Battery Rebuild Ninebot PTR Elite +
NinebotPTRELITE+ replied to NinebotPTRELITE+'s topic in Segway (or equivalent)
As Chriull explained, the paired cells should be replaced. If one is bad, its partner (paralleled) cell should also be replaced even if it does charge back to nominal voltage. You can test cells separately without removing all the welding/solder connections. Just test bottom to top of single cell, if below 2.0 Volts, replace it and the parallel cell. Some people may consider a different minimum voltage, but I use 2.0 V as minimum to use in rebuilding a pack. I try not to use New cells in a pack of used cells. Keep New cells together in one pack on same BMS. Use similar aged cells in used -

Congratulations to HARALDL! No small task. I am so glad to see someone else avoiding the crazy prices they want for old stock manufactured batteries. I rebuilt one using older (over 4 yrs old) cells. Even that pack lasted two more years before several more cells failed. Pulled those out and replaced with used cells and I am again on the road. If you have the patience and time, you can keep these packs running well past their original designed life-cycle. Again, always use caution and all safety equipment. -

Find the seam. The top (small part) is actually like a lid. You have to slide a knife or other thin sharp object around the lip to separate the seam. Try not to break the lip so you can re-close the pack. I did not actually re-glue. Used duct tape to seal so I can do maintenance on the pack at a later date.

Replacement Battery Ninebot PTR Elite +

Sorry, the ebayer from Russia was the only one I have heard of except for some individuals doing their own. Sorry to hear your bad experience with the one from Russia. Since the PTRs are no longer being marketed in the US, I suspect the few being sold as new have batteries almost past their useful life. I am in my fourth year and have rebuilt one of three. Expecting failures soon. Lithium cells only last so long Please post if you find someone willing to rebuild. -

One more thing, the potential replacement BMS cited earlier in this thread had a discharge at 30AMP. I know the original 450 Watt Pack were designed at 20 AMP discharge rate. Not sure the rating on the 620 packs (elite +) . -

I know the packs are separate, but the power control board sees them both and can tell difference in output, and I am not so sure about the half and half approach. If I do not allow the charger to completely charge my packs and shut down, the pack will never get fully balanced between side 1 and side 2. I will get the output 1, or output 2 error on the same pack until I let the pack fully charge (ie the charger turns itself off). Thus in my opinion, you could not use two different (strength) half packs together on the some power control board. Note, I am not sure about this and if in a -

Good to hear from you. Sounds like you are experiencing all the same issues I did. Yes, my welder also tripped breakers. I only succeeded when I found an isolated outlet on a circuit that was rated for 30 AMPS . The outlets in most kitchens are rated 20 to 30 AMPS due to toasters, ovens, coffee makers, etc.) Others in the house are usually 15 AMPs - these will usually trip when you try to make the weld. -

Fold them on eBay (US SIte) . Just search for pure nickle stripping. I used the ladder style and trimmed as needed -

Are you talking about the NINEBattery app or the Ninebot App. We have no problem connecting with Bluetooth to the Ninebot App. If you did get a connection to the NINEBattery Apps. Were you able to view the voltage on all 60 cells in the battery pack? What cell phone did you use? Thanks for any info. -

I have had the same query out there since October 2018. So far, no one has replied that they were successful with the ptr elite or elite+. I have had the same results as you with three different android phones. Even ran a BLE checker to ensure the cell was compatible with BLE. ANYONE????

I know that there is a Russian selling the BMS for the PTR Elite on ebay. Not too expensive if you know that yours is toast. Once you rebuild the pack (one side), attach the original BMS and give it a chance to reset. I had to connect and disconnect (power lead) three times before it reset from showing failure voltage (about 13 Volts) and reported 55Volts. For the 450 battery, Found the exact OEM 18650 LG Cells out of Korea for $230USD for the 60 cells. They are 2100Mah . Pure nickel stripping and cell holders cost another $30, but was able to reuse the original 15S2P BMS's -
