I'm working on my first robot project. I previously used a 12V 6Ah sealed lead acid battery, but recently I aquired some 15 ASUS Li-Ion battery packs, each of them 14.8V and either 2200 mAh or 4400 mAh. The laptops have been discarded, and some of the battery packs seem to be dead.
The battery packs have an 8 pin connector. Inside, I assume there's a bunch of 18650-cells and some electronics.
My robot can handle 14.8 V directly.
How can I use these batteries? How can I charge them without the laptops? I'm a little put off by the idea of taking the 18650-cells out of the packs and rebuilding my own battery pack and charging system, but if that's what's needed I have to do it.
The packs are marked ASUS A41-A3 for the 2200 mAh ones, and ASUS A42-A3 for the 4400 mAh ones.
