Hi，

Yes, you can use batteries with a protection circuit, but please pay attention to the battery size requirements--X728-hardware#18650 battery dimension.

However, many batteries with protection circuits are too large to be installed. To avoid this problem, we require the use of batteries without protection circuits.

And please use quality 18650 batteries, inferior batteries will damage the ups board.
