Hi all,
Will this work?
The picture above is self explanatory.
400 watt solar panel
Redodo 12V 100Ah
Ecoflow River 2 Max
Should I fully charged the two batteries first before connecting them in parallel with victron?
Thanks
Im not sure this config is the proper one. DC socket at River Max is a SOLAR connection a socket, not a battery (as far as I can see it in the manual)
From the solar panel to Victron , the connector is MC4 to XT60i and an xt60i male pigtail
From Victron charge controller to Redodo, the connector is pigtail O-Ring
From the Redodo battery to the Ecoflow River 2 Max, I will be using an XT60i O-ring connector
You need a orion dc to dc charger in between the battery and the ecoflow, the mppt charger can not charge two different type batterys at the same time
Both are LiFePO4 but of different Ah
If the charging specs are the same and they both have their own bms, it could work without, but my advise is to use one
Definitely fuse it.
I assume that the ecoflow is being connected from the battery into the car charger port?
If you are trying to use the solar input that is not likely to go well.
In the diagram, ecoflow is connected via xt60i connector from the battery into the solar input port
For some reason i did not see the i on the xt60 i.
But still i would also fuse it.
Actually the ecoflow river 2 max portable battery charger can take solar input up to 220 watt/50v.
Will see, thanks
More concerned about safety. (An over current from the battery.) If mistakes are made or a cable is damaged or shorted, there needs to be current limiting. Was never worried about the voltage on the input of the ecoflow from the battery.
Ahh in that case we can always limit the amp in the victron mppt charger.

Max charge current
This setting sets the maximum battery charge current. It is by default set to the maximum solar charge current.
Use this setting to reduce the charge current, for example, when a smaller battery bank is used that requires a lower charge
current.
The battery is the unlimited current source - not the MPPT. Fuse by the battery to the ecoflow.
The ecoflow can regulate it’s own charge.
The Orion dc to dc charger is too much for me.
By the way by saying fuse it, does it means using a fuse in between? What fuse should I use?
Alternatively can this be used between the battery and ecoflow?
It can limit the voltage and current and only cost about $25 bucks?

The xT60i makes the dc to dc sort of redundant.
The fuse rating at least 1.25 times the input current or tracking amps of the ecoflow model you have. (Rounded to the nearest fuse size)
Check the menaul for the mppt as well there is a fuse recommendation there as well.
