Radrover 6 Plus
Battery Model number: APP00356 13INR19/66-4
The battery worked fine last summer, charging and all. The battery was stored indoors for winter, half charged. Checked it out occasionally during the winter, showed half charged every time.
Took it out today, checked it, nothing, no lights whatsoever when pressing the button on the charger.
Plugged it in to charge it, charger showing green light and the battery shows nothing while plugged in to the charger.
Any help or solution would be greatly appreciated.
Thank you
Serge
Essentially the same for me. Charged the thing just once, stored in the bike indoors without temperature changes and now (it's fully discharged says the bike) no lights or signs of life when attempting to charge it a second time.
Any help would be appreciated!
My daughters RR6 battery did the same thing over last winter. As hers was still under warranty, they replaced the battery, all good now.
Exact same battery (APP00356 13INR19/66-4) suddenly stopped charging.
This version has two ceramic surface mount fuses that are soldered onto the BMS boards.
Since both fuses checked good I suspected a bad solder joint so I removed each and resoldered.
Both show continuity to the BMS board.
I checked the charging fuse all the way to the charging port (should have done that first) and it was all okay.
Well, that leaves the BMS boards as something needing to be replaced.
If any of you have a source for whatever BMS boards are used can you please share?
People are rebuilding these so something is available somewhere, right?
