Here are some pictures of the batteries and the install:
I’m working on the charge cycle. Currently the QuickCharge is set to “Deep cycle wet and shut off”. Seems to keep the voltage too high at the end so I have been monitoring and shutting it off manually. That temperature is from the side of the charger.
The batteries have stayed very balanced once the charger stops and throughout the discharge. I have measured about .02 V difference across all 25.
I haven’t done any long rides yet. Only about 8 miles so far.
I think I want a BMS to add low voltage cutoff protection, better charge management and more info about the battery state. I’m looking at different chargers too.
