Anyone upgrade to Lithium LiFePO4 Battery?

[lcwarnke]

I have a 2007 Octane ZX T19W and my batteries are dead, so thinking of upgrading to Lithium LiFePO4 Batteries. Has anyone done similar? My trailer has a built in generator and I’ve switched everything to LED. Just wondering if the batteries are worth it given the charger unit will also need to be upgraded in the trailer.
Thanks.

I don't have an octane, but many have in all RV's, including me. So far they have been great. Zero maintenance. Lightweight. Lots of available AH. Can charge quickly at high amp rates. Supposedly long lifespan, may be cheaper in the long run... we will see! My main dislike is most cannot be charged without damage below freezing. I installed a heater for them, so far no problems. My charger is not lithium compatible in that it will never fully charge them, but I rarely turn it on and let the solar charge them. Snow has been on my panels and I may have to switch it on in a few days, that will charge them to around 80%.
Shop carefully for LiFePO4 Batteries. Some do not have temperature (cold weather) shut off. Some may be rated 100AH, but only have a 50A charge - discharge capability. Also, Bluetooh monitoring it a nice thing to have.

X2, Plenty to read. This programmable search engine for the JOF is handy also-

I entered lithium batteries and I got 988 results on this forum alone...

There is a YouTuber named Will Prouse that explains lithium batteries in easy to understand terms. I call FLA technology the batteries we love to hate. FLA has its issues but when properly maintained they will provide years of trouble free service. Lithium technology has its own set of issues, operation below 32 F being only one of them. One can easily ruin coach batteries of any technology if not maintained or used correctly.

I prefer to use two 6V FLAs, primarily because it is much harder to deplete 6V of acid to the point it harms the battery. 12V acid level must be checked much more often.

Also, Costco batteries seem to fail much quicker than Duracell, and I find Batteries Plus pricing on Duracel to be within 10% of Costco. Sam's carries Duracel as well but I am not a member.

Thanks everyone. I ended up just going with a 100Wa AGM battery. All LiPo battery conversion just seemed way more than I wanted to do. I would have had to change my converter as well as installed a module so the lipo wouldn’t ruin my alternator when connected to my truck. All the extra cost didn’t make sense.
I can run solar to my AGM battery and given I have a 4000watt generator built in, I just need enough juice for DC lights and TV at night.
Again, thanks for the links and info. I spent hours upon hours and feel OK not going LIPo for now.
