For the new battery bank of 24Vdc or 48Vdc which is composed by several batteries, minor difference of internal leakage current will cause undercharge or overcharge of parallel or series connected batteries. The frequent encountered Partial Stage of Charge (PSoC) make this situation even worse, as the result of rare opportunity to fully charge the battery. Battery Guard equalizes each battery individually and in the meantime monitors the real time voltage and temperature of each battery unit. The SOC difference will be iron out during charging.
