Im rebuilding a 3.7V 1400maH battery pack. It looks like 2 700mah cells connected in parallel. Can I just use one large cell?

what type of cells are these? - /g/ (#106157666) [Archived: 242 hours ago]

appears to be some sort of battery

usecase of building your own cell battery?

Problem is that it's connected to a circuit. We don't know what it's doing or how it's programmed.

Hello, Satan.
If you're sure that the cells are connected in parallel, you can replace them with a single cell, provided the replacement cell has the same capacity as the combined cells. The capacity can be higher, but not lower, and of course, you'll need to make sure your replacement cell(s) are the same dimentions. If you have access to an adjustible power supply, you can often recover an over-discharged cell by bypassing the BCM and appying a 4.2v @ 200mA charge to the cells if they are too low. If a cell falls below a certain threshold voltage, the BCM will *not* allow the pack to be charged, thus giving the impression that there is a fault in the pack. You can also reuse the BCMs on other batteries, so long as you observe the voltage and current ratings for the BCM.
