Is there any news about Iron Korea company?

How's going repair? Did you fix the problem?

"Costi Plamadeala" Inmotion doesn't sell BMS separately. But BMS can be fixed, just remove bms form cells, chceck fuse, and chceck input and output mosfets.

Hi i had the same problem in V5f, there is high propability that your battery pack can be repaired, you can charge cells with 1s charger but it's not good idea if whole battery pack have low voltage. First disassembly battery pack, just to do some measurements on cells, dont disconnect, desoldered anything just remove foil and you are ready to go. Measure voltage + and - on whole pack (not in bms output xt60 but on the soldered to BMS metal sheets from battery), and on all cells if one cell is drown 1S charger will be enaugh, but if whole pack is drowned 1S charger is useless in that case you need to use DC-DC stepup converter. Get DC-DC stepup converter with CC (constant current) and CV (constant voltage) something like this https://allegro.pl/oferta/1500-w-dc-dc-step-up-stale-napiecie-regulowane-12366253886 , i have https://allegro.pl/oferta/900w-dc-10-120v-boost-converter-step-up-regulator-12289700555?utm_feed=aa34192d-eee2-4419-9a9a-de66b9dfae24&utm_term=desc-yes and its even better than first cause you can see what you set before you connect output to battery pack. If one cell is drowned, just pullup to the rest, and if whole pack is discharged and voltage on separeated cells is the same (no need to be exacly the same but near by) charge whole pack with 60V and 500ma, chceck temperature on batteries and if any cell starts to get hot stop charge immediately. When pack gets 60v charge you can connect origianl power supply and continue charge. You can contact me on private and when i have free time i can guide you how to do it.

I will try to make tutorial with photos how to do it in V10 and i will also give some important informations from my previous repairs.

Hi i'm sorry but i cannot agree with mrelwood, and sorry for my english. First don't test halls with motherboard connected to battery pack, it's not nessesary risk. Better option is remove motor from the shell and connect 5V or less power supply to connector (black - negative, red - positive). Second, i know that is not logical but measure color cables not to black but to red wire. "so there aren’t too many different models available" there are many models but most important thing is to get bipolar hall sensor on good voltage. Hall sensors have description H149 it's propably OCH149 but you can use ss49e my friend use ss41. Check axle and cables. I have removed V10 motor if you want i can show you how to measure hall sensors. Just contact me on private.

I had similar sound in my friends V10 and it was cables to coils, your cables doesn't mount properly. They propably touching side of motor, this side of motor that you disassembly have stripes inside and cables touch this stripes. Sorry for my English.

You dont say anything about warranty. Do you have warranty fot this wheel?

Sorry but i must agree with "alcatraz" i repaired a lot of V10 and they have BMS problems, in 2 battery packs with black BMS i had 2 cells drown below 3V, and it was the same cells in both 2 packs i think it wasnt coincedence. There is high propability that your battery pack is unballanced, in this time it propably can be fixed except BMS. If you have green BMS all pack can be repaired unless one of cells goes below 2.5v.

Hall sensors are SS41F.

LOOK INTO MY EYES

As you know your wheel have 84v battery pack so there need to be dc-dc converter to pull down voltage to 5V. Every dc-dc converter have max current that he can carries and you can check it in datasheet.

To chceck battery you need to disasembly battery pack. All BMS measure voltage between cells, and if any cell have lover voltage than others BMS wil block output, you need to chceck if voltage on all cells are equal. If not, you need to change broken section (cells need to be the same as others). After repair BMS will be locked, to unlock BMS you need to assembly repaired and ballanced pack, connect pack to wheel and try to charge.

Charging battery outside is possible, BUT if you don't have enough expirence don't do that. And dont think you will charge battery outside cause propably pack doesn't charge with some reason, unballanced cells, broken bms. Do you have any electronical skills?

I repaired few Inmotion v10, if you change motherboard and new wheel still say please repair it means that you need to repair motor, it can be cable problem, or/and axle problem or hall sensor problem. To repair motor you dont need to have special skills, just figure it out what happend. If i get some more free time i can guide you online to diagnose problem and maybe help you repair your wheel.
