Looking to charge your Batt Pack Pro on the go? Our high speed vehicle charge kit wires directly to your house battery or starter battery, allowing you to charge at a rate of up to 700W. Whether you’re hitting the open road or on the way to the job site, the charger automatically kicks in when it detects voltage over 13.2V, which would indicate the engine is on and running. For peace of mind, there is a backup ignition circuit for additional discharge protection. Available in both 12V and 24V.
