It's harder to experiment with though. I'm waiting for a proven BMS lithium
solution. I only takes one bad over charge or over discharge to kill the cycle
life. If you kill a pack of AGM lead that would have done maybe 300 cycles and
died at 100 is easier to swallow than damaging your pack that was budgeted to
last 3000 cycles and gets killed at 100. It is worth making sure you have a
solid BMS if you don't have a chemistry tolerant of abuse.
My 2 cents.

I hear that "when lithium gets cheaper" banter quite a bit. I agree
that the initial outlay for lithium seems quite expensive and can be hard to
justify or even obtain. But, if you do the math over the entire lifetime of the
battery the lithium-iron at todays prices is about the same as flooded lead and
about 5 times cheaper than sealed lead. Yes, cheaper.
Yeah, I'd like to see lithium get even cheaper and it is headed that way, but
to buy lead while waiting for lithium to bottom out is just plain silly.
Have you ever mentioned to Bill Dube' that he's not going to win races with a
single gear ratio? ;-)

Unfortunately none of us are going to win races with single gear
ratio. My next project (hope) will have room for a Harley 5 speed. Our
nemisis is the range possible with SLA, when Lithium Iron or NiMH type
batteries get in a reasonable price range we can all switch and our
bikes will have renewed life (miles) ;-)
Cheers, Jeff
