My convertor is one that is missing the LI switch. So it will not charge the Lithium batteries fully.
Now when I bought the batteries, the manual said to fully charge them first before installing.
So I bought a 20 amp LI battery charger.
Well the converter is basically just a battery charger.
So I ran it a bit using the convertor. Then I figured what the heck, why not just us the LI charger. So I did.
Now me being the kind of guy that I am, I was sooo tempted to show an installation where the charger was plugged into the inverter and the charger output was hooked up to the inverter input. think on that for a bit.
But I am refraining from that. What I did do was plug the charger in the 110 outlet in the basement that is there for a TV and the output is on the Inverter input. I did that because I was being lazy and just wanted to see how things worked. The inverter input is basically the same as hooking up to the battery.
I have a victron smart shunt so I can monitor the batteries.
I used the charger for about 6 weeks of my 3 month grandkid tour.
The charger worked fine and the fan on the converter never came on.
Yes, the charger had to work a bit harder than the converter would. Because of the current output differences
yes the LI batteries were fully charged
and this will work if the LI batteries have a BMS, which mine do.
Thought I would share.
