This Battery Charger circuit allows you to charge the battery 5A constant current source that stable over time between recharging.
Charging process is accompanied by the emission of diode D1 – AL310A, and D3-AL310B. IC A1 – 142EN2, Transistors: T1, T3 – KT815, T2 – KT819 (radiator), T4 – KT819. Zener: D2 – KS156, D3 – D814V. Resistors R4 and R5 is wound nichrome wire. 220V/15V transformer designed to power 100 W. Current leads (marked on the chart) must cross section of 0.5 mm2. The circuit is protected from short circuit the battery plates.
