Had a 314ah battery work well for around 11 months. Died randomly with no load or anything happening, dropped straight to 5V (BMS issue). Email to service in Australia was replied to within 2 hrs with a list of things to try to wake the battery. Once I replied with my results (nothing had worked) they apologised and organised a return label, and said the replacement battery would be shipped as soon as I dropped my faulty battery off. Sure enough, within a few hrs of dropping mine off, I had a tracking number for the new one which arrived a few days later. Obviously disappointed about the failure in the first place, but can’t complain or fault the customer service and would purchase through WattCycle again.
