while the dealership has my SXS after the oil leak... they now tell me the battery is dead and needs replacement.

their price is $244.00 plus 15% tax.
the part number i was given to outsource is a YIX30L-BS

called 3 local ATV dealerships.
i got for that battery number proces from $222 (CFMoto dealer in the next city) to a low of $163 but there is a designator missing off the battery at that price... the BS is missing.

So i have 2 questions.
1. I'm not sure what that BS signifies on the battery.

and

2. What are  drivers using in their Uforce?  When I go to look that number up on the internet it says it does not fit the 2015 CF Moto 800 Uforce.

Thanks in advance

I don't know what the "BS" stands for but most people are just using this one on their Zs and Us as replacements and they are all working just fine. It will be what mine gets when the time comes.

According to CFMOTO the exact battery used in all models is in fact the YIX30L-BS.
the difference between the BS and non BS is the non BS model is preloaded with acid at the factory. 

Amazon in the link would be incorrect. 
i wonder how many batteries these resellers have lost?

The ones I ordered didn't come loaded with acid, simple process though. I think I spent about $160 buying them online

I believe the Yuasa is a good battery as well.  BS stands for battery sealed.  No big deal to add the acid to it after shipped.

i was able to go to Canadian Tire and find a battery.  direct fit.
