I will pop out again for measurements but here are the arrangements- keep in mind this is a small frame as I’m 5’3 - the old battery plus case for the controller is about 35cm.

I’m currently on a kwak er-6 for commuting - not as fun as other bikes but a real workhorse that I cannot kill! just for reference and for anyone else searching these forums, everything VFR400 said is true when you strip back the plastics! Just need to relocate the controller in a box somewhere and match the rating/fitting

that’s what I was hoping to hear . . . I shall have to strip it down this weekend. As a side note, I used to have NC30 UK VFR400 - I used to love that bike

Hi all, Apologies if this is a repeat - I did search the forums before posting but only found reference to newer models and was not sure if this was relevant to my case. My battery, predictably after nearly 4 years of a hard-life, has lost a lot of capacity. I am inclined not to replace my bike as I have, over those years, replaced many of the components and upgraded them during this time (including drive train, front forks, even the hub motor etc.) The bike now rides really well and given the life it will have (thrown on to trains and between 50 miles to 100 miles a week) I don't really want to upgrade etc. I thought replacing the battery would be straight forward however I cannot find anywhere that has stock of the exact type. I believe it is SF-06 style battery, the motor is a Bafang BFSWX02 36V 250W rear hub motor. I am relatively handy but inexperienced with e-bikes, I happily upgraded all the bike parts myself and service my car and motorbike myself. I have experience of wiring things like Raspberry Pi's etc. so I am not adverse to a bit of DIY. I thought, before I start stripping bits down, I would ask the advice of those more experienced in this realm than myself! My questions are: Can I replace this battery with something (just for example) like this: https://batteryempire.co.uk/batteries-for-ebikes/3169-green-cell-e-bike-battery-36v-13ah-electric-bicycle-li-ion-down-tube-with-charger.html?gclid=CjwKCAiAkan9BRAqEiwAP9X6UfXE9vmuywla1ZSgRhtp2pha36-o8ef4E9heJRK9g54a7pqh8pyQixoCGpkQAvD_BwE - I don't know why but I have a feeling the controller is built in to the battery holder on my bike - again, I could be super wrong about this . . . If I needed to buy a new battery and controller etc. can anyone recommend any for this motor? Has anyone found an SF-06 style battery and successfully fitted it to the age and model of bike I have? Links would be massively appreciated. I don't want to get the battery repacked as the holder on the frame has some damage, I could probably fix this with some plastic weld but really wanted something new, if possible. Thanks in advanced for your advice. happy to provide photos of any parts or pull things apart if that helps!
