Description

Details

The new Painless Performance Digital Power Managers protect the main battery from being discharged under heavy or sustained loads which commonly happen when winching or running extra lighting. On startup the Digital Power Managers will direct all charging to the main battery until it reaches a full charge. It will then automatically begin charging the auxiliary battery. The DPM will sense when the load is large enough on the main battery and automatically add the auxiliary battery in parallel for added power. The included indicator light informs you of the charge state of the DPM.

This solid state dual battery controller / battery isolator eliminates manual switching or any second guessing to maintain a secondary battery in any vehicle with a 12 volt system. The DPM is capable of switching up to 280 amperes of DC current for large loads such as winches or even when jump starting another vehicle. Ideal for any vehicle equipped with high power stereo systems, high amp driving lights or winches. Included in the kit is the weather proof Digital Power Manager, 6 gauge connection cables, terminals, heat shrink, mounting hardware and a remote indicator light.

The Painless 40121 Digital Power Manager has a 250 amp solenoid included with a push button switch to be mounted in a location that is reachable when turning the ignition key to start the vehicle. This allows for jump starting by momentarily combining the two batteries while cranking the engine. The unit will not allow the electrical loads on the vehicle's main start battery to drain the auxiliary battery lower than 11.5 volts and most likely, resulting in a no start situation. When the main battery is too low to crank the engine by itself, the Digital Power Manager in combination with the Jump Start solenoid button being pushed during cranking combines the main and auxiliary batteries together to crank the engine. Once the engine is running and spinning the alternator again the Digital Power Manager will only allow charging of the auxillary battery after the main battery is fully recharged by the alternator.
