Gadgets that make it more comfortable, like fridges and other things that help you record those special memories like your digital cameras. But a lot of those devices, well most of them suck battery power and that does create a few problems if you relying on one starter battery. So how do we solve those power problems.

Well it’s not just as simple as fitting a second battery, although that does soul part of the problem because you increasing the capacity. But if you simply install that second battery or that auxiliary battery without any management system behind it you, could still be in the same trouble as you were beforehand. Because what will happen is when you plug in all your electrical devices, it will drain down both batteries. So your start a battery and your auxiliary battery and you won’t have enough power to start your vehicle in the morning.
