Many thanks Mariska & Martin MallacootaPosted on Micha WatersTrustindex verifies that the original source of the review is Google. Awesome product , highly recommend itPosted on R One hundredTrustindex verifies that the original source of the review is Google. Purchased a 300Ah lithium battery to power my Waeco CFX50 car fridge and other 12v appliances. Very helpful and informative sales information. Easy to deal with and communicate. Product is fantastic. Think Lexus quality but with the Toyota price. Great value for money and highly recommended.Posted on jane wilsonTrustindex verifies that the original source of the review is Google. Cant speak highly enough of the service . Delivery prompt and through. When I had to return an item ( my fault) couldn't have been easier to deal with. Highly recommendedPosted on Bill MartinTrustindex verifies that the original source of the review is Google. New 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!
