Short answer. YES. Bonus, just 23# each vs. SLA @ 65#, double the useable capacity, and can be installed almost ANYWHERE.
You can get a battery with Bluetooth monitoring so it’s even easier to track usage.
I replaced my battery and bought a $20 plug in charger to top off and equalize my battery occasionally. Not paying for a converter charger upgrade, parts alone were about $270.
The stock converter charger, even if non Lithium capable, will charge the battery to about 90% on the average. So far, mine seems to be keeping them (bought two batteries) at 100%.
You can also use solar to top them off if you get into that.
The ONLY downside to consider is LiFePO4 batteries can be damaged if charging is attempted below freezing. So if you want to leave it mounted year round in cold climates, you’ll need one with low temperature protection in its Battery Management System (BMS), or take other actions. My 2nd battery’s manual (yes, it has one) states to not store it under 14*F. My 2nd battery was bought cheaply and doesn’t have all the same BMS as my 1st one.
