[@Ethcircuits]

yes

[@muhammadbilal2000]

Well done, thank you very much. That's what I was looking for. I have two li-ion big flat types of cells, I will connect them in series. The voltage needs to be 8.4V when full and 6.6V when empty. For safety, I will keep the full voltage at 8.2V and 7V when empty. My question is can I just simply use an easily available 9V or 12V charger for it? Or if I want to have a USB charger, can I make one for it? Thank you again for the good stuff. You got a subscriber.

sir aapka video bahot achchha hai, ek confusion hai, ki power supply kitne ampier ka use karna hai

[@RajA-gx5ur]

Thanks! One doubt: total input voltage and input current of 0.29 amp means the max current sent into any battery at outlet by your circuit is restricted to 0.29amp? Suppose one set of battery out of 3 sets being charged at output can consume more amps your charger will restrict the charging amps?

Nice project bro I am working in such project too and i have some queries with circuit you designed As it looks the circuit only monitor the charging process and discharge process is not bypassed by the circuit and could you tell me how it will cut off when battery is under 2.8v? It's also a challenging matter and i have an idea but didn't try out yet. If you could find a way to bypass the discharge process trough another circuit that could have voltage drop, cut off function it will be definitely awesome. I think it can be done with relays as i don't know the nature of relays.
