I want to ask such a strange question, is it possible to combine Pylontech batteries (4x3.6kWh) and 2xLifePo4 280Ah on a common connector??? .
What I noticed in the documentation is that the pylontech charges the batteries at 3.467V (52V) during absorption and the Float charges at 3.4V (51V).
My point is that I have both types of batteries and I would like to use their capacity. When they are connected in parallel on the bus and the parameters are set in the BMS for 280Ah batteries, it should work safely.
Basically the charging would be controlled by the Pylontech BMS or not controlled by the Pylontech BMS and the Pylon BMS would adjust the charging current and voltage by itself like the other two BMS now, only the toy cables that come with the Pylontech can handle 100A continuously AND the charging from the MPPT must not exceed 100A, so I won't use the potential of the panels :).
So this would be a question of how long it would last and if it could be solved or if two more batteries could be charged, I suppose not, but maybe someone here has already tried it :)
Or I can use SmarShnut and set it to 856Ah, plus Abs.V 52V, Float.V51, Abs.Time 1h ...
Crazy or not??? : )
Thank you for your opinion
