Can anyone please explain what the difference between LIFEPO4 and LI-MN is? Which one is best? Most current technology? Safest? I'm real close to buying the Bionx system, however, there seems to be a lot of talk about LiFePo4 type batteries which Bionx does not sell.
LiFePo4 or Li-Mn?

There is a lot of, justifiable, buzz about LiFe, but either one is probably fine once it boils down to brass tacks. LiMn is neat in that you can take a 2lb 37v3ah konion cell pack and suck 20a+ out of it easily if you're only going a couple miles and don't care if the pack only last a couple hundred cycles. To do the same with LiFe would require either expensive cells like a123 or a much bigger/heavier pack like PSI. LiFe will out last LiMn cycle-wise currently. If you want to "invest" in LiFe for the long haul you really can't go wrong, but again a cheap LiMn setup from harvested tool pack cells that may only last a year or two will provide plenty of power and by then something "better" is very likely to be available. Emoli is claiming that their next-gen LiMn cells will match LiFe in cycle-life/calendar life. I used to love emolis, but under high load riding they are not proving to last very long at all I'm finding.
Bottom line is it really boils down to what you want to spend... right now.

LiFe = 3.2v per cell ( 36v = 12 cells )
LiMn = 4.2v per cell ( 36v = 10 cells )
LiMn is lighter and more compact, i'm going on my 3rd year with the Norco's 72v 20ah pack.. still going strong.
Imo, cycle life is still dependent on how you use them..

In my opinion, Lifepo4 is great for the long range bike, that usually isn't so fast. Unless you spend real bux on a123's
If you are going to be riding a motor that draws under 25 amps average for a long distance day after day, Ping is your man. For other applications, off road hill climbing, short high speed runs, etc, other options work better, or are cheaper.
