Geeez :)  more details ...my mistake I've a bad habit of throwing all lithium under the same "Lipo" tag.   When you refer to "totally fry" are you referring to the lower cell voltage LiFePo4 has vs other lithium?

Hi ALLOY

The "fry" terminology is mine.  What the reference source I read used was more like "irreversibly damage".  I've tried to see if I could find that reference, because it gave a nice paragraph of information about the differences with regard to overcharging, but alas, I can't.  What I did find was additional references however to the charging characteristics of various lithium batteries and I've included it as a .jpg attached.   I have not been concerned about voltage cell charging states because the LiFePo I'll use have built in BMS to prevent overcharging (with Bluetooth to monitor what's going on in each batt pack), and then on top of that I"ll have a charger set to the appropriate parameters.  I'm not building my own using individual cells, so getting into "charging voltages" is more detail than I've had to mess with.

Here is a link to info and voltages for various lithium battery chemistries:  http://batteryuniversity.com/learn/article/types_of_lithium_ion

LFP, which is what we use in RV's has a nominal cell voltage of about 3.2V

The others are in the 3.6V to 3.7V per cell,  Way to high for the LFP.
