I was going to post to ask with help in balancing the battery, but today it fully charged for the first time since February.
Battery was described as 52v 17.5ah Lithium battery pack using Panasonic or Sanyo NCR18650GA cells
sticker on battery says 2017, but I purchased in January 2018
I connect charger to battery, turn the battery on then switch the mains on.
I leave the charger on until the leds show its finished
Why does it mainly charge to around 90% then very occasional fully charge?
