CTECK D250S DC to DC Battery Charger.

[Bear60]

Mine is under the bonnet also. the only issue I have had is with the battery temp monitor, we were out at Longreach at xmas and doing some slow 4x4 so the car had little air flow and the temp was 46 deg in the shade and under the bonnet was really bloody hot therefore it didn’t want to charge my aux batt as it was saying the temp was to hot so i had to pull the monitor from out the bonnet and run it to in front the radiator where it would give a cooler reading, great safety feature and surely would save a battery but it was either that or the food go off.

still a great unit and i would definitely buy one again and recommend them also and couldnt justfy paying the price for a redarc unit.

Hi new to this would like to see some photos of where you have mounted you Ctek 250s and do you have any problems with the unit. Cheers

Hi Guys... i just got one of these units from ebay. i would love to see some pics of peoples mounting of these units..
also, do you still have to run a fuse or circuit breaker from the starting battery to the unit? and what size wire to use from battery to unit to battery?
cheers

what does this do , does it just charge the extra 5% of the battery that the alternator can't???

Any of this style unit can be regarded simply as a DC powered Battery Charger.
These devices started life to compensate for voltage drop issues in wiring when charging Caravan batteries etc.
They should be mounted as close as is reasonable to the aux battery
The D250 is not designed to go under bonnet near any heat source like exhaust or turbo or whatever (max ambient operating temp is 50 degrees C)

When powered from an Alternator or somesuch they will deliver charging current up to 20 amps max to the aux and pull maybe 25 amps (certainly under 30 in normal circumstances) themselves
When powered by solar they are limited to whatever the solar can supply IE a 100 watt panel will see a max of about 7 amps

I would use 6 B&S cable (8 will be OK but 6 is better).
I would install a 40 amp auto reset CB or a fuse at the supply (Cranker Battery post usually)
If the unit is very close to the Aux it is up to you if you want to bother with a second CB at the Aux

Apart from the solar input the don't do much at all if the Aux is under the bonnet and within a metre or two of the Cranker apart from giving you a quicker charge of a depleted aux battery

Hope that helps.

thanx Mega..
did you bolt it to the top of your fuse box?

[megatexture]

It's just resting there but its a tight fit and you can't just lift it up.

Mounted mine on the passenger side fire wall near the Aux batt

Hey Semmo
what a tidy setup.. thank you for the pic.
i was thinking of the same sort of bracket but supported from top and bottom..
did you use the existing bolt ( top one ) and a rivet?
nice location for the compressor too....

now does anyone know what is in behind this panel? is it safe to drill ( shallowly ) a couple of holes here?

[megatexture]

I thought about that area but wanted it a little further away from the turbo and catch can and I've also got my Steinbauer
Mounted on the fire wall there also
