A Tank Battery is the perfect tool to help your carputer survive your vehicle's inital turn-over / "crank" stage. When you start your vehicle, the ignition system asserts all of its power into the engine starter motor. As you may have noticed, it draws all power away from your inverter or DC carputer power supply; and as a result, your carputer resets, powers down, or dies. A Tank Battery can be used easily to protect your carputer from this inevitable phenomenon. Dashwerks is an exclusive distributor of this great [extremely reliable and affordable] battery. You won't find a price like this anywhere else.
