I have a 16s 48v 280ah battery. The 1st cell reads crazy out of line no matter what. I have top balanced, rearranged cells, and created an entirely new harness. After installing the new harness tonight, I received the attached readings. I pulled cell one and it read 3.4.
Have you measured the voltage between pin 1 (negative cell 1) and pin 2 (positive cell 1) on the connector that plugs into the BMS?
I went up through the harness - each went up by 3.4 or 3.5.
How does that solve the issue of the BMS reading 1ish volts, regardless of the cell, when a DMM reads the same cell at 3.4? The BMS isn't reading the cell voltage correctly, hence bad BMS.
If you buy good shit you need no stickin support or warranty. Bought 4 so far and they all work flawlessly.
Que? It has bluetooth built-in why would you need a module? did you get yours from the 90s?JBD fan here. All my JK's have no way to interface with them. The only jacks are the cell leads port and the heater wire port, no way to plug in a BT module.
For the most part I agree. But stuff happens. And when it does you want good support snd warranties. Overkill has both. Really their only issues are the current limit, and the passive balancing. But they are still solid BMS’s.
Now just turn on and configure the internal balancer and give it some time (week or so) and it should balance out those cells and keep them balanced going forward.
Should I not top balance them again?
