CTEK D250S in engine bay

[WoodySTR]

Hey just wondering if anyone has mounted the D250S in the engine bay? Pics would be great. Just looking to split the dual batteries and these seem to be better value than just an isolator

Mine is in the engine bay, driver's side inner guard. I will try to remember to get some photos for you.

That would be great thanks mate

I would not advise having it in the engine bay due to high temps, and if you do make sure the temp sensor is in a good spot


Volt 12V
Charging voltage 14.4V at 25°C, temperature compensated
Charging current 20A
Back current drain <1Ah/month
Ripple <4%
Ambient temperature -20°C to +50°C, output power is reduced automatically at high temperatures
Charger type 5-step fully automatic charging
Battery types All types of 12V lead-acid batteries (WET, MF, Ca/Ca, AGM and GEL)
Battery capacity 40–300Ah
Dimensions 192 x 110 x 65mm (L x W x H)
Insulation class IP65
Weight 0.73kg

Didn't even think about that, probably a good chance it getting that hot in the engine bay in summer.

glennm have you have any temperature related issues?

You could possibly look at mounting it in the cab on the inside of the firewall, inside the passenger's side footwell area. Shouldn't get too hot in there and then just run your battery input and output wires through the big wiring bung on that side that goes into the engine bay...

Howdy, I have 1 on the camper and another in a sealed battery box under the tray! Check but I'm sure they don't like to go swimming Red Arc are the only water proof ones "I think"- these ones are just "water resistant" ! Check but I'm sure I read it some where "after I purchased them both" dohh.. Got 2 for $500 from memory ..
I have a redarc duel bat set up under the hood so when the start battery is up to charge it throws over to the ctek in the battery box that charges a 120ah AGM at the correct charge rate. The beauty is I can wire up a socket for the solar connection to the ctek on the side of the tray.. cool huh cheers Vic

I found behind the seat to be the best spot as I did in this old thread.

Remember that charger needs to be as close to the aux battery as possible to work to maximum efficiency. You can run an Anderson plug through the air vent behind the seatbelt to plug in a portable solar panel too.

Thanks for all the input everyone. John I actually thought the CTEK was meant to be mounted as close as possible to the charging source not the AUX battery.
I might just end up going with a basic isolator

Isolator!-it depends on what type your second battery is? if it's AGM or alike the charge coming from the car alternator is not enough to "correctly" charge these type of batteries.. just say'n....

What more info do you need Jim?.

 

[vicszd30]

I found out the hard way- charging off the 12v alternator shortens the battery life .. Rattle 'ol Tony's box -he loves he's electronics and will fill you in on all you need to know.. I'm like you- learning as I go, expensive but educational cheers vic

 

[vicszd30]

Oh and I think it's -closer to the Aux battery is best... All the paper work for them is in storage and packed away now-sorry fella but I think that's right...

 

[happy john]

Yeah Jim lets move on and fix our Nav faults and help to fix

huh??? who's Jim? but more importantly what tf are you trying to say here?

I'm confused now. Someone had a few drinks tonight?

Isolators don't really matter where they are mounted because they give the same voltage on both sides of it. The dc-dc chargers though, closest to the battery being charged the better. Because they boost voltage, if you have it mounted in the tub then as long as it is getting voltage above its minimum input voltage it will boost it back up to charge the battery. If you're using it in the engine bay the same rule applies, it is just the heat factor obviously...

 

[happy john]

I believe the more the temp the charger backs off the voltage to protect the battery.

Wish I could mate, most day's and nights I am taking the kids to something.
