Hi all, I’m struggling with something I’m hoping someone else has also had and resolved??
My BMS is not showing the full voltage of 26.4, and only 13.7?
Multimeter A (negative) and B (positive) directly on the batteries shows 26.4V so the series connection is good.
The white plug at C, if I unplug and use the multimeter and check the black and then each red wire in sequence I get 3.3, 6.6, 9.9 etc. right up to 26.4V on the last red wire so battery connections are good.
Once connected D (negative), and B (positive), these go to the charge controller, I only get 13.7V. I tried another identical BMS, both band new, and get the same result so I don’t think there is an issue with the BMS? My charge controller is also showing battery at 13.7V as its running through the BMS, and LED is on float which if not mistaken is trickle charge meaning the bank is fully charged.
Has anyone else had this issue? Any advice is seriously appreciated! I’m doing my head in. Thanks.
