Hi Guys,
I am pleased to report that the removal of the BMS from my 45 Ah LIFE pack, has been a great success. By using a Cellpro PL8v2, I am getting more power into the pack and this is clearly noticeable on the steep hills I climb.
I have ordered 16 pieces 3.2v 120 Ah cells from China and will provisionally run my all terrain rover, configured as, 24v 240Ah. Eventually when I find a suitable trans axle with a 48V BLDC motor, I plan to reconfigure the pack.
However : right at the moment, I can't get the PL8V2 to charge the pack. I am using a preset that BM developed and sent to me, which has been excellent.
The problem started when I tried to initiate a charge cyl. and I got this error message on the PL8
"Bad Cell Count, Node Wiring XH"Please note that the current charge level of the pack is 25.4v
I checked the voltages, continuity and ordering of the 9 balance wires and I found that the small 22 AWG negative was open circuit, so I stripped the pack down and soldered it back in place.
This evening , I have checked the individual voltages of the balance wires and they are all correct, however the error message persists and I cannot charge my pack.
I would really appreciate any help, suggestions and advice that you guys can give me , to get things working again.
