Delivery prompt and through. When I had to return an item ( my fault) couldn't have been easier to deal with. Highly recommendedTrustindex verifies that the original source of the review is Google.Bill Martin2024-10-31New BMS working well with my 20 kw system (16 X 3.2v 400a cells). Easy to set up using Overkill Solar app. Wiring loom was a bit short for my application but terminating wires made a more manageable cable layout. Much better system than my old static balancers and solenoid shut offs. So far system seems to handle up to 200 amps. LCD screen is a big bonus. This BMS is rated at 250 amps 48 volts, very impressed!
