LifePo battery and charger

[rubio171]

Looking to upgrade battery to a couple LifePo batteries and a charger that has a lithium profile to my 2019 3811MS. Any suggestions on charger that would work well for this ? Also battery you guys like.

I upgraded to lithium batteries 5 years ago. I still have the original PD4575K18LS8 FLA converter.
Works fine. Before going boondocking I use the Charge Wizard to boost it to get about 95%.
We also have Solar. I set the MPPT to fully charge the batteries when boondocking.

What amperage battery did you get?

[Daryles]

I have four 138Ah Valence batteries.
They are not for everyone. You have to make a Comm cable, download software and configure Windows 10 to talk to the batteries to run the BMS.
Newer batteries have built-in BMS and are very user friendly.

Try this pair from Amazon. Less than $800 for the pair.

We changed from 2 lead acid batteries to 3x 100 Ah Battle Born batteries. Our 2019 330RL did not have a converter with a lithium option so we bought a Progressive Dynamics converter from Battle Born when we bought the batteries. All working great with our new 12 volt compressor fridge. Battle Born is the gold standard for lithium batteries. Highly recommend. You not need to upgrade any wiring if you have 300 Ah or less of batteries according to Battle Born.

Went with a Redodo lithium battery and one of their 3000 watt inverters that also is a charger. I also bought a separate charger of theirs for just in case. Working great and you can't beat the cost. Just make sure on whatever battery you get that you charge it fully before trying to use it.
