I have one of these Raps12r units in the back of the Patrol with my Waeco cf40 running off it. The fridge is set to low in regards to power cutoff. The Raps unit has its own cutoff, which seems to be around 12.4v.
Anybody know if this cutout can be adjusted or disconected? It is being powered by my second battery, not the start battery, so the cutout is not all that important in keeping enough power to start the car.

Thanks in advance

I have to ask, why are you using the Raps unit in the car? Why not just plug the fridge staight into 12v supply?

The unit was originally connected to my main battery before I got my second battery. I kept it all connected( except battery change) as it gave me the choice of having the power with engine or without, as well as the choice between hella plug and standard, which ohten both get used.

PS. I'm not talking about the raps battery pack.

RAPS is heavier wiring than the standard car wiring, that is the reason I bought one.

Fair enough. You'd have to rewire to remove it. Still, if you're worried about voltage drop....

not sure why you would need to rewire it or remove it anyway. raps has heavier cable which you can connect to either battery by just relocating where you terminate it under the bonnet. also has many features in the unit itself as mentioned. its basically what most people do when running larger cable except for the bonus features on the raps unit. engel make something similar for theirs too.

i think my waeco is the same model as yours and i also have the raps setup. if waeco is set to high it should cut off at 12.5V and at low should be 11.4V - from memory. you do have to have enough voltage being put back into the batteries from the car when its running. have you checked what it is, not just as soon as its started, but also after it has warmed up? i am having issues with my petrol 120 prado not putting out enough volts after its warmed up. starts out at 14.04V then drops rapidly after it warms up (and drops even more if i have spotties or fogs on also) so i need to check my alternator etc is working correctly. i know some people fit a diode to their diesels to increase the amount of voltage their car produces but not sure about it being an issue on petrol prados like mine, and i dont know about patrols either whether there is any issue there for your model.

i think there is a patrol forum where it may be worth asking the same question. it may also be worth reconnecting the raps cable to main battery and checking what happens to the waeco on it and see if you have same results as when its connected to the aux battery. i will be interested in what you find out with yours and will post up what happens with mine when i get time to check it out further, cheers....

My apologies. Was thinking of a different setup... Should check model numbers before putting fingers to keyboard. :'(

Hi SDG,

I have the RAPS12 in my car and the paperwork that came with it has the following information. If you set it to on/off with engine then you will achieve what you want.

ON/OFF with ENGINE (GREEN LED)
On >13.4 volts
Off 11.4 volts - Approx 40% Battery remeining
Off < 10.8 volts - Approx 5% Battery remaining

Regards,

Sn00py2

And again


On/Off with engine - On at 13.4 volts, Off at 12.8 volts.
On/Off with volts - On at 11.4 volts, Off at 10.8 volts.

Hope this makes sence.
