I second that. I need a dual battery system and can't decide between IBS and National Luna. A better price would help solidify the deal.
The IBS really isn't if you have all of the wires tucked away. it also depends on where your second battery is located, which DB system you're running and so on... I highly recommend the IBS... but that's just me being biased.Are dual battery systems pretty easy to move from one vehicle to another? I'd be interested in a group buy.
