Yes, that's what I've been doing. Just don't go over the max charge rate of your batteries. My 3 x 120ah batteries can handle upto 90amps charge. Next year I'll add another 30amp b2b charger (60amps total) while driving plus upto around 28amps from solar panels in perfect sun conditions, which is under the 90amp max. 🌞 bare in mind though that I'm no expert :) 😀
In the instructions it states - when a battery is installed in a vehicle and battery is ground to chassis (which is good practice) to run the negative of charger to chassis. A direct to battery connection is for charging battery in a stand alone situation.
@@SuperVanVagabondok, Yes if this is the case - then according to the installation instructions. You do not run the negative of the charger direct to battery, but instead to the chassis.
Hi I remember that one of the victron manuals said not to use them, then everyone went to use them. Remember to keep checking the cable tightness over time. M.
@@markeh1971 Didn't know that they said that. Mine seem to be working okafter over a year's use. Good advise though to check your install every now and then... :)
You're welcome. I used 10mm. Everything is all good. :) Make sure you pick the right absorbtion setting for your batteries. (Mine are 14.8v so I set the 'High' 14.7v option).
@Super Van Vagabond thanks again! I'm new on the van building! Just sourcing all electricals now after filling up my shed with insulation and sealants etc! I will have 1 agm battery with a 12v 30amp vitron dc charger. Do you think I need a 30amp vitron mains charger, or would a 15amp be good enough?
@@onemanandhisdog depends on the Ah of your leisure battery. You generally want around 10% of your battery Ah for your charger. For example; I have 3x 120Ah batteries = 360Ah in total. I'm using a 30Amp mains battery charger which is just under 10% of 360Ah (36Amps). My batteries can take 30amps each charge (90A in total) which is my max charge rate. My 400w solar brings in under 30A in best conditions, so I could add another 30A charger if I wanted (2x30A b2b or 1x 60A mains charger) It all depends on what you want to use it for. A bigger charger means a quicker recharge. Just dont over charge your battery.
@@onemanandhisdog yeah that sounds good. I went for 240Ah to start but quickly added another 120Ah when I realised how much I was using! :) good luck with your build! :)
Hi mate. I have similar set up to yours. I’m looking to understand the charger. I want to be able to connect to Mains Hook up now and again on my travels, will I be able to use this to hook up to the mains and continue to use all my 12v Devices(fridge,tv) as it’s charging my battery. Hope I make sense. Thanks
@@SuperVanVagabond Thanks mate, silly question but where do you get your cable from? after a look around the internet the price seems to vary so much so just looking for an accurate price from someone thats bought exactly what im after. nVery helpful video too by the way, thanks for sharing
Hi Matt, I used what I used as it was a 'kit' from the company I ordered it from. At some point I'm going to replace the fuse unit with a trip style fuse.
So you can add a AC solar battery charger without disconnecting the solar charger controller

Nice one brother 😇 Looking chilled & relaxed x
Thanks bro, that was a little job finished off. That should be the end of the electrics besides a few minor items to tidy up and finish. :)
Nice one bud. Looked like a half job that actually took half hour.
As we all know that doesn’t happen very often. Time for a beer. Cheers 🍻
Hi Paul, yeah it didn't take too long that install. Cheers mate :)
What its called that small white caps you put on end wire and crimped? Thanks
Ferrules is what they're called :)

Thanks for that dude! What size cable did you use from charger to batteries?

@Super Van Vagabond that's well detailed bud, thanks. Plenty to go on there👍. I'll go for 30amp as I'm opting for 2 batteries now at 120ah each

Hi there mate, yes you can use your 12v (and 240v) devices whilst charging.
@@SuperVanVagabond Thanks man. Appreciate it. I better invest in one. 😂
@@sammcmanus1138 Yeah I'd recommend getting several different methods to charge your batteries. As always, it depends how much energy you need.
Not tempted by lithium battery’s then pal ??
Yep, but I don't have the cash for them atm. Especially as I'm getting everything else in as well. Beer is costly you know :)
Hello, did you use a 6 or 8 AWG cable? 10 or 16mm
Hi there, I can't remember off the top of my head. I'll have a look later today when I finish work.
Hi there, apologies for slow reply, just had a look at it. I used 10mm wire.

@@joshlambe8259 Hey there Josh, not silly mate, it's all work until you know where :) I got mine from here:
electriccable.co.uk/cable-TECC.php
you have to calculate not copy the size
Why did you use a 40amp fuse instead of a 30amp fuse between the charger and batteries? Did you use more than a 16mm cable?
Hi Matt, I used what I used as it was a 'kit' from the company I ordered it from. At some point I'm going to replace the fuse unit with a trip style fuse.
30amp circuit on a 30 amp fuse may blow victron say
