E rider scooter batteries?

Just down the workshop manual for the xm5000. You only need 2 positive and 2 negative wires. Others for onboard chargeing etc not needed

E rider scooter batteries?

Depends on your low voltage cutoff on your controller. One of mine is 60v the other 70v. Yes 4 5s in series to give 84v hot, 3 in parallel to give 15ah

Ahh so up around triple the price. I'll continue to see your progress. Might look at doing something like this in the future. For now lipo's will do. Might retire them to the bike later down the track

E rider scooter batteries?

10 modules wouldnt be cheap!!, Did you get a BMS too??. Lipo's are definitely more bang for buck. I have tested my scooter using 12 5s Turnigy 5000's. 84v hot off the charger. Set the current at 80amps and things look promising. Gets to 60-70km/h easily enough. Waiting on my charger before i go with...

E rider scooter batteries?

Would getting rego be a problem with Lipo cells ? Also the thought of individually balance charging 9 or 12 or 15 cells every 2-3 weeks sounds onerous. However, your option is far and away the cheapest way to get a 36 or 48 or 60ah pack into the bike. I hope those Hobbyking cells stay on sale while...

E rider scooter batteries?

I have been looking into Lipo option suggested by Jordan. 6S lipo cells are 22.2V or 25.2V at full charge. 3 in series gives 66.6V nominal voltage or 75.6V at full charge. 4 in series is 88.8V Nominal and 100.8V at full charge. The maximum normal voltage with 24 LiFePO4 cells would be 87.6V. Would ...

E rider scooter batteries?

There should have been an isolation switch / circuit breaker under the seat. There is a very large thread on the V is for Voltage forum on the e-rider and the guy strips it down and repalces a controller, etc with lots of pics. May be helpful to you. http://visforvoltage.org/forum/11326-erider-8000...

E rider scooter batteries?

Yes i did the maths on the battery setup. Using leafs was going to be around $2500, with BMS included. Using the CALB cells was slightly more i think. I picked up the Lipo's from Hobbyking for $80 a pop, Bought 9 for $800. 75v 36ah should get me moving nicely. Had the auto Elec guys sort out my wiri...

Wires are off the original harness and not the controller (Yuyanking brand). I've take it up to an Auto Elec to get sorted

E rider scooter batteries?

Well ended up buying 9 6s 12000ah Graphene lipos. Were on special and too hard to pass up. Will run in a 18s3p configuration for 75v 36ah pack. Will bulk charge majority of the time and balance if needed. Will make a build thread.

E rider scooter batteries?

Thanks, i do have the option of a Kelly controller or might go sabvoton (150amp). Both similarly priced i believe. Just need to sort the battery dilemma first

Cheers

Cheers, i've got one local here for $700. Controller has been swapped out for an ebike version (72v 80amp), so a much simpler setup paired with the QS273. I'll have a look at these cells.

Ive recently aquired an erider scooter i believe that needs new batteries. Does anyone have any recommendations on a replacement?. Ill be running a QS273 hub motor with a 72v 80amp controller. Was thinking lipo as the cheapest route but are there any viable lithium options (without costing a bomb). ...
