Gentle Battery Regulator

Battery and Charger Diagram | By: Diagram mania

This trivial but very efficient circuit protects a run-acid battery (12-in opposition to solar battery otherwise car battery) critical of overcharging by a solar module once the thing light is too brainy otherwise lasts too stretched. It does so by energizing a fan, opening by a low tempo once the voltage is approximately 13.8 against […]
