Posted February 10Feb 10 I currently have a 10KWh Freedomnow battery, if I want to double this; is it a must that I stay with Freedomnow or I can get a different brand for as long as that is 10KWh?
February 10Feb 10 While it is technically possible to combine some models of batteries with the others, there's a lot of caveats and limitations. Some of them being: Voltage Cell count Chemistry BMS communication Warranty Based on that I can't recommend doing so. Upgrade as per manufacturers guidance, or sell what you have and rebuy from scratch.
February 10Feb 10 If it helps Zola I have a Frankenstein operation at my place. One is the same as yours 10/8 by FreedomWon, another is a repaired Livoltek 5kWh and the last one is 6kWh LFP DIY pack. The SoCs actually stay within 5% of each other and I use comms to the available 10/8 and because they so close its a good indicator for bank SoC. But @Youda speaks wise words they must be the same cell count ie only 51.2V can pair with 51.2v & 48V to 48v anything different and you looking for trouble because the charge settings of these 2 arrangements is widely different.
