I wanted to show you that pylontech system in parallel with a generic (15s!) lifepo4 system is totally possible. Both Daly and JK Active BMS.
3 Batteries are connected to a Lynx Distributor and all 3 Multiplus are as well.
1x JK 1x Daly and 1x pylontech US5000.
I wanted to comment on the lifepo4 linearity for example with 80A continuous at 50.50v for 90minutes increased the voltage to 50.60v today. So 0.1V accross 15 cells! and 4kwh absorbed.
The currents split themselves from the Distributor to the battery packs according to the kwh installed. So the bigger batteries get more current.
Having paid 55€ per 305Ah cell grade A I wonder what the disadvantage of my setup is. It is clear that the pylontech warranty is voided. But I quite like the setup of having a main BMS (pylontech) which limits the current to 80amps and the "dumb" batteries run in parallel being watched by their own BMS.
Am I missing something?
