  1. Connecting two Lifepo4 ​​batteries with different brands in parallel

    rudyto85 replied to rudyto85's topic in Batteries
    After a detailed test, it turns out that a 100 Ah battery is 48V and 200 Ah is 51.2V. Also different BMS and without communication each other.

    Thank you good advices. Cells in the 200Ah is 16 and 100Ah is 8. About recommended charge voltage I`am not sure. Is it possible to make communications between this to different batterys (BMS)?

  3. Connecting two Lifepo4 ​​batteries with different brands in parallel

    rudyto85 posted a topic in Batteries
    Hello, I have 2 different brands and different capacity LiFePo4 batteries (200 Ah and 100 Ah both 48v). Bigger one can communicate with my inverter (GROWATT SPH5000), but small one not. Also batterys are with diferent BMS`s. Bigger battery can be charge/discharge with max 200 A, small one max 100 A. GROWATT SPH5000 charge/discharge max with 60A. I was thinking to use it as I connect both batteries at parallel and connect only bigger one to communicate with inverter, bacouse inverter does not charge or discharge without communication. What you think is it safe and is it work properly?
