Lithium Charging Question

[Bluesgunner]

I have a Roy Pow 105ah in my 2013 TXT. Everything is great!
I was reading another thread here about charging do's and don'ts.
I live in Michigan and remove my battery each fall. Re-install each spring and I'm off.
I have been running my battery low, charging it to 100% prior to storage. Is this not the proper way to handle the off season with a lithium?
Thanks
Andy

It would be better to only charge it to 80%. (all the time unless you need the range)

I always read that was more of a benefit for NMC than lifepo4... lifepo4 is rated for 2000-4000 cycles depending on the load put on the cells How many years is that for a typical golf cart? I think when you compare the price difference of a 74ah to a 105ah it doesnt actually pay off to buy a 105ah and use it as an 80ah.

I have read its best not to store lithium batteries at 100% charge though for offseason or storage without use, as it also can negatively effect life... However thats exactly how most are to be used.

Personally I discharged mine to like 70-80% for the winter storage. my other lithium setups sit at 100% all the time though as they are used for battery backup power and stored power for my campers solar setup and ive had no issues or effects that I could see... Maybe in like 15 years ill notice the effects.

I run my cart every single day rain or shine. It's the way the wife n I relax after work. Just head out down the road / woods and creep along. (country life).
I charge it to 100% and run it to 10-20%, charge it and do it again. It sits about 3 months out of the year when charging can be a problem due to outside temps.
I'm about to get it out now. Maybe next season I'll just give it a 75-80% charge in the off season.
BTW...I remove the battery and put it in the basement. A nice 60° winter rest verses a freezing environment.
