Are you able to make a charging cable That I could use with my balancing charger ? Example I found instructions to make special cable to attach to drone battery To be able to hook up to balancing charger for RC
Thanks for the vid. Could you please make a video how to wake up ninebot f40 bms? I have tried many things similar to my solar system bms but none of the methods worked out. All cells have 4.1v although there is no output voltage coming from the bms and it's flashing red. I don't see any reset button. It does not take any charge cuz the battery pack is full. Probably the thermal protection triggered when I left my scooter on the sun for half day. Can you help?
My battery has 41.1 v and won´t wake up. It worked before and was at full charge when it showed 1 bar on the dashboard. But battery light was still Strong blue so i put it in charge and then it would not wake up anymore it blinks 5 times red and dies. (Battery still at 41.1v) do you know what it could be? Thank ypu Already
Hi, from my experience, the cells must be around 3.2V for the BMS to wake up. If the bms was closed and you charged the battery directly, the bms will fail to open. Try discharging it with a dummy load until 32V, check that voltage on each cell is right and try removing and reinserting the bms. If that does not work, order a bms from aliexpress, is easier than trying to reprogram or fix it.
Dude, could you bring me some light?! I would like to use some of your experience with Segways since I´m a noob. :) I just bought an used NineBot ES2 with 2.000 km history. Have been using it for 4 days and yesterday I was recharging it after a 6km trip, at 65%, and I got to know that I should ask the previus owner to unbind it from his account in order to let me bind it to my brand new Segway account. After get it done I changed the old device name to a new one and the app crashed while "loading screem" and the device display turned off and now it´s dead. :( The current status is: I plug the recharger, nothing happens on display and rear red light get blining in a 2sec interval. I press Turn On button, same as above. If I press and hold Turn On button for a few seconds, the rear red light turn off and stop. I have tried hard reset, holding break and accelerator for 5 secs and then tap Turn-On button. Nothing happen. I don´t know what else could I do.
Hi. That sounds like something happened during firmware update or something else. I saw others flashing custom firmware to their E-scooters, you might want to try this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Kba7yK9NV6c.html
