Quick shipping inside USA. Excellent product. Just plug and play
Very good shape, being taller than usual, and taking less floor space.
This monster, having so little foot print, has enormous amount of juice. Over 4kWh!
App is showing right amount of % left in battery. I would give 4,5 star because 3rd party software didn't work with this BMS and humsienk own app is lacking advanced mode to see more info and statistics. Like cycle amount. But for casual use, it is enough.
Very highly recommend so far.
Replaced 4 12 volt lead acid batteries to the 12volt 100ah lithium batteries. Night and day difference.
