Works great
Made myself a 21P battery and added a USB converter. Works perfectly as a power backup for my cabins WiFi and camera system. Would buy again in a heartbeat.

One out of 4 had a chip in the lid. Not worth sending back.
For the most part okay for the price. But one had a chipped corner in the lid. Will keep it and use it. Not worth sending it back.

Works just fine
I had to cut the ends off the battery holders to fit it into the case but besides that it matches the size of my APC batteries so it was any easy swap.Worth it to get it in a short amount of time over other suppliers.

Build your own 7 ah battery with 18650 cells.
I like the design, looks just like the AGM battery. The great thing is that the bad batteries can be removed easily, and the whole series, parallel battery can be rebuilt over and over again using the same case. The battery holders are included to space the batteries apart so they cannot rub against each other. The top snaps on, no glue needed.
