Battery ID

[Caprisvo]

Can anybody help me ID this battery, and specs?

I bought a second hand kit from a person on offerup that didn't know much about it, other than it was a golden motor 48v 1000w rear hub drive. It is an older Golden motor kit, but the wheel/tire looks unused. I was able to get some details online for the hub, as it has a number stamped in it.

The battery I am not able to find info/specs on.
I've found multiple batteries with different specs online that use this same case.

Inside it is constructed with 39, 26650 cells with no numbers or markings on them that I can see.

What I'm most interested in is the AH rating.
Anyway to tell from the info in the photos?

I would say it is less than 15ah with the info shown. Any 48v battery will do for a GM. If you must have the same style case then just get one that has one like it.

I just ordered a Voilmart 1500w rear wheel/hub. Do you think it will be sufficient for it?

To get to 1500w you will have to have a controller set to at least 32A @48v. That battery might support that at full charge but will not sustain it as voltage drops.

A controller is coming with the wheel as well as other parts of the kit so hopefully it will do the trick. Looks like I may be shopping for a battery then though...

Any suggestions?
There is a sea of offerings out there for sale in the spec range you mentioned, and I have no idea who/where/which are reputable/decent quality/good value.
I'm not married to the design I currently have.
I'm open to different style configurations, and would actually prefer one that I can mount on the lower frame bar.

Thanks for the help by the way.

Why not send an email to the one provided on the battery with the pics?

Reach out to @Jenny Mao .
I’m certain she’d help translate.

What does Golden Motor say?

What does Golden Motor say?

Well, to clarify it was a "kit" bought from a guy on offerup which knew slightly less than me (me=typically just enough to be dangerous ) I'm not entirely sure the battery came as part of the kit directly from Golden Motor.
The wheel was branded as Golden Motor, and the controller looks like an earlier version of what I see on their site now as one of the controller options (controller).
Battery is not shown on their site. They currently show only LiFePO4 options, though some in similar cases.
It is enough of a possibility that maybe I'll reach out to them...

JES2020, I did email the address on the battery last night, but haven't heard anything back yet.

Well low and behold!
I little more digging on Golden Motor site reveled a PDF for the motor controller that is the same as the one I got with the parts (with exception of labeled part number). It's from 2009, and has a picture showing a bike with my earlier style hub, and the same battery (at least case style) as I have.

I may have a complete Golden Motor kit after all.
I'll contact them

Thanks for the push towards logical reasoning!
