Thread: 24 v-12 v dc/dc converters

I wouldnt be trying to run a winch off of one, ven with a good battery set, once the winch draws the batteries down the unit will see it as a dead short and thats the end of the unit.

better off getting a 24-12v charger, they're usually easy to spot amp for amp they cost twice as much as the powersupply versions.

I have used these in marine applications

SVC Maxi Series GEN II

Good quality equipment.

My 101 has dual alternators with the 12v one charging my aux 12v battery which in turn runs the ignition and aux 12v functions. I also carry a small cheap ebay 24v-12v (30amp) reducer to run the ignition and 12v functions in an emergency such as the alternator failing.

The 12v alternator is not a good fit on the engine and does hang down in the dirt a bit so requires a bit of maintenance to keep it clean and keep the belt tight.

In the next refit I am thinking about pulling the alternator out completely and have bought a OEX 24v-12v (60amp) multistage smart charger to replace the alternator. I will mount it on top of the 24v battery box and use it to charge the aux battery as it currently is - I am a bit concerned about the ability of the unit to deal with vibrations, dust and even maybe water as it is full of electronics. I will still carry my back up 24-12v converter for emergencies.

If you want to winch you need a setup like I have - 24v -12v charger charging a 12v battery and running the winch from the aux battery. As I do I would also carry a 24v-12v reducer for emergency use but these are no use in charging you aux battery but will keep the vehicle mobile.
