I have a battery Bosch Powerpack 400 from 2020-03, 17000 km distance. It holds the charge nicely but the motor starts to chop after 10km like it's not getting enough power and then it shuts off. I can start the engine a while later and it works again. The battery has done its job I GUESS? Almost four years with 125km per week...
Would be great to see a video with replacement or conversion with LiFePO4 cells. These are hands down the best batteries because although they are slightly less energy dense they will save you a TON of money in the long run with a service life of 8 to 10 years a minimum of 2000 charge & discharge cycles while keeping 80% capacity vs Lithium Ion giving only 300 to 800 cycles meaning expensive replacement every 2 years. Ebike battery sellers don't make many Lifpo4 battery packs because they want you to keep buying batteries over & over every 2yrs instead of every 8 - 10 yrs or even longer if you limit charging to 80%.
Hi and thanks for the video very useful. Just wondering what did you fix in this battery! You used new cells and moved things to it. What was the problem and these cells last for very long time. I found most of batteries problems is the bms not cells unless it's water damaged. Thanks
Good evening. please tell me, I rode a bike in the rain and ended up getting the battery wet. Now it works with an error: the LED strip is constantly blinking. There are no problems when riding when it is connected to the bike. but when I turn off the bike it turns on by itself. when the battery is not in use, the charge indicator blinks all compartments depending on the charge
I just repaired 2 of these batteries. 1 had the pink samsung cells 2800mah. and the other had chinesse GA´s in it. Both batteries had just 1 group of cells completely dead. That .2mm nickel can be welded nicely with the Malectrics spot welder kit. It can even make a hole thru if you use a diesel car battery....
Great video, many thanks, I have bitten the bullet and bought a new battery pack, as I read that the BMS would lose its program when the voltage drops below a certain value. On opening the battery pack (400 type) I found the cells are not well at all…. I do not use the bike in wet conditions so the bms should be ok 🤞🏻 Your video now gives me hope I can resurrect the old one with new cells. Thanks again
Thanks from the Netherlands! We have a lot of Bosch powered ebikes here. I started repairing ebike batteries as a hobby. Did not get an hand on a Bosch battery yet. But on the internet I read that these basterds are bricking itself when you cutoff the power. BMS is then unrepairable. What I see here is that you just migrate the bms from one pack to the other without issues.
Interested in this too. Also, @batterydoctor - how do you manage to get the cell holder apart? I find the friction of the original cells prevents me pulling them apart....
Have a question. I have a trek rail 5 that came stock with a bosch powertube 500. The 625 is also supposed to fit my bike. So I guess the batteries are the same size? Does the powertube 500 just have dead space we’re extra cells go or are the cells on the 625 larger capacity? If the 500 has dead space can extra cells be added the make the 500 into a 625. Thanks.
Old thread but... If the bike can use 625 then the frame space must be longer and there is a spacer which extends the 500wh pack to fit 625wh length space. 500wh uses 10S4P but 625 is 10S5P so has to be organised differently. Therefore, you cannot simply add cells to a battery organised as 10S4P to get 10S5P.
I have 5 of these packs and I've replaced the cells and every time the BMS battery indicator does not light up no output voltage? Does the BMS brick Once you remove the old battery
Also I have no bosch charger only a bench power supply I'm manually charging the pack before installation 42V but I've tried 5 bms but will not turn on
@@Batteridoktorn Thanks That makes sense too some extent. But why do some packs battery indicator work and some do not 🤔 even without a charger present
Is it possible to fix a powerpack 500 that keeps notifying temperature error when trying to charge battery? It also doesn’t give electricity to the bike.
Hi, Many thanks for the video. I have a Bosch battery as shown in the video & I am looking for some advice. According to the Bosch Diagnostic Software the Battery is deactivated with one light showing on the display & the Battery refusing to charge. My question is, if I replace the cell pack but use the original BMS, will the BMS still say it is deactivated or will it allow the Battery to work? Thanks in advance
Hi, thanks a lot for your informative video. Two of my battery led flash! It’s not getting charge! Do you know what the problem is? What should I do? Thank you
Doesn’t this way mean all the current has to pass through those single pieces of nickel strip on the series connections. It doesn’t look thick enough to me. The Bosch design will have that central nickel strip as the main conductor with the cells feeding into it and I can see that central run is substantial. Those zig zags look like they need doubling up to me.
It's not recommended to do it, battery is a dangerous thing. The repair battery doesn't pass any vibration, waterproof, charge/discharge protection function check. It will cause serious problems once any issue happens.
Hi, I replaced old cells in my powerpack 500 with new Samsung 3500 mAh. The accu is weaker then the 4yr old that I have on 2nd bike. All the cells are fine, voltage is good. Do you know what it can be??
I'm looking for a speed ebike. I understand Brose motor has a more open way in using batteries than bosch...? I would like to have the option to buy my own LiFiPo-4 packs in the future, but it seems Bosch prevent DIY solutions by communicating with the battery pack. Would it be posible to hack a Bosch battery to create a connection for an external power pack? This way the communication part may still work, but actually using external power. It looks anti consumer to me, those 500W/h powerpacks are way to expensive, and you get allot more charge cycles out a LiFiPo-4 pack.. I know, because I used one for almost 10 years before it was finally done with it's capacity. They really last 3000+ cycles! And are cheaper than the Bosch packs.
Thanks, i heard similar stories about Bosch. However that has NEVER happend to any of the Powerpack batteries we have worked with. I guess the eprom can be programmed different on their other battery lines like screwdriver batteries etc. Of where have you heard that? From what i know its just a rumor.
How is it possible that vanmoof cycles achieve 500wh with 30 cells instead of 40? Also one important step is missing: how do you get to 0:11, or how is the case opened?

I got plenty these battery packs with faulty bms boards. And then, repair is impossible if bms is faulty. No replacement bms board available to purchase, I'm afraid.
Yes, same hear. Dont know if they can be reset but we plan to clean with ultrasonic cleaner and maby some will work again. Hopefully. Older bosch have been cracked in both china and germany and there is also an activator for gen 2 bosch batteries but for whole BMS we will have to wait i guess.
Nice job man. One question. If in the future new and better cells will become available, do you think the electronics of the battery will let us use the full capacity of the new battery? thx
I can probably answer that. So long as the voltage of each cell stays the same, higher capacity cell should work with existing BMS. The BMS may not accurately show % level in such a case.
so can you use a normal 36 volt 10 amps bms in these batteries as i dont see why not there is nothing speciaal about thjm, if not have you got a link to where i can buy a replacement

Thanks for the video! I have a Powerpack 500 with a faulty BMS (apparently as the LED stopped lighting). A friend can give me a 400Wh Powerpack to get the BMS. Is the 400Wh BMS compatible with the 500Wh one?
Yes, there might be different version but they should all work the same, except the old ones with from the classic series with a different connector. They are different.
Hello. So if the bms is in working condition it can be unplugged and put to new battery just like that? I allways tought that the bms should not be powered off that youll need a powersupply inbetween the switch from old battery to new. But seem like thats not the case? Only thing is that if i put new cells to a bosch powerpack i cannot increase the capacity becouse of the bms limits the capacity?
Bosch say max load on 500wh pack is 20 amps so a fully charged pack at 42v can deliver 840watts for a short while without damage or a depleted pack at 35v only 700watts.
good job, you make it seem so easy. i can solder and spotweld. maybe i could revise my battery to when she is done. also a bosch 500 where did you get the cellholders? did you 3d printed that?

@@jonathanmaus7125 They dont brick. Never heard of it.
Hey , nice job. Can you disconnect the BMS from the pack ? Will it not get in safety mode when there is no voltage on it ?
You may not disconnect the BMS from the pack, I did it once and ruined it
MEK (methylethylketone) will melt the plastic burrs, and a heat gun will make the rough plastic shine. Not too much of each.
You are the doctor, what job 👏🏼👏🏼👏🏼
The way you have the cell strips configured it will not balance well.. you should put two more strips on the cell groups.
