I'm setting up trikes with Bafang BBSHDs. I plan on running 3 LunaCycle Wolf 52v GA 13.5 in parallel. Ridiculously heavy touring setup.
I have a 100W solar panel on each trike, with plans to add more on trailers behind each, which I previously used to charge a spare Bionx battery.
Short system description
Solar > Genasun GV-10 MPPT charge controller > 12.8V LiFePO4 40Ah battery > 12 to 26V boost converter > spare Bionx battery
I'm going to build a junction box on the output side isolating each Wolf with a Schottky 80V 100A diode so back cross charging through the output ports wont be an issue, SAFETY!
What I'm thinking is replace the 12 to 26V boost converter with a boost converter with 52/58V CC/CV regulation and running that into the batteries input ports which will also be parallel. I'm assuming that each battery's BMS will protect it on the input side and the CC/CV will control the charging
Now my question is does anyone know if the LunaCycle Wolf BMS will allow charging/discharging at the same time? The Bionx system wouldn't allow this. If you applied charging current it disabled output current to the motor even though the system would power on. Thus charging the spare battery and swapping.
Splitting the load among all of the batteries will maximize by distance because of the reduced load on each and add the solar charging will increase it further.
Would appreciate any help on the BMS inside the Wolf's
My other option would be to supply current in parallel to the batteries to the Bafang but prefer the charging option since it maximized my solar.
Thanks
