I'm currently working on a project using an ATMega328 which I plan on making into a PCB.
I am essentially making a smart charger for a ~12.6V LiPo battery which will be charged via a cars alternator when the car is running. I have the rest of the components selected and tested to detect when the car is on etc. I am now looking for a safe and efficient way of charging this LiPo battery.
I have been looking at the TP4056 charge controller but I have no experience with such controllers and would love some input/recommendations.
The TP4056 is designed to charge a single, small, isolated LiPo cell (not connected to other active circuitry), and is not designed to be connected to a microcontroller, or for load sharing.
For LiPo cells in series, you need a balancing charger, which requires expertise in analog circuit design.
