Works well so far
Top balances which is what I wanted most and does so without getting too hot

Very happy 5 months in, doing their job
They are doing a good job cutting out from over charge from the cheap lead solar controller. Previously had explosion and fire.

No short-circuit protection
Product looked good but did not work correctly. The short-circuit protection does not work, this will continuously allow electricity to flow during a short circuit event.Very disappointed.
