If your original one also has 6 pins then you might be in trouble, if 5 or more are wired up in the battery/controller then it will have comms protocols that sends commands to between each other to communicate and work. Though you new one also has 6 pins, it is a Sans model and I bet only 4...

It looks broken to me as the back is snapped off, also with out it being able to power on you won't know yet if it will work or not. I have had a look but nothing stands out, how many wires are there ?

I would be very surprised if the batteries are 25ah/900wh , it would mean there are 70 cells in side. How much does it weigh ?

:eek: If we all had 250v batteries we would get there before we left and in warp drive too. Ah is battery cell capacity, calculated by how many cells connected in parallel, so a 10ah/36v battery has a working capacity of 360wh. To calculate battery Wh multiply the Ah by nominal battery voltage...

The length is deceiving in your pics, how many cm tall is it. If C5 #8 doesn't help go lower, it depends how the C5 function works on your LCD my one's decrease amps by 0.5% for each digit decrease newer ones's by percentage.

The cyclist I believe counter claimed and the settlement was changed as she was found 50% liable as well, I think it was lowered to about 30K. Also a just giving page was set up to help him and again believe monies donated exceeded the compo amount.

My first thought is the system is closed type system like a Suntour system and needs a genuine Peugeot battery to communicate with the led display and controller. Though the new battery lights up the led display it refuses to remain on, so there is a communication protocol that is not happening.

Can you show us a full pic of the battery, I can't believe for one minute that 25a /900wh can fit inside a standard silverfish case. The most capacity for 36v I have seen for one is 17.25 ah using 3500mah cells. The controller is KT you can adjust the current setting by using parameter C5 in...

He was only found not guilty of causing her death, I assume the police could pursue and prosecute for the bikes illegality ?

Quite stunned he has got away scot free from a court, but as said private action for damages could still come. So what now for users of non legal ebikes if they get stopped or the rating of their bike is questioned, does the not guilty judgement mean it has set a precedence for high powered...

Have you checked the side plate sealed bearing for rough rotation to rule out a bearing screech ? Turn it with your fingers to see if it feels notchy or rough also the same with the planet gears they can be replaced. The 4 key way clutch is obsolete now and was replaced in 2014 or so.

Problem with D/D is it will be gutless at 18a, that's why they like higher current otherwise a 250w geared hub will trump it all day long. Debbie should try the old 250w again if it was hub and set the controller to 18 - 22a and try again with the new batteries. Being dual voltage is the...

Selling your existing ones will likely mean you take quite a hit on them of 50% or more.

The individual BMS should back up and should limit the current draw, though agree a single battery with correct discharge specs would be better for anyone who doesn't understand or know what they are trying to achieve. I myself have had no issue paralleling multiple packs to achieve a specific...

We don't know what type of batteries are being use, if they are soft packs they will have an external fuse.

Paralleling the batteries will double the continuous discharge rate and capacity, a single 30a fuse inline just before the controller connection will suffice for protection. If the draw of 30a keeps popping the fuse then use a 35a one for a bit of headway so the limit isn't being bounced all the...

The Merc vans at work have speed limiter, min setting is 20mph and the van will not go above. The company use telematics to record all speeding and drivers are called to book for any contextual over speed. I predominantly drive with limiter all the time except on dual carriageways where I use...

Tbh for single battery you will likely need a battery built to be able to cope with 30/35a continuous draw.

If the two batteries were connected in parallel they then become one, the capacity and discharge rate doubles then use a 30amp fuse, though a 30a fuse may still pop as it is at just under the max draw of the controller.

The battery needs to have a discharge rating above that of the controller rating by at least 5amps. This the problem with illegal 1kw D/D hubs and power hungry controllers , vendors sell batteries that are not up to the job and they continue to use crappy 5a rated cells instead of good 10 - 20a...
