Hi Dogman and others,
I still have an expensive battery (Lifepo4 - 48V, 20A) with less than a year's worth of use not working... ARG... Since my last post, I installed a new BMS board. It was really straight forward and not a hard swap... Unfortunately, it did not solve my problem. I also reworked the connections on the charger to make sure the charger wiring was not the problem.
The charger indicator stays green when trying to charge the battery and the battery still will not accept a charge... I am listing a few questions that I hope you may know the answers...
The charger wiring connector I have been using from the beginning (charge hook-up) is very similar to the connector from the battery to the controller (discharge hook-up) . The controller connector is just much more heavy duty. I accidently hooked the charger to the discharge connector (one going to the controller). Do you think that might have damaged the BMS board or the battery?
I tried charging the battery again today after it sat idle for weeks. It still will not accept a charge. Again, (stupid mistake or not) after I tried charging it and got nothing, I pulled the connection and hooked it back up again. This time I hooked the charger to the discharge connector and the charger began charging. Quickly I realized I had the wrong connection and unplugged it…
So, A big question: Can I go ahead and try to charge the battery by hooking it up to the discharge connector without damage to the battery???? It seems like it wants to work that way and worth a try if it won’t destroy the battery….
Second big question: Anybody know where I can get the battery worked on? I don’t have the smarts, courage or equipment to tackle it any further….
Thanks to all for your review and help.
