Yesterday I (pre-) ordered my first torch (Astrolux MF-01) that uses Li-Ion batteries in a serial configuration (2S2P). From what I understand, the batteries need to have the same capacity and voltage, but there is a chance that the light might drain them at different rates. Does that mean that I need to check the voltage every time before I switch it on? Or only if I use / store it for a longer period? How much variation in voltage is acceptable, if I don't want to risk that the light turns into a pipe bomb?
The other thing I was wondering about is what batteries are suitable. I ordered the purple efest that are rated at 20A. Are they safe to use? Or doesn't that leave enough overhead, considering that the light draws nearly 16A in turbo mode? Would I be dangerously pushing the cells to their limit? It seems that Samsung 30Q would be the best choice if they were available as button tops, but I've only been able to find them as flat tops.
