Battery relocating will allow me to keep the main battery in the boot so I can have a full ICE in the car running but then it's all wires and relocating that can be a pain in the arse.
Lightweight battery sounds easier as I already have the small mount to completely tuck it away (where the resonator box would be) but then how long does small batteries last? Can you have all your ICE running in the car while the car is on? Does it need to be charged frequently as sometimes I don't drive my car in over two weeks.
Thoughts?
