  1. yes there are two 15s2p packs in the battery. I believe they work in isolation from each other, they are not wired together, and the Elite recognizes them separately as battery pack 1 and 2. i think it is a separate pack to power each wheel, hence my thinking the different capacities of each pack would not matter and they do not interfere with each other. can someone confirm this or tell me this is a stupid idea. I have discovered my battery welder trips the electrics, so if the above is not an option then i will have to solder a new pack of 18650's which i am not keen on.
  2. can anyone tell me if i can use the good halves (30cells with working BMS), of two different battery packs together to make one full unit. I know they are used in isolation but are different ratings - one high capacity ninebot elite +, one standard ninebot elite. this would be a great short term fix if possible
  3. Thanks Chriull, I have had this battery in and out of the ninebot several times, as it was working immediatly after charge then after a short while giving me the warning, so i presumed a few cells had gone but it is strange that it is reading ok across the cells but not the terminals. Do i need to reset the BMS to test it? if so do i remove the bms white plugs connecting small white wires to the cells or unsolder the main red black charge/discharge leads?
  4. here are my readings across the cells vs across the terminals plus the error reports on the two seperate batteries (one large capacity the other standard).
  5. Ok a few questions here - any advice gratefully recieved. I got two faulty elite battery packs - one high capacity, one standard. on both packs one side has gone down so for a quick fix, could i use the good side from the high capacity and the good side from standard together as one complete pack? I don't go long distnaces as these are used in performance - would this work or am i walking into disaster?? second Q - i was about to rebuilt the faulty pack but did a quick vault test first - the pairs of cells read as expected intervals of 4v all the way up to 60v, but across the terminals I'm reading 15v? is this a faulty BMS or if not any theories?v
  6. Still tinkering with my battery - mainly out of fear before i get welding but I was looking at the BMS when i came across this on ebay. If my BMS is not working (Hypothetically) could i replace with one of there? I'm only curios, but might need this down the line.
  7. I have been a member for a little while and been posting quite regularly but still unable to send any messages. yes i have read the intro page but assumed i would be able to send a message by now. is this an error or can you tell me what i need to do???
  8. Sorry the cheap cells bit is irrelevant info - I purchased an old broken elite to harvest the BMS, have a look at battery build and harvest some other parts. The machine was not at all functional and had a few mismatched bits - so i assume it had been rebuilt. The cells were 2000mah so rather than try and harvest them for a rebuild i would like to buy new cells - and make sure they are the correct ones. For your interest though, i have attached a pic of one of the cells. I still need to know what cells i need for the an elite battery and elite+ battery rebuild.
  9. So the battery i opened up had clearly already been rebuilt using cheap unbranded cells. so I need to source correct replacement cells for a ninebot elite and an elite+ (i have one of each). samsung 25r's are pretty easy to source here in the UK, will they work? - 18650/2500mAh/20A INRs what mah do i need and what other ratings etc to be aware of to get the correct cells.
  10. ninebattery app not connecting despite trying everything listed on here and using several different android phones with different os
  11. what is the nickel stripping you use for the weld, it makes the job look really neat and professional, all i can find is basic nickel ribbon or the ladder style stuff. i would like to use what you have used as it has the tabs needed as well - is there a link, or what do i need to search for?
  12. It states it is the same BMS for elite and elite+, are they interchangeable? I have a few BMS's from different batteries, so hoping not to spend the money unless necessary.
  13. Do you have a link? I'm getting desperate for a new battery or battery rebuild and not getting anywhere fast! - on foot or via a ninebot (sorry couldn't resist)
  14. Regarding the BMS - I have one battery that is completly dead, i don't know what has happened but i was hoping to salvage the BMS, is there a way to test them, or does anyone know if there is a replacement available?
  15. I just re tried it with the handle bar inserted - realised i was trying it without that but it made no difference except i could see the bluetooth signal. it was flashing until i connected the ninebot app then goes solid but still nothing from the ninebattery app apart from the BLE not connected. Has anyone else managed to make this work on an Elite? maybe it doesn't work on the elite, but if anyone has i would be interested in knowing how you made it work.
