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?

Search on Amazon.com for "lipo charger". There are several options that will charge a single cell (1-4 cells, 1-6, etc.). Click here for one example.

Just be aware that many R/C-oriented chargers do not include a power supply, as they're intended to be hooked up to lead-acid batteries when out and about. (The linked item does not need an external supply.)
