I have a small 3.7V 100mAh Lithium polymer battery. This is just like any other Li-Pol battery, but it is smaller.
Like any rechargeable battery, I want to recharge it. From what I found online, I see this technology needs a different process to recharge than usual, but there are products that do it for me and I just need to plug cables.
Now the problems begin. I searched in online stores, like eBay and every product says 2S or more (this means 2 cells). Maybe this is good for people that have big Li-Pol battery, but not for my purposes.
So, can I just recharge my one battery with one of these? Will doing so cause problems? Or if it need 2 cells, well, I use two of then in parallel (or in series) and do it. This is not the best solution...
Can someone recommend a good charger for just one cell or the proper method for charging multiple battery cells?
