Having previously reviewed the RAM 1500 in 2020, we recently took the chance to get behind the wheel of the latest addition to the series - the RAM 1500 Warlock.
Equipped with patented Rapid Recharge Technology (RRT), the ‘Intelli-Start’ 1500A 12V Professional Lithium Jumpstarter (IS1500 the IS1500) recharges itself directly from a started vehicle.
It recovers 100% of its charge after staying connected for just 40 seconds.
Jump starters that can be used to start multiple vehicles have traditionally been large and heavy to move around a farmyard or workshop, but the IS1500 is more compact, lighter and easier to carry around – weighing in at just 4kg.
The Rapid Charge Technology makes use of a lithium iron phosphate (LiFePO4) battery as the power source. This enables the unit to accept charge from the vehicle alternator, at a higher current compared with other lithium or conventional lead acid batteries. The technology enables it to safely absorb a charge faster than other battery types and is also designed to allow the current to flow in both directions.
Once the unit has been fitted to the vehicle and activated, the RRT automatically engages when enough current is detected in the vehicle’s battery. Once the vehicle has been started, the unit’s battery will immediately begin drawing power directly from the alternator.
Providing 1500A peak amps and 700A clamp power, the unit is capable of starting diesel engines with up to 6-litres capacity and petrol engines up to 8-litres in size. Standard safety features include surge, over-voltage, under-voltage and over-current protection, alongside over-cranking, short-circuit, and reverse polarity (with alarm).
The system also monitors battery/switch over-temperature, battery cell balancing and a low voltage indicator.
