Hello I am trying to replace a a fuse board for n a Bafang battery 48V 15Ah 720W, battery is not charging, but it has some charge left on it. My question is where can I get the replacement part (fuse board)? currently there is 29.67V coming out of the fuse board. Can I bridge the fuse? & voltage out of the charger is 55.2V.
@@monchy25 you mean the BMS? if you're in the UK I can do it for you, £80
It looks like you are an expert, but unfortunately I am in 🇺🇸 USA.
Is not the BMS, it is a proprietary circuit fuse board. I am replacing it with a simple 5A line fuse.
43.8V is 12s lifepo4 cells.
@@Sopheris I agree, but these weren't lifepo4 cells in there originally! Unless when it was 'upgraded' by the company they changed the battery pack... Weird...
I'm glad you use a drill to take all the bolts out, cheers.
You bet
Super! Its working again
@@francofranco1652 welcome
Is chamrider trustworthy?
@@AvaComans I don't think they use name brand cells, but not inherently bad
Are you from UK
Yes 🙌
Hi thanks for video I'am just about to start my own replacement so every piece of information is super important for me thank you ! 🙂👍
Glad it was helpful!
Hi Dash, love the content as always. Am I right in thinking that if I install a variable pot resistor between the throttle signal wire and the controller, I could adjust it, so the throttle would only propel the bike to a legal 6km an hour. If so, any suggestions on the pot would be very welcome. Thanks, Mark.
@@markwilkinson4428thankyou! I believe you could do that yes, throttles operate on ground, signal and +5v, the more you twist the throttle, the closer to +5v you get . Real world they seem to start off 0.5v - 4.7v from measuring them, you'd want to limit the signal voltage to a lower voltage. Keep in mind that the nature of having it be adjustable at all may well make it non road legal - it's a grey area!
@@EbikeRepairs Thanks Dash. On the resent program made by Panorama, they showed a cop stopping a guy on a 250watt bike, The cop lifted the back wheel, and because the throttle drove it over 6km an hour he confiscated the bike. So I'll make mine so it reverts to "Legal" every time the bike switches on, via my remote alarm switch.
@markwilkinson4428 better safe than sorry :D
Someone mentioned they used an old laptop charger! Does it have to be 35v .5 amp or Higher? Please help! Thank you!
Sorry I can't help out here, this is what NOT to do!
@@EbikeRepairs can you please tell me what power supply not to use? Of course I won’t use it and won’t do anything with it.
@@posplaytime801 amzn.eu/d/0rFnKDr I didn't use this exact one!

Can anyone please share what charger they use.

hello, did you find it? I, I have the same problem as you if you have any information I am interested. THANKS
@@JimmyFellous haven’t yet but I think Amazon has one 0-60volt .5 power supply for about $70. I think this is what they are talking about! I just wanted to be sure before buying one.
Hi mate..it is possible to change batteries on a carrera ebike with suntour motor?planning to change into bigger ah..
@@DIEGOruiz-mr2if it depends - old ones with the led display, yes. New ones with the LCD display, No
@ ive got 2.0 with a small lcd display..is there any option to put bigger AH batteries?
@@DIEGOruiz-mr2if small LCD like the oled that's the same size as a KT LCD4?
it's a wonder you havent caused a catastrophic fire with all those rings on!
@@andytipping70 they're ceramic / shiny plastic, it's fine :)
Hi @Ebike Repairs, is Cyclotricity a good quality e-bike conversion kits?
The motors are fine (bafang clones for 250w and 9c clones for 1000w) the controllers are fine (KT controllers) but the 250w kit batteries use no name cells and are prone to early failures, the 1000w battery packs seem fine and don't have too many issues

@@289kman the wau bike will take just about any 36v battery of your choosing! 😁
@@EbikeRepairs the wau battery is 10amp and 36v does it matter if new battery has more volts and amps?
@@289kman keep it 36v, more AH won't matter
Hi, did you put any packing in the casing, as the battery pack you took out was double the size of the one you replaced it with. Surely it would rattle around without packing materials?.
@@malcolmdiamond5681 yes I did! Lots of Eva foam :D
Can i also charge it through the BMS by bypassing the BMS ?
No, If you bypass the BMS it isn't using it
T es un génie mec merci 1000x
@@thekalash87 I'm happy to help :)
Obvs they were below nominal, I've found charging them to around 3.5V with a smart charger set to NiMh or NiCad works (connect directly to the cells, bypassing the BMS obvs). Then finish the charge on LiFePo4 setting (the BMS will pick that up) or the charger that came with the scooter. There will be a reduction in capacity, & this doesn't always work, but I've had a lot of success with this method. An interesting look inside a TGV, they've been around a while.
@@skysurferuk you could technically do this, but the cells form dendrites inside them, a chemical change, that isn't reversible, and this really increases the risk of fire and danger, plus high IR etc. I just wouldn't be comfortable putting a suspect pack like that into a Customers house - perhaps with one cell for a flashlight or something it would be fine, but a whole pack - I just wouldn't be happy unfortunately!
@@EbikeRepairs yes.. tooooo high risk if fire
sent you a text on whatsapp about a battery i have that needs looking at , is that still your number?

hi i was just wondering as i might be getting a cheap surron thjat has this hall sensor error would you think this is the same problem as yours and how much would you roughly charge to do a job like this on a surron motor thanks
Replace the hall sensor yourself, or if its just the magnet then use some loctite to re secure the magnet 🧲
Testing, dropping out the motor, reinstalling, cleaning etc. will add up, maybe £60-140 depending on how smoothly the job goes! (Stripped/seized bolts etc)
@EbikeRepairs what would be your opinion/what you think this could be, so I have a 2022 surron, that keeps cutting out and in, new hall sensor, new throttle, and it's only done this since heavy rain fall... please and thankyou 🙏
@@ryanallen3704 no errors on the display? Quite possibly a controller - you can find cheap ones on marketplace for £100 sometimes, buy it, swap it, if it doesn't fix it you have a spare or just sell it on!
@EbikeRepairs nope no errors 😭 and yeah I might just have to do that, not a bad shout tbf. Thankfully my brother left his here all week, I might have a little swappy swap and see what the culprit is! 🫣 🤫 🤣 thankyou my dude 💯👌
You probably saved me hundreds thanks
@@hsmall2424 you're very welcome 😁😁
so.. keep the case and put in a new bms and new cells.. maybe even possible to increase Ah (bigger range)...
@@dg9bfc yes, that's exactly what I did :) happy customer!
15th week of 2014 maybe?
Ignore me, jumped in too quickly. Another great, useful vid, thanks mate.
No worries 😁😁 thanks for the feedback it's really appreciated!

@@MiniLuv-1984 this one was from last year but scary what can happen inside a battery without seeing it!
Hi m8. Need to ask a question. Could I walk into a bike shop with a new ebike battery and they can fit it on the bike. Or would I need something else coz I've seen different batteries with different wiring etc.
Most shops won't do it, I think you'd need to call ahead and check it's something they work on! Halfords for example don't usually do electrical work on bikes they didn't sell originally..
@EbikeRepairs it's ok. Got it done. I have 18.2 ah on it now. Awesome range. 👌
@andyhumphrey9351 brilliant stuff
there are reverse screw extractor tools for stuck or broken screws. you get them for like 5$
@@Tethysmeer agreed, still a pain in the butt
Almost like a solenoid
A little bit!
Deserves one comment at least ..........
Thanks :D
I can't believe that you work with six rings on hand- doesn't that mess up your dexterity, or risk an electrical shock?
@@mindgames11 honestly I'm used to it now! They're ceramic (aside from one, now) and aside from being unable to hold tiny parts (because my fingers don't close together fully with the rings on) it's fine :) dexterity is no less than usual, I think
Thanks for this! I take it this can be done even if the battery is locked to the bike?
@@archiepuffin6843 you'd have to pick the lock, perhaps, I'm not sure
