thereby making electric current.
