Battery help - Auxiliary, leisure and powerstation

[Vanwithnoname]

I have a 2018 T6 Startline that is about to be converted. I will be adding a leisure battery for diesel heating, lighting etc. I am looking at the Roamer 230SEATBASE4 or similar. I would also like to add a powerstation (Ecoflow Delta 3) that can be removed from the van if requried, but that will charge when the vehicle is being driven. The van already has an auxiliary battery under the passenger seat (photo attached). This would result in 4 batteries being charged when the vehicle is being driven. Would this be possible? If so, what is needed to make it happen? Ecoflow have their Alternator Chargers. I have also seen various references to DC-DC Chargers, but I have to admit that I don't really have a clue.

I won't be doing the work myself (which is obviously a good thing as I don't know what I am doing), but I need to know what it possible before I start buying stuff and/or asking the for it to be done.

Any help would be appreciated. @Dellmassive ?

ok,

so you need to swap the OEM battery for the ROAMER - good move

ROAMER Discount code - T6FORUM Roamer - Premium LiFePO4 lithium Leisure Batteries


see here for lithium batterys - Lithium LifePo4 12v Batteries - Time For An Upgrade?

...

you need to swap out the split charge relay here for a DC-DC charger.

that will enable you to charge the lithium battery properly. . .

see here for DC-DC chargers - [Guide] DC-DC Charger (for leisure battery) -- How I Done It --

then add a ATC or MIDI fuse box for your leisure electrics and you are good to go.

thats the basics for the leisure setup.

then you can look at adding theECOFLOW.


you can add in a SLOW CHARGE, by connecting the EF to the 12v battery like this. . .

As @Dellmassive says if you have the 3 pin XT60i cable the 8A limiter is removed: There is a small typo there, he meant higher current not higher voltage. Yeh, it's both. It sets the solar mode which will allow the 60v 15A, but it's graduated to stop the socket from melting. So as the PV...

basically a 8A max connection to the LB (leisure battery)





...



or - if you want a FAST CHARGE - then you need to use the EF ALT CHARGER.

this can be connected to the starter battery or the LB, - as you can set the charge rate in the APP.


I've had it running from the leisre battery and it worked fine.

[Dellmassive]

get that installed. . .


then if you find that you need the EF charged faster, , , look at adding either a 1-2Kw Mains inverter, (that battery will run upto 3kw inverter)

and charge your EF from that mains. . .

or


get the EF ALT charger fitted. either to the SB or LB.
