So, when an AIO charges direct through the Battery cables would this particular BMS not work?It looks like the c- is for charging connection. So you connect the negative lead on your charger here. Whether that be via converter or from solar.
So this BMS splits the charging and load negative wires.
That's correct you need to get a different BMS. You need a common port BMS not a separate port BMS.So, when an AIO charges direct through the Battery cables would this particular BMS not work?
I can't help with the rest of your questions, but that diagram appears to show how to wire 2 batteries in parallel using this BMS.I bought about 30 units b2a8s20p and had no problems up till now (except for the password problem, which was resolved by an update of the app). Now I got my first b2a8s30p and I will try to figure out what all the new features are, like pre discharge etc......
I could not find any manual up till now. The only drawing I found does not explain anything to me. May be someone else is smarter than me and can explain this drawing below. I will keep you posted on this BMS once I have it running......
Cheers Hans
Hi there,That's correct you need to get a different BMS. You need a common port BMS not a separate port BMS.
I own two units B2A8S30P. Both show the same problem. If you trigger an UVP switch off and the cell voltages recover back to the UVPR threshhold, the discharge MOSFETs get stuck in the OFF Position and send a warning message........Has anyone got any info on the 300a jk bms model - b2a8s30p
Also I’m not sure what the C- is for ??
I have this problem with the 20p model:I own two units B2A8S30P. Both show the same problem. If you trigger an UVP switch off and the cell voltages recover back to the UVPR threshhold, the discharge MOSFETs get stuck in the OFF Position and send a warning message........
All of may B2A8S20P show not such a fault. They simply turn the discharge MOSFET back on and return to normal operations.
Any comments?
