Battle Born Charging
This might answer some recent questions. The table is not accurate wrt to the BB comments--don't go by it by the table itself. Wade through the questions and answers to get the true picture. Tak...

"It looks to me that when you reach 45 amps is a good time to stop charging"
BB says you need to get the battery above 14v to get the BMS working. I don't know if you need to balance every time.
Your 60 amper was not at 60 at first. This could be from its wires not being fat enough or from the battery not accepting 60 amps at that SOC. Could even be a loose connection--can do a feel for that if one is hot. Amps tapered from the first, no constant amps. Looks like Absorption all the way.
60 amps on a 100AH battery is .6C not under .5C as I understand it.
Yes, good time to reset the monitor. The temperature did climb while being charged, so some of your amps went to heat, not SOC, same as with all batteries.
So there is a charging efficiency percentage to apply. That monitor may have a default one like Trimetric's that you can adjust for Li-ion.
You said earlier you were concerned about charging in the heat and the blurbs warn about that too. Your temp rise shows why. The Li specs somewhere mentioned a "Thermal Runaway" number, forget where. So that is like an AGM too.
I lied about not posting to this thread anymore. Glad to see LY's comment.
