For BFL13 et al... FLA vs AGM vs Li vs heated Li
I have no dog in this discussion. Just passing the info: https://www.youtube.com/watch?v=iy3hga_P5YY Interesting!

Hi Steve,
On the same search I found this:

"Through experimental analysis of batteries, we draw the conclusion that LiFePO4 battery has a long cycle life, good safety attributes, a high theoretical capacity, low environmental impact and other characteristics; however, it also has many shortcomings, such as need to prevent over-charge, over-discharge, and over-temperature. Otherwise, utilizable capacity of the battery will decrease rapidly, and cycle life will reduce quickly."
Translation: LiFePo4 are unforgiving of any abuse and may bite you in the behind.
One needs a magnificent battery management system. It is not in my skill set to design such a beast.
who needs to build a BMS. you pay 140 cdn and you have a very good one. if you can wire a battery bank togeather you can build a LFP battery. all your doing is conecting four 3.2V cells togeather with bussbars and you hook the 6 or 7 wires from the BMS to thoes cells.
