Powabyke 36v Li ion Battery

[tony6403]

I have had 3years 5 months use from the battery and it is understandably not now performing as well as it used to. It has never produced the distances claimed but was good for about 20 miles if I pedalled enthusiastically.
I have been looking at buying a new one and they are not cheap.
Is DIY recelling the existing battery worth attempting?
Is it possible that the deterioration in performance is down to a few cells packing in and I would need only to replace those?
Have not opened the battery - are they D type?

Youneed to open it up and see what's inside. Which Powabyke is it?

Hello , it's an X24

Your battery is only 6aH, which is why you have a limited range. I've not seen inside one of those cases, but I'd expect to find thirty 2aH 18650 cells. I wouldn't bother replacing individual cells. For me, it'd be all or nothing. The problem with replacing cells in a bottle battery is to find someone that'll weld the tags with the cells in a circle. You need to look inside the case to see the configuration. I think it'll be easier to replace the whole battery and case.

You have to be careful with a different type of bottle battery in case it doesn't fit in your frame. You assemble the holder to the bottle fixings, then slot the bottom of the battery in, which leaves the topresting on the holder, and then you press it down to clip it in. This means that you need space above where the battery sits at the top in order to get it in and out, but sometimes the acute angle in the top corner of the frame doesn't allow it. You need to check carefully that you have enough space in your triangle to fit it.

If you can't fit the above-mentioned bottle battery in your triangle, you can fit more or less any battery you want on the rack, Your bike will still be nicely balanced because you have a front motor.

If your bike has the older brushed motor; and I would think it probably does; then you need to be pretty selective about what you replace it with, as that motor pulls some serious current when going uphill.

If thebattery Frank has linked to is the one with panasonic cells, as is the one on my 8fun kit, then I don't think it has enough grunt for the job; although it does claim to give 24w peak.

I bought a 2nd hand Powabyke x6 for my other half, which has the original small "bottle" type battery, which is only good for 8 miles-ish on hills & 15-20 on the flat. Her controller cuts power @ about 33.5v, which, to me, seems way too early.

I tried the 9ah bottle from my kit on it, with very similar results (8-10 miles on a hill route), whereas it gives 15-20 miles on my bike.

I have tried a 10ah flat-pack cycleasy battery & this is better, giving 12-15 miles, but the killer is that high lvc @ >33v.

In your situation, I'd go for a battery that will give at least 18amps, as that's what the x6 controller's rated at, for a sensible length of time.

I don't know what the newer Samsung celled bottle batteries are capable of, but someone on here probably does......
