how to revive a hoverboard batteries that won't charge 🤔
Hi my battery is different I wish I could send u to see it
Going to give it a go tomorrow. I haven't got a stand alone power supply but i can rig up a direct negative from the charger which should achieve the same results. If it doesnt all go pop in my face I'll let you all know if it works. I'll prbably set it up in a sand box with remote wiring coz i dont trust L Ion batteries. Here's a thought though. If the BMS is the problem, as it is on most dead L ion batteries, why not just short across the negative input and ouput terminals of the board, thereby bypassing it and achieving the same objective? I'll give it a go tomorrow. Update. My battery pack has a completely different layout to those shown and, although the led on the power pack did go red, the battery didn't take a charge so I'm done with it. Scrap bin time.
What is that device called and where can I get one?
It’s a regulated power supply
Hi thanks for the interesting video. I’m about to try this with a handful hoverboard batteries, but I was wondering if it’s applicable to them. The case is that all of them cause the standard hoverboard charger to turn its led off, when I just plug the batteries in a working hoverboard and use the standard charging plug. It feels like the charger led turns off because of a short circuit it encounters, but the batteries are fine with regard to that. They only dropped to as low as a few volts, all of them. Is that too bad or could they still survive with the trick. And is the led turning off just normal due to the way I ‘test’ them? (Ur doing it straight with a psu) Looking forward to your reply!🙂
Hi, how’s it going? Thanks for watching my video. What do you need to do is find a label or know the nominal voltage of the battery. Normally the Hoverboard batteries are 36 V. The batteries have to be brought close to 36 V for the BMS to do its job. So you can charge from the main terminals of the battery pack At 36 V and low amps . You must monitor the voltage all the time and the heat of the cells. The voltage will normally climb quite quickly. Hope this helps be careful. It is quite dangerous. Thanks, Rouen.
Thanks very much. I woke up 2 batteries till now. One this evening which is still charging. With the first one however, the hoverboard turns off when accelerating fiercely. My theory was that the battery’s voltage drops too far upon heavier load, causing the bms to shut down. When you plug the charger in for 1 moment it turn already on again. If that theory is correct, it’s probably because of the battery having decayed during the time it was around 20 volts? (Which means I would have to replace an unknown amount of cells?) thanks, Harry
Worked for me BUT I was really kind of surprised with the size of the spark that woke it up, I took a line fight off the Negative charger wire. I have also found out that after doing it the 36 volt charger still woud not kick in so I tried a 24 Volt Razor brick with the same connector and it showed red and after I left it on for about 10 Minutes and switched back to the 36 volt charger it worked. Thanks for the negative shuts things down tip .
what about a 25.2v hoverboard battery?
The voltage on the sticker should be the nominal voltage. Empty. You can work out the voltage by counting the cells
hello, what current is needed to wake up the battery?
Hi. The current is only 1 amp. 42 v
@@rouenwucherpfennig2524 what if it's a 36v battery
@@viktor_baek_a A 36 v battery. Is 36 v empty and 42 v full. Charging voltage of 42 v
Okay thank
Full of 18650 cells. Hmmmm.
This has worked for my battery, thanks. :)
You're welcome! Glad it helped
