To me it looks like condensation damage. You drive in winter for longer period lets say 3-4 hours, then go home and charge. Charging heats up batteries enough to condensate.

Where did you get the replacement cable? I'm having trouble finding a 5.5 mm dc jack that's rated for 54v

These things are a huge fire hazard. I'd love to buy batteries from Ali since I buy so many things there. But I'm afraid it'll take many years for them to get to the right standards for such dangerous goods.

The chinese have nightmares from the stick of truth

I have bought a 48 V 20 amp hour battery from Audi express my bike runs on a 36 V system. It shows it on KZbin that it could be that it accepts a 48 V battery mines works for good for an hour the new battery and then it just shuts off when I would put a charger in unplug the charger for five seconds And power will be fully back on again so I don’t know what the situation is. I don’t know how to test this new battery so all I got is my old battery the new battery I don’t know what’s wrong with it. I don’t know if there’s something wrong with it. I don’t know how I can fix it. I don’t know nothing I just got this new battery that I need help with Anna. Yeah if there’s any advice, I don’t know if you can thank you.

Hey, do you know where i could by a battery for a Navve N65?

I also need this battery. Willing to buy one if anybody has it

Yes outlet first and also just wait a few seconds before connecting the charger to battery.

Burning smell with water damage - ah ok - yah should buff out np! lol smh

Wow, thank you so much for your recommend for our battery assemble parts. You are the best.

Overkill. You could have just cut a1/2" slice over the fuse without reverse engineering the whole batter waterproofing blue plastic

Question, if you have 400Wh at 36V that means around 11000 mAh right? My powerbank is way smaller and even my 11860 battery of my vape is 3000mAh at just a single battery. So my question is why are there so many batteries inside?

Thanks for sharing this.

Liquid Crystal Display Display 🥱 It is called tautology ...

Those snips are some of the most common on earth.

AliExpress is full of fakes and they refuse to refund

Hello, I have a question. I revised my promovec 50638 and now the display says my battery is empty although it is 39,5 volts. All the sensing wires are working: 3.9 volts per pack. Do you have a way to let the display show that the battery is full? Thanks in advance!

Much interesting market info here, however not the right video for someone looking for how to capacity-test a cell.

Thank you for sharing your information and knowledge… 😉

Get. A. Dremel.

Hi, where can I buy that charger?

Hej man i need a help i loose my 2 key batery cylinder in ridstar pleasehelp

Battery Dr. I have one these. The unit turns on and has charge. My problem is using the charger I have doesn't charge the unit when plugged in. The transformer has an indicator light, green when full/disconnected and red when charging. It is only green. I made sure no debris in the connector and feels like it seats well. Can you tell me if I have battery problem or charger problem. Thank for your time. Your video is well done. I love the passion and enthusiasm.

Planetary gears 🤔

Können Sie meine Platine reparieren?

Very interesting

Looks like dynamite from the 80s

Or 5S8P ?

Hello, i have same battery, i want to ordrer new bms for it, can you please help me to find the best one for this battery ? this is 10S3P battery ?

Thanks for the tear down, I have a bosch system on my commuter, I have been looking at a conversion kit on another bike, and this has convinced me that's a brilliant idea, rather than committing to another bosch which can't be serviced DIY, however I will add, my bike from 2018 is still going strong, after one early motor failure, it was fixed under warranty no issues since.

Hi! Thanks for the video! I have several different power stations, I wanted to test them with Electronic Load Tester with the USB-C cord, the load stops at 15.9W+. What's interesting is that when I load the stations through the same port and cord, but with a laptop, 70-90W goes smoothly. I can't understand what the problem is and how to load the stations through the type-c port using the Load tester more than 15.9W?

Note: it is 18650 3.7v battery as shown in 1:59.

Doid for kugoo G5

omg. whatta hell is that :)

Can I guess how for my battery?

what's that gonna do 5 miles ?🤣

How do can u take the the wires from battery charger port 4 pin (36v 418 wh) and connect the wires to a battery charger

Language! I can’t even watch this vid with my five year old hearing you swear. 😮

Good ! Do you know if the Qwic motor can work with another controller/battery ? And if so where to purchase them. Many thanks !

Hi man, do you have experience with NORCO battery (Trend power technologies), i replaca a NTC broken and now this BMS are like NG (permanent failure status) have good SOH to discard repair it, if can help will be great! Thanks

so im just here trying to figure out how to modify my battery pack LOL

Hi. What spot welder are u using. Injave Docean and i have troubles welding pure nickel. Plated steel works woth fifth of max power but pure nickle can't do good with full power.

im thinking of upping the voltage a bit for a bit more power by putting 8 batteries in series instead of 7 but im afraid the controller won't like it, what do you think?

Now why would you compare this POS charger to the grin. It’s miles and miles behind it’s not even in the same ball park lol

Hi I’m wondering can you attach a Bosch battery to a Shimano steps e6000? Thanks hope you can help my friend 👍🏻👍🏻👍🏻

I also adore Great Scott since several years and I still can't figure 1/4 of what's happening electronically...

very interesting, I personally use the NIMH charging function at 0.5 amp on a Imax B6 to revive cells under 2v. But your method is way safer I think !

OMFG this is soooo sketchy ! You should try to put it in a safe area and overcharge it, just to see if the technique is secure...

such a waste of time for 5 or 6€ worth of 18650... I used to do like you several years ago, I now throw everything away when I have cell under 2v...

Gay colors😂😂
