Routing the Cable to install a EcoFlow 800w Alternator Charger

It does allow for reverse charging, I did it although to the aux battery at the back.

Hello and thank you for the reply.





In fact, I would like to be able to do reverse charging on the engine battery in case it is completely discharged because I often travel to fairly remote and isolated areas. In that case, I have no other choice than to connect it to the engine battery?

As It's quite a hassle to pull the cables to the engine bay I would hook it up to the aux battery first and check as it's very easy to do if you don't have to mount it permanently just for the test.

Dans ce cas, comment puis-je savoir si le courant est envoyé à la batterie du moteur et non à la batterie auxiliaire ?

Hmm, yes that's a good question, I suppose you need to attach a volt meter to the starter battery and observe the voltage rise.

Thanks you i will

Hello, I would like to connect my Ecoflow alternator charger to the engine compartment battery because I don’t think connecting it to the auxiliary battery under the seat would allow reverse charging. Could you tell me where you routed the cable from the engine compartment?

There is already a connection to the starter battery in the engine bay connected to the charging relay under the front seat (passenger side on UK vehicles). So you could easily tap off that connection. But be aware of load on the cable. I would probably avoid charging at full 800w if using that option.

Reverse charging starter battery when connecting to the leisure batteries won’t work. The relay only activates when the engine is running.. which is not possible if the starter battery is flat lol
