Battery Management System Charging Circuit Diagram
With this circuit, we can charge a 3S battery for example and all individual cells will stop charging at 4.2V. Also, by having the two LM317 regulators at the input we have current limit protection but we are also able to supply the entire circuit with let''s say 16 to 20V and set the voltage that goes to the battery to 12.6V, which is the ...
