ANSWERED Battery holds old charge, but does not charge now.

Recommended Posts

Hi there, I hadn't used my sondors thin bike for about 3 months, and when I went back to charge it, the plug sparked when I put it in the battery, and will not charge. I bought a replacement charger, (not a sondors official charger but a charger with similar specs) but it will not recharge. The battery still holds charge from when I had charged it prior to the 3 months, but will not accumulate charge now. Any suggestions? Should I purchase a sondors official charger? Or is it a battery issue? Thanks!

Edit: After checking the fuse, its seems to be still intact. Any ideas?

Sounds like you blew the battery fuse.  Look for the fuse port on the triangle battery, open it up and check it.

edit:  You can use other chargers so long as you pay attention to amperage and most especially cutoff voltage.  If your charger cuts off higher than its supposed to, worst case your battery could literally explode.

Hello @Gabe Van de Sande And welcome to the Sondors Owners Forum. Glad you found us and enjoy your stay.

Have you followed the correct charging procedure for a Sondors Thin? Battery power switch to off. Unscrewing  the controller to battery  connector. , Plug the charge cable into the battery before lastly, pluging the power cord into the wall outlet. The Sondors charging light will be momentarily green, the turn to red to show it is charging. Should turn back to green when full charged at a max length of time of about 4 hours. If you plug your charger into the wall outlet before connecting it to the battery it won't charge. 

Other ideas?, yea. Check the output of both chargers with a multimeter to see if they are both bad (doubtful). Every eBike owner should have a multimeter. https://lunacycle.com/electricbike-multimeter-perfect-for-ebike/

Let me know if the correct charging procedure, solves the charging problem.

      I am unable to turn the battery key that came with my Sondor's. See the linked video. Would welcome advice on what might be wrong and/or how to remedy the situation.

      I got home after a ride 2 days ago and my battery was down to 20% so I plugged it in to charge but the charger light stayed green and the battery was not taking a charge?  I contacted Sondors tech service ( Sean ) and he emailed  me back that it was probably a blown fuse in the battery.  A 90% chance that was the issue he said. Has anyone checked and or replaced the battery fuse on their Fold X ?? I am pretty handy with electrical fixes so if it is not too difficult or VOIDS the warranty I am glad to do it myself and save the time involved with shipping the battery & charger in for service.  Any feedback on this would be much appreciated.

      So I decided to go for a 52v upgrade on my Sondors Thin using the Luna Cycles 52V TRIANGLE PANASONIC GA 18650 14AH HIGH POWER AND LONG RANGE battery. I carefully measured and I thought I could just barely get it in to my Sondors Thin if I took out the bumpers for the stock battery and some of the cable guides. I got the battery and even after looking it I thought it would work (see attached photos). I used a Dremel to take out the bumpers that were in there and most of the cable guides in the top right. The battery looks like it was made for the box, dimensionally it fits like a glove, but (and I knew this was going to be the tough part) the hard box on the Thin just won't quite close even after my modes. I don't think I'm close enough to quite get it there either.
      I really like the look of the hard box case on the Thin, so I'm trying to figure out it:
       Is there some alternative idea to getting this thing to work in the stock box. I'd thought maybe there's some way to modify the hinges... or even cutting off the outer rubber on the battery might save a few mm. Any ideas folks? That's why I'm posting on the forum. Is there another form of hard box, maybe from the non-Thin Sondors, that might fit in it? Is there something dumb I'm just not thinking of here? I guess the final option is just remove the box and put in a soft triangle bag (such as the Luna Cycles one). Does anyone have any experience putts one of those on the Thin? And once I do that I might as well get an even bigger 52v battery, right? I've also got photos of it compared to the ElctroBikeWorld LT48.
      Appreciate any input anyone has. Thanks!
