WFCO 9800 AD 65 amp

To be sure what you have you do need to disconnect the battery and measure the voltage across the battery and then measure what is being supplied to the battery.

I'll check the voltage after I disconnect the battery. It's 13.6 now. That's the same as the house batteries.

First problem. The new converter has a 20 amp plug. The old converter has a 15 amp plug. Other than looking for a converter with a 15 amp plug what do I need to do to power the 20 amp plug.

Odds are just change the plug or better yet change the outlet. But before you do that read the specs on the converter if it says "less than 1800 watts (I'd like it to be 1500 or less) you should be good if more you need a 20 amp circuit (more wire)
Read the spces for the LI charge voltages. they are not all that different. But I'm not sure about your battery isolator.. IF you have a B.I.R.D. type (Bi-Directional) you might want to switch to a one-way and use a battery maintainer on the coach battery when on shore power.

John, the receptacle is actually 20 amps.

Not sure what a B.I.R.D. is or where to find it. However if I end up taking the Pace to a service center, I'll have them change it to one way if possible.

The BIRD (or the similar Magnum Smart Combiner or Xantrex Echo Charger) manages charging between house and chassis batteries. It basically monitors which (if either) is currently receiving a charge and whether the other also needs charging. If it does, it closes a relay to connect the two battery banks so that both charge to an acceptable level.

Turns out I have the same or similar problem. My system does have the B.I.R.D.. How do I disconnect and /or circumvent it?

Battery Isolater Problem?

Greetings all, Am currently in the process of testing Lifepo4 batteries for boondocking and adding solar and have encountered a problem that appears to be a battery isolation problem between the house batteries and chassis battery. Testing results are as follows: Charging with installed WFCO...

It may or may not be an actual problem, but if you need/want to prevent it you can simply disconnect the RELAY wire on the BIRD and it can never close the isolator relay for charging. Just be aware that doing so also prevents the chassis battery from being charge from the house side
