Electric vehicle lead-acid battery voltage is too small phenomenon and countermeasures float voltage is low (less than 2.18V) or discharged when additional power, insufficient charge, will have the following phenomena:. A low electrolyte density b c insufficient capacity. will produce a negative phenomenon sulfate, remote control toy car battery, it can be seen clearly small white particles (lead sulfate crystals) d. negative plates will be early expansion, early capacity recession. e. result in the early termination of life. Remedy: adjust the charge current, float voltage. Balanced charge, processing sulfation phenomenon.
