Charge converter switch to lithium in a ‘24 Delta281

[andy_anderson]

Hello all,

We installed 200ah Lithium battery bank onto our delta to help with the hog that is the 12v fridge when we dry camp. When hooked to shore power, or a generator, it seems to me (I’m no electrician) to be recharging really slowly. I’ve attach a couple shots from the LiTime Shunt that tell me no more than 13.9 amps is ever pushing into the battery. And that’s with absolutely everything turned off in the RV. Should it be charging faster? I was told the converter would automatically detect and switch settings for Li. Thanks!

A thought, have you actually checked your make and model of your converter to ensure it is of the auto detect design?
13.3 volts seems lite for a lithium charging profile.

1 or 2 LiTime batteries? Who installed these batteries and shunt? Can you show picture of entire setup....including wires?

Have you used the LiTime app to see if the batteries are limiting the incoming charge?

Most converters Alliance use since ~2023 will auto detect Lithium. However, you can also look at the converter to see if it is detecting Lithium. I think most will have an LED that highlight current settings.

2 -100 hour batteries. I haven’t used the litime app as we got the basic batteries with no BT connection. Just this inline shunt we bought. Installed our selves I think I have a picture. Found my voltmeter so tomorrow I’ll be checking power at several points

I had this thought too. I’m almost certain the converter is tucked either behind the breaker panel, or inside that cabinet below my tv. So access is gonna be… a challenge. But that is also on my list
To check tomorrow

I’m assuming that your trailer has 50 amp service? With my big lithium battery, the converter didn’t switch to a lithium profile for charging until the battery was depleted enough for the converter to know that it was a lithium battery. Try running your battery down to about 5% state of charge and then hook up to the converter to shore power.

Will try that tomorrow after I finish with a separate issue I’m fixing. Thanks!
