Ablemail B2B Charger Unit. Model 12-12-30

[Dream Chaser]

Hi all. As part of my on going 'day van' conversion I am looking for feedback from anybody who may have fitted the Ablemail 12-12-30 battery to battery charger unit. Looks a fairly robust unit with a simplistic approach for the install. However I was looking to install in the engine bay & run a fused 10mm csa supply through to the leisure battery in the rear cabin. (No space under the swivel captains seats).
Advice, & comments gratefully received. Cheers

I installed one of these under the drivers seat, alongside the leisure battery. It seems to just work.
I bought mine from travelvolts, along with the wiring required. I think they advise that you install it as close to the leisure battery as possible.

Same as @Pete C above, put mine under the drivers seat with battery. Easy to wire up with instructions from Travel volts where I purchased. It just works!

All DC-DC chargers should be mounted as close to the target battery as possible. The Ablemail is a great unit, very robust, extremely effective and excellent value.

Fitted one under drivers seat along with leisure battery will try to upload a picture

Yip. Can concur with everything said above. Mines been very good with both battery to battery and the solar inputs. And at @travelvolts is your man for the full kit.

So what is the technical reason for the charger to be near the battery to be charged? I can see that it would be best to have the charger in a defined temperature environment i.e. in the "people area". But the cabling to the charger will be carrying almost exactly the same current as the cabling from the charger. Minimizing the total length of cabling makes sense. Do you get emc emissions from the output cables of these chargers?

I have this unit fitted and opted for the battery under the drivers seat and charger under passenger. Other half is an instrument technician and had concerns about everything being so close together and heat build up so we opted to split them. Also means got plenty space to access the additional fuse box for the various lights and extra sockets that are powered by the leisure set up.

As above fitted under passenger swivel seat next to battery. Had previously used the Ring unit with loads of issues. The Ablemail just works. Not had to touch it since install.

Hi just ordered from ablemail amt 12-12 trickle charger (not arrived yet) to keep vehicle battery sweet if solar panel fitted
Hoping to put that under drivers seat with everything else

DC-DC chargers will output what the battery needs largely irrespective of the incoming voltage (within parameters) so volt drop on the supply line isn't that critical. To keep losses to an absolute minimum on the output side it is advisable to have the charger as close as possible to the target battery. There may also be temp monitoring built in to the charger depending which model you fit.
There will be EMC emissions on any DC circuit unless it is screened.

Thanks. Should have thought longer before asking the question. I can see if the output does not have extra "sense" wires the voltage drop on long cables will mean the charge termination voltage will be sensed incorrectly and the battery never fully charged.
