Can anyone explain in the simplest way , how I would know what the continuous amp amount was on my battery ,, I have 48v 15ah kugoo G2 pro scooter battery ( homemade case) the controller is 36/48v sinewave thing 25a ( nothing special) small black box and I think it's 1000watt voilamart wheel allthough often hits 1200 ?? Sorry if all this sounds dumb, I've done 947 miles with this setup with no issues ,, was just wondering what to set the Amps to on the screen currently it's on 20 and how would I know what the continuous amps or what ever the term is, again... So sorry
 
If you can identify the cells that the pack is comprised of, it's simple math to determine the continuous current of the pack (when new). That rating will degrade over time as the pack ages. If you don't know what cells are used, you'll need to open the pack to determine the part numbers stamped on the cells.
 
Your battery or its BMS specs should include a maximum drain rate in amps the 3rd relevant metric after voltage and capacity in amp hours.

if not on the battery case (probably molded/embossed) check online for its detailed specs.
 
Yikes!! I did a cursory google and browsed a small selection of ads for similar batteries and None specified a max drain rate or any details on the cells employed. - if a more detailed search online also fails to provide results you can always crack the case and split the heat shrink wrap to expose 1 or more cells and their ID label which will provide you with whats needed to google the datasheet for the cells which will include the max drain rate for each cell..

Then look up and double check if its the number of parallel or serial connections thats used to multiply by the cell rate to get the pack rate.. (iirc its serial so a 10p3s pack with cells with a 10a max drain would have a 30a max drain)

Then remember to give the batteries a break and provide a 20-25% or more overhead when setting your max current..

Yeye like I said all works great and hits 33mph , smooth build up , I wouldn't want to tear it up just to find the info , but also I couldn't find ANY info just one says 800 watt scooter, but cost 250 online for the battery I only paid 40 £ and thinking to good to be true atm ,
 
Almost certainly made with generic Chinese cells. Likely the cells are rated for 2500mAh and about 5A max discharge. My guess is it's a 13S6P pack. That would be 48V, 15Ah, with a max discharge of 30A (when new). I'd use a controller limited to 25A or less.

Yeah haha so I should leave it exactly how it is 😁
 
See i got my serial and parallel mixed up above, whoops.. ;). Yeah if its not broke dont fix it..
