Renogy vs. LiTime

[Grandesigner]

So I just replaced my 2 AGMs with a new LiTime 230 Ah battery with the intent of taking advantage of the user mode vs. the built in Li mode on my Renogy Rover 40A controller. Problem is that they use different terms for charging and discharging modes, so I can't really correlate them well enough to take advantage of the User mode vs. Li mode, which would fine tune the management of it all. The differences are small but I would really like to comply with LiTime's specs.

Anyone else run into this issue?

Could you be a bit more specific? What are the terms you're trying to resolve?

the litime has a built in bms......I just set my charge controller to a lithium mode and the max charge voltage of 14.6. then I let the batterys bms manage the battery. These batterys have a built in intelligence and will just about take care of themselves.

The only hitch in making this a blanket statement is Cold weather charging cut off.......Some batterys have it and others don't.

You bet, thanks for the lead in...
Here is the LiTime spec


And here are the Renogy specs

Ignore my hand notes and look at the last 2 columns...

This one has the low temp protection.

select user profile and plug in the numbers from the litime spec sheet

It looks like you'd be fine just using the LI profile on the Renogy C/C.

Yup, that's what I tried, but after a few entries it did not make sense at all. Let me know what you come up with...

Okay, we got one vote for 'close enough', do we have a second?

Yep, add me to the “close enough” camp. IMO unless you’re running the battery down to nearly zero capacity the charge controller will handle the charge duties just fine. And the battery’s BMS will keep you from doing any real damage.

Another member here has good advice for people like me with a bit of OCD: “Just go and enjoy your trailer in the great outdoors.” Great advice

Sold...that was my first idea anyway. Just wanted to get some feedback from others here.
I doubt I will will run it down that much, not even full discharging cycles is my hope and guess.
