Inside a FAKE Hailong battery pack! AliExpress Scam...

[@driewiel]

Maybe there are more minutes in a Chinese amp hour because it's a big county?

[@EbikeRepairs]

This is possibly one of the best comments I've ever seen, thankyou.

[@sankaplays3098]

Just a simple translation error. Am I right ;) For me, the blue wrap is always a dead give away. Why hide the cells if not intentionally?

[@parkerwhite4902]

I like that your video for me has a sponsored add for Ali express lol

[@EbikeRepairs]

😂😂 they're listening!

[@republicfryslan]

Hahaha even now😂

[@hipupipisakula3498]

Good for exposing them👍👍

[@EbikeRepairs]

Thanks dude 👍

[@seanobrien499]

By Circuit board I mean BMS of course thanks love the content

[@EbikeRepairs]

Thanks!

[@GBPaddling]

Some on sale on Ebay now purporting to be 50ah and even 60ah from a case that size, ha ha.

[@EbikeRepairs]

Seems legit 🤣

[@liammcgirr1778]

Where would you recommend getting batteries from? Mines not holding power as good as it used too.

[@EbikeRepairs]

Reputable supplier! Yose power/Bmsbattery/greenbikekit are known. Or a battery builder local to you.

[@user-nk5xi6lj6f]

Ive got a large ebike battery in a similar style of case which i can hear the pack move around inside case over bumps, also hear it if i remove the pack from bike and turn it upside down or certain angles side to side. Am i able to open the case and pad it out? Not only is the noise annoying but im paranoid its going to eventually wear or damage something, causing a short etc... Its not a huge anount of movement, but its enough. I need to replace the lock in the pack anyway. Thanks

[@EbikeRepairs]

So I can't encourage you to open a lithium battery pack - but if it was me, I'd sort it out before it caused a problem. Eva foam tape is your friend.

Who makes the best 52v battery for making an e bike

[@brikfiend]

Hi M8 .You mentioned you tested the AH's of the battery . How can I do that please ?

[@EbikeRepairs]

I have a capacity tester, I did a video about it on the channel if you search :)

[@JDara1]

How did you spot fake one? I am thinking on buying from aliepxress too from Titan West Electric Bike Store seems to be 314€ for 48V17,5Ah or 702€ for whole bafang converting kit

[@EbikeRepairs]

The customer brought up that it seemed too good to be true price wise, and it was!

[@craddlerobber1]

I was hoping you would show how the wires are connected to the battery....I gave a robot vacuum, they make the packs, but none ,for the connecting end on mine

[@EbikeRepairs]

Sorry - I've got lots of other videos, though!

[@seanobrien499]

I have a bad circuit board or female 5.5mm barrel style input port. It literally sparked when I plugged in the ac adapter. The battery has no fuses. The battery will not accept the charge says green. I can charge directly on the terminals when I took it apart so the cells are good. Any idea where to get the battery charge controller circuit board? The stamp on the bottom is SP-M13-016-A01 / SIZE:80*38*1.6MM / DATE :2016-05-27 / UL 94V_0 ROHS. Google gave me no results amazingly enough. Thanks in advance for your help & content!

[@EbikeRepairs]

Hiya quite possible just need a new generic BMS. You HAVE to check the cells are all in balance though, each group needs checking for equal voltage. If all ok Then you can just replace BMS and off you go (provided no smart functionality)

[@seanobrien499]

Yes all the cells are good I recharged the batter using just the terminals. Where can I get a generic BMS may I ask? Thanks a ton for your assistance

[@EbikeRepairs]

But you have to check each cell group individually to make sure! AliExpress/eBay would be easiest I suppose 👍 if you're in the UK they're on my website :)

[@kenttran5289]

I also got one like this; rated as 20AH but feels like 12 to 15 for 200 USD in 2021. Another problem is the power switch on mine do nothing; it's always on and the USB port has power but shutdown after a few second of power draw. Don't buy from unknown store.

[@EbikeRepairs]

Hard luck! yose poser is reputable :)

[@johnmorris3776]

I would not use anything sharp on a lipo battery unless you want to see fireworks.

[@EbikeRepairs]

Unfortunately I can't open it another way - just be very careful and have a bucket of sand/large outdoor area available if needed.

[@tonypaddler]

... and someone with a video camera on standby too, think of the YT views 😬🤣🔥 ​@@EbikeRepairs

[@PerryLevy]

How do you test the Amp Hour on the battery?

[@EbikeRepairs]

I have a battery capacity tester ! It's very handy.

[@PerryLevy]

@@EbikeRepairs Ok, Ill have to get one. Thanks!

[@PerryLevy]

Any recommendations?

Annoying isn't it!

[@chubbyelf5094]

Were you able to get a refund? This could be a good strategy... buy obviously-fake batteries and submit claims on them

[@EbikeRepairs]

Its a customers battery sorry I don't know.

[@jeandaspry4323]

Thinking about it... Did you try it? 90€ for 36v20Ah or 150€ for 48v30Ah... Even crazier, some are sold by 10+years old stores with 90%+ rating, I dunno how they do it, other than refunding every angry customers, and even then...

[@omargdottin]

That case is 36v or 48v

[@EbikeRepairs]

48v I think

[@luchackcadler1438]

All battery on ebike are same lithium battery, no other entity battery. Unless some battery mixed fake sand battery. That's the time you freak out.

[@EbikeRepairs]

They're not all the same! Some cells are better than others 👍

[@EbikeRepairs]

They're not all the same! Some cells are better than others 👍

[@thedanyesful]

Just because it's lithium doesn't mean it's the same.

[@bigcatsliontiger]

thats 48v 10 Ah battery

[@EbikeRepairs]

not quite!

Ringo !

U want cheap and Quality no way I us this battery 48v 30h it’s no bad 160£ I do my job 8h

[@EbikeRepairs]

Mhm

[@Asfanboy1]

Mine is getting warm and it's winter

[@EbikeRepairs]

uh oh! possibly not high drain cells, or high resistance connections!

[@AntonFetzer]

What exactly was the problem with this battery then? Appart from unbranded cells it looked perfectly fine. My battery looks the same.

[@EbikeRepairs]

Rated capacity Vs real capacity was totally bogus. I can't recall the figures but I think it was supposed to be 15ah and only around 5ah

[@AntonFetzer]

@@EbikeRepairs My battery has a sticker that says 100 Ah, but I obviously know it's wrong. On full throttle I get maybe 10km of range. It was only 50€ including the charger and shipping, so I can't complain.

[@isavv_]

@@AntonFetzer50€ should almost be the BMS alone.. not the whole pack.. I wouldn't trust such a cheap battery..

[@AntonFetzer]

@@isavv_ well it works. 10km of range for 50€ sounds like a good deal for me even though the manufacturer lied about the capacity.

[@isavv_]

@@AntonFetzer Yeah but where they cut corners will be my concern..I would open the battery and check myself if everything is ok just to be sure.

[@donho1776]

How about some testing instead of just a skeptical opinion. There were no significant visual negatives, just suspicion because of low price.

[@EbikeRepairs]

I did test it off camera - at 36 seconds I tell you that :)

[@vorkev1]

I do not beleve it cus I have a 48volt 23 ah battery same sells and it's actuly a little higher

[@EbikeRepairs]

This one was fake, I tested it
