Customer brought me same e-bike battery to check and main fault was that water had gotten inside battery case and made alot damage to cells, I made new battery pack and this video helped with the bms reset, thanks and greetings from Finland.
Thank you. It worked like a charm. My battery is from 2016 and it stopped working exactly as you described. The reset took me 10minutes and it is now charging like new.
Hi, thanks for the video. Bike: Helkama Lounatuuli with similar battery in Finland. 3-4 years ago I got complaint that the battery won't charge. I followed your guide and got the battery charging and working again. Now 3-4 years later I got complaint that the battery is empty after short distance. I noticed it shows full charge shortly after plugging in the charger (voltage around 24 volts when it shows full!). The lights on battery would show 4/4 (full) but on the bike it was showing 1/4 (empty). I did the same reset again and plugged in charger and now its 1 out of 4 and it did charge to full and it works better.
Thanks for the help. You were right and this happened to my e bike. It just stopped working and showed a voltage of 13.4 v on a 92 v battery. the battery itself was at 84v but the outside connector was 13 v. The BMS was more complicated but the China seller thought I would buy another couple bikes so she asked the technician. I was told to hook up a 12v battery charger and touch two leads. It reset the BMS and everything worked again. If not for this video I would have no choice but to buy another battery.
Hei, gjorde akkurat dette pa batteri til en elemett elvita sykkel. Batteriet er utformet litt annerledes men komponentene er bra lik. Etter resetting tok det lading med en gang. Spent pa om effekten er like god. Sykkelen var kjopt pa coop i norge
Friends battery have different BMS, it has small button type battery on the board it self. It's soldered on the board so it's not really easy to remove. I tried all the steps but it didn't work. I think I'll have to pop that battery out.
Hi! I have a problem, battery works, but it will be lose energy very quickly. I measured voltage from behind and get only 4,3 V. It is the two closest pair, others are not giving anything. With opened battery I find 29 V. I tried your solution, but it didn't work. What is wrong?
I guess you are right. I tried to connect almost dead 9V battery to my bike. The left and right one made the light flash on control panel (in front) even if power was off! Actually the thing what I want to know is, could biltema's ebike work with two 12 V lead batteries? Can it be done? I don't like Li, because I understand the Pb-battery.
Biltema should be sued for selling planned obsolesence products like this. not very friendly for the environment and consumers. I'm amazed if there is no legistlation to force companies to take responsibility for doing this and continuing to do so in the future.
They are doing their best (economically), thay have avoided customs fees by importing their ebikes via vietnam to avoid the 78% import tax! They file all their profits in holland (95% at least, no one is perfect). and this documentary was done in 2019 about their shady businesses: www.svtplay.se/video/21908866/uppdrag-granskning/uppdrag-granskning-sasong-20-biltema-en-solskenshistoria?id=KAB2Vqr&tabs=productionPeriod-8zoydGW-2021

Thanks for great video, cheers from Norway😊
Thank you a big time for making this video in English! Greetings from Finland.

Nice.. just saved my 36v bottle battery! BMS reset worked for me!
The same BMS is inside Cortina batteries, they also have the same issues and can be fixed by reset.
Hi,my battery dead because I didn't charge and didn't used in last winter.how can I fix it
Does it work with normal BMS? Or need the original?
Friends battery have different BMS, it has small button type battery on the board it self. It's soldered on the board so it's not really easy to remove. I tried all the steps but it didn't work. I think I'll have to pop that battery out.
Hei I need this battery I am living in Norway, you sell? Tank you Fabio
I have the same battery, from Norway. But when I press the red button on the outside it wont even blink. Not taking charge
Have the same.
I can't even close it up because its a spaghetti of cables
I have the same battery, but the cells inside are lithium, not Samsung.. How can I fix it please?

"voltage from behind" you cannot meassure since its turned of. You have to meassure in the charging port or on B- and B+
My friend measured from behind his battery and get 24 V, 19 V and 17 V. Why my battery is not giving the same? BTW I am talking 24 V 10 Ah battery...

And it could easily be fixed with a switch I guess
For all countries in the EU, this practice is illegal. Biltema should pay their due diligence for this.
