I am selling my brand new braille B2015 lightweight battery. It is about a 35lb. wieght reduction over the stock battery. It has never been installed and is still in the original packaging. Also included is a braille aluminum mount kit also never used. I bought it for my 04 330ci and it is daily driver capable for the e46. For pictures please pm me your email address and I'll send some over. Brand new form Braille this cost me $268. I'm looking to get $175 shipped, basically throwing the mount in for free. Thanks for looking!
