I have a few Li-ion batteries which I want to use in series to have max voltage. But the problem is that the charger I have will not be able to charge the batteries in series, but will be able to charge them in parallel.
So how can I connect the batteries in a way that I will be able to charge them in parallel but use them in series? I'm new to these Li-ion batteries and i have seen the damage they can do I wrongly handled, hence I am not so eager to experiment with something that can blow up in my face, literally, hence the question here.
PS: Batteries are Samsung 18650 all are working
