Hi all, I am in desperate need of help with a scooter battery issue.
I recently got six new 12V 20ah batteries for my 72V e-scooter, as the old ones were toast. I installed them and charged them up, and they show as fully charged (the momentary startup display shows around 80V, which is about right for new batteries in my scooter, from my experience). Then I start to drive and the battery display on the scooter immediately drops down to 3 bars, from 6 (fully charged). It happens almost right away.
I thought the batteries were defective/old stock, so I went back to the scooter store and got 6 fresh ones. Installed them, and same thing occurs. So it's something wrong on my end.
The old batteries would display six bars when fully charged, so I don't think it's the charger (which worked fine before the battery swap). Obviously those old batteries would start to die quite quickly, as they had 3500+km on them, but I would still have to drive several km before the bars would drop down to 5, then 4, and so on. The brand new ones are at only three bars right away on a full charge. I didn't do anything different other than replace the batteries.
I was going to bring it in to the store to get it looked at, but wanted to see if anyone on here had experience with this issue, and could give me some guidance. Thanks so much in advance for any help.
