OK so here's my dilemma. I have several of these 3.7v 6000mah rechargeable batteries left over from a separate project. I want to connect them up in series so that I can use 7 of them as 1 battery. My problem is that I'm worried that when I go to charge it (with a 25v 1.5amp charger) it will charge it unevenly or even damage the batteries somehow. So my question is would I be OK with doing this or would I have to dismantle the battery and charge each individual cell every time. I was reading up online but no one has really come to a consensus. Especially since the fact that the battery pack I am replacing with my home made one is made up of similar cells joined together in series. There is probably some sort of framework or a small chip which keeps the cells balance but regardless it should be doable I think, I hope. Thanks,
