Re-Lion 300 AH Lithium Battery

Has anyone started using this type of battery and if
so, what charging profiles are you using assuming
your using classic controllers!

Have a link to the battery you are talking about ?
A lot depends on the lithium chemistry it is .

Hey Larry, I can't seem to find any info on the web
regarding this battery.  I've been told an AGM
profile will do it..but I'm curious about the temp
comp factor and how do I limit continuous float
which isn't required on the LiFePo?

You really need to find the manufacturers info for charging limits. And some of it depends on if this battery has built in BMS .
For my Calb LiFePO4 batteries I don't have a temp comp but you can't charge them below freezing ( hoping a charge cutoff temp option is added to Classic firmware some day ) .
If you look up in the forums here for Bottom Balancing you will see more details which is the way I charge mine . Can't say if it would work for the other type battery .  For my 48v system I charge up to 56v and let the Whizbang and Ending Amps end the charge at 5 amps for my 100 ah pack. Then it goes to float at 54v .  This has been working okay so far for my setup but may not be suitable for other lithium . I had to spend some time draining all the cells in my batteries first and that is why they call it bottom balancing.

Thanks for that input Larry...yes I hope the classic
will incorporate a low temp cut off in upcoming
software upgrades...I'm going to build an insulated
Battery enclosure and install a tank heater in it
to make sure the battery is always above 0 deg C

Was trying to look up those ReLion batteries  - there seems to be a lot of different claims and prices on them . One says 300 AH but shows 75 AH battery and then specs say 300 AH for 3 to 5 seconds.  One shows over $2500 , another around $1000 .
They don't mention anything about BMS .

There is a new US company making 12v LiFePO4 batteries in Reno , Nevada - I saw a video about them  from the solar place out east.

Wind Sun also sells them

I finally did the switch over to the lithium and monitored the process
over the next 3 days.. got some charging profiles from the manufacturer.
Everything seems to be humming along fine. The only area for concern
that I can see is that they don't suggest much of a charge when the battery
is at 0 deg or less, so I built a very well insulated battery box with tank
heater installed to take care of that situation if and when that situation
Arises....
I'm definitely impressed with the litiium's capability of maintaining a very
constant system voltage even under reasonable draw...and the recharge
capability is phenomenally better than flooded cells!
