Good for KS2 Corp battery packs
These work well. I had KS2 corp lithium battery packs in my RV, one of which was failing. Managed to get it working fine again by adding one of these.

Missing half parts
The other board and instructions were missing. It was taped shut so obviously missed from factory. I did order and received box that is supposed to have 2 boards
