Worth having a good think about for sure. I had great service from Jenny at Docan Technology(Shenzhen) Co.,Ltd. 4 x Catl 304Ah cells for $591 delivered to Portugal. Never balanced for nearly 2 years in use & still within a few mV of each other.Have you considered purchasing the cells, battery management system (BMS), and if you really feel it necessary, heating pads? The DIY approach.
