I tried my New Ninebot one E+ for the first time last week. Yesterday I took it again (had it inside the house and it said 15 km left in the battery) but after 500 m it turned off and I fell pretty badly. It was probably below 0 degrees C. It was not possible to start it again but after a while it was fit for fight again. Do you think it was the temperature that turned it off or...? Pretty scary if not
Winter coming.. ;-) Li-Ion batteries like warm weather - and perform much worse if used in cold weather, also deteriorate much faster in low temperatures. Thanks to riders from colder countries additional functionality of the Ninebot Z smart BMS had been found... Ninebot Z smart BMS is closely monitoring batteries temperature (please note that this is different sensor than controller temperature - see the difference on the pics below - controller temp is 16 deg.C while battery is 18 deg.C not only in terms of overheating, but also for too low limits... this may be disappointment to a few users who got stuck after longer break in the trip in cold weather, but in fact it is SAFETY feature protecting rider from over current / switch off during the ride, and also protecting batteries against destruction (use of Li-Ion cells in low temperatures destroy cells quickly) So - If the battery temperature falls below certain limit (not yet found - but probably 0 - 5 deg Celsius or similar - please post your comments) Z10 will not turn ON ... So - this is general info for ALL unicycles - in winter conditions - never leave it in the car trunk or any other place with temperatures below room temperature - keep it warm before the ride - during ride battery will heat itself, and after the ride - put it back to the warm room. Do not make longer stops outside if weather is cold, for sure if it is below 0 Celsius.
Anyone know what the discharge rate is on the 18650 cells used in the 320 Wh battery? I'm assuming that the discharge rate is the most important spec to meet or exceed if I'm going to rebuild a battery using new cells. After that, I'll look at cell capacity. Any other handy hints I should know before plunging in? My son builds custom light sabers, and wants to build his own battery packs for them and other projects as well. I told him I'd share the cost of building a battery spot welder if he'd rebuild my battery packs for my 9bot E+. Don't worry, the spot welder will only be used outside, with all the proper precautions taken to ensure a high degree of safety. Ultimately, I'd like to use the best cells possible for more safety and range for the EUC.
