I have two 3cell battery (11.1v, 5000MaH). After fully charging them, I wire them together in parallel to increase the capacity for my project. Can I just take them apart (very carefully), desolder and hardwire the individual cells (in parallel) together? So basically increasing the capacity of each "cell"?
I have attached a diagram as well.

Electrically, you must ensure that you connect three cells in series in one assembly, three more cells in series in a second assembly, and then connect those two assemblies in parallel. Mechanically, you may find that the cells are welded together in the three cell packs and/or that soldering them back together will be difficult.

Hi tracecom,
That is what I am doing right now, but I would like to be able to charge them both as a single battery. Is the way I've describe alright to do?
