I purchased a brand new bike direct from a known company with stock 750w BBS02 Bafang center mount motor and upgraded during purchase process to a 52v17ah battery. Upon receipt the bike worked great. I then charged the battery to full for the first time and got an error 7 code that the battery voltage is too high.
The seller states that the firmware needs updated to accept this battery and sent me a program, a file and a cable.
I have attempted to update the firmware on 4 different laptops unsuccessfully. Feeling completely and wholly frustrated at this point as I have to either discharge my battery or not fully charge my battery just to have an operational bike. There are reportedly other customers who have received their bike with battery upgrade functional.
Short of sending the bike back (costly for them), do any of you have any solutions? Someone suggested using an eggrider. Would that work if the firmware is reportedly the problem.
Does anyone have a firmware upgrade that actually works? Clearly the one I was sent doesn’t. They are sending me a new cable to see if this is the problem.
They have offered to downgrade the battery. Yes I know this is an option, however I ordered this combination because it was offered and others report it working as designed. The seller should stand behind their products I shouldn’t have to compromise because they forgot to update the firmware before shipping it out.
Any help would be greatly appreciated. I am not a computer programmer (and do think the fact I have to do this on a brand new bike is completely ridiculous) however I am willing to try if it gets the bike to function as purchased.
Thanks
