Title: Universal Power Group UPG Batteries
Post by: Gregski on June 15, 2009, 01:02:08 PM

The UB12500 Universal Power Group UPG batteries for approximately $100 bucks each sound pretty good. They are sealed AGM and claim 50 amp hours and weigh only 39.6 pounds. Also they are compact the specifications on this battery are Length 7.8 in., Width 6.54 in., Height 6.75 in.

I already have the Mars ME0709 72volt 300amp motor, and plan on getting the 7245 450amp Alltrax controller.

So for half the price of comparable Optimas can you tell me why I shouldn't buy them?

whats the max continuous discharge amps? and how much does the capacity decrease when they are discharged at this rate?

Batteries are not created equal, even if the spec sheet says so, I have gone cheap before and got exactly what I paid for  :(

I now believe in paying for the batteries that have the highest satisfaction rating among the users  :)
