Main s hook up charge & ctek charger at same time ??

[Little owl1963]

If want charge both leisure batterys an engine battery at the same time can you connect mains hook up for leisure batterys , and ctek seperate charger for engine battery at same time .
Over winter does not get used as much .

Or is it case of one or the other at a time , of which I presume it is ??.??

On the T6.1, I gather, all batteries are charged on EHU. Leisure fully and Starter/Engine trickle charged.
So you don’t need a cTek charger.

I’ve done it! My cali’s starter battery was playing up so had a CTEK plugged into the sink 13amp mains socket while van was on hook up.

Yes.

No not into sink 3 pin plug .

I meant mains voltage in house to hook up side van for leisure battery .

Same again house mains to ctek charger under bonnet for engine battery .

Both at same time , don't think possible???

Of course it’s possible.
Connect the mains lead of the cTek to the output of the onboard RCBO then the output of the cTek to the alternator side of the split charge relay.

Translate in layman's terms rcbo ???
E.g. either hook up point ?
Rear battery charger ?
The ctek has crocodile clips , which clip to engine battery .
Explain what you mean , better , don't fully understand that way ????

The 13amp socket next to the sink is supplied via the mains hook up (which is also charging the leisure battery) so is really no different to having the ctek plugged into a socket feed from the house. It’s just like an extension lead.
The CTEK 12v output cable was put through the part open passenger window then under the bonnet to the starter battery.

Mount the cTek somewhere convenient, under the sink/under fridge/next to main charger unit.

Chop the mains plug off the cTek cable.

Feed the cTek mains cable behind the sink unit to the B pillar. Remove the trim and connect the cTek cable into the circuit breaker (the same side that feeds the mains socket)

Throw away the crocodile clip part of the cTek and use the alternative cable with the crimped ring terminals.

Locate the split charge relay (somewhere near the leisure batteries). Find the feed from the engine battery/alternator and connect the red cTek cable to it.

Connect the black cTek cable to any good earth.

Now whenever you connect the mains hookup the cTek with switch on and charge the engine battery.

Oh and add in an inline fuse for the cTek mains feed.

Good idea thanks

Shows T5 > OP relates to T6.1 which with all of the electronics I would be very careful about using duplicated charging sources.

As pointed out by @WelshGas and seemingly ignored by OP, when the leisure batteries are on hook-up (campsite or at home) the starter battery is trickle charged

This has been going on for a few days. Got me an admin delete for being pithy. Trying my best to ignore the nonsense posts and garbled requests.

Completely agree with you. I was hoping that my post would prevent others from wasting their valuable time.

Agree - we have ours on EHU from the garage for just an hour during the night. Leisure and starter battery are kept charged up. We have the dash cam on parking mode, which would flatten the starter battery in about 5-7 days otherwise. Once the leisure batteries are charged the starter battery is then float charged.
