Hi All

 

I’m from north London and I bought a

Voilamart 1000W Electric Bicycle E Bike Rear Wheel Conversion Kit , I matched it with a 48v 12 ah battery which worked for about a year. I now tried to ride during lockdown and 10 mins in I find my motor shutting off . My lcd says error 06 and I can’t find much online that explains the problem. If you have any suggestions on what’s happening or how to fix it please comment.

 

Ps all of my wires are connected securely and I’m fairly new to ebike knowledge.

Thanks Marcel

My information points to low voltage protection but I don’t know how to interpret that information.

That sort of kit does chew through batteries; it may be that the battery is dead. That would fit with 'low voltage protection' too.

IMHO The battery was and is of too small a capacity for that motor, you may be getting severe volt drops.

The only fix I believe, which may be possible, is to get at the controller parameters and reduce the allowed maximum current to say somewhere between 12-15 amps, and see if that helps.

Best of luck

06 is likely under voltage/lvc as mentioned either an unbalanced battery or as Andy mentions saggy cells/voltage. Tell us the voltage reading after charging.

Hey guys

I literally just bought a multimetre to test the voltage etc and before I went to pick it up, I tried the bike and it is fully working again :s however I know it will probably stop again soon lol any suggestions to stop it going bad and cutting out during a ride again?

 

thanks for your earlier suggestions

Marcel

Ps I’ll be picking the multimeter up tomorrow morning

If it starts cutting out again and often then the battery is not really up to it, you need top cells for a 1kw hub and maybe more then 13s or more cells in parallel.

I would have though you need a battery with LG HG2 cells or Sony VTC6 and at least 6 in parallel.

Tbh a battery with those won't be cheap and you would be better with a good geared hub of between 250w & 500w.

 

Under voltage means the cells are sagging badly and hitting the min voltage needed, usually about 40v with 48v nominal battery though tbh 40v is a bit low. 42.9v is a safer lower limit without stressing cells.

The only way to use the battery is in low power use, but doing so every other bike will pee all over it.
