That’s very small minded. Like every other forum there’s good and bad posts. I do though have to agree with some that the cost of the bikes should at least have branded name batteries instead of cheap Chinese crap.

Don’t know how you come to that conclusion, why should a Facebook user that’s an electronic engineer not be so informative as you? If you are qualified what does it matter which forum you comment on? PS : I have another 2 batteries that are older than my wisper one and don’t need replacing.

I agree, I have 12 dead cells, so far managed to recover 6 using a psu. The other 6 might have to be replaced as they are very low & weirdly show the negative and positive wrongly on volt meter. Join a FB electronics group for help, lots of very educated people.

I have bought a second hand battery but I’m trying to also have my own repaired. Spoke to an electronic engineer who was very surprised there’s no wiring diagram or information inside the battery.

Unfortunately not, I bought it.

Hi David , I’m not sure as I got passed from one to another that had more knowledge about batteries, sounded a bit foreign. BTW the battery is 4 yrs old. Hardly been used, I thought it was in hibernation. I’m actually questioning myself if the last time I charged it , it actually charged. I...

I’ve sent you a PM

Thanks David much appreciated that’s a better response than the phone call I had with your premises . I will pop the battery in when I’m next in the area if I haven’t got it sorted by then.

Thanks but it’s a bit expensive for a 2nd hand battery with no warranty. Mine was never left in a discharged state either or so I thought. I believed 4 month in hibernation was fine. At the moment I have another bike to use so I will try to find out what’s wrong with the battery first...

Thank you for your kind offer, I may be down your way in the spring, if so I will give you a shout. The battery is showing 38.2, I know it should be about 42. I held in the power button for a while in the hope it might have been awakening it from hibernating. The battery indicator shows full...

Hi, did you manage to get new cells? I seem to have the same problem with my battery.

Interesting that I have the exact same problem after putting my battery into hibernation and lights showing the same but when I rang Wisper yesterday I wasn't given any info about sending it to be reset. Told to either buy a new battery or sell the bike if I didn't use it regularly.

Thanks, I will await your call.

Thanks, I have indeed looked on your website and d/l the 806 Torque display manual but no matter how many times Ive followed the instructions I don't seem to have the speed feature. I only appear to have M/KM, Backlight,( BLT)Time and Trip/Total. Ive tried changing the display from Miles to...

Found the problem with the high/low. The repeated turning the bike upside down must've broke a wire. Ive suggested once he solders it to put it back to 24v battery and get rid of it. Will be back in a bit once I know. Thx
