I want something a little smaller, but still want some power. I saw some people using the same size, but I can't quite remember what it was. Was it a 51R that is commonly used. . .are people having good luck with them??

 

51R, yes. It will save you 8 -10 lbs. over the stock size battery. You can buy one for around $40 at Costco.

 

Thanks trickshot. . .sounds like money well spent.
