My First Whitepaper - Free Sneak Highlights!

My first white paper discusses in some detail - Lead Acid versus LiFePO4.

Here is a quick summary of the high points:

• EnerSys 12V, 17.2AH Sealed Lead Acid Battery at the 1 hour rate deliver just under 60% of their rated power, at 10.3 Ah that means - 0.6C load.


• 100% Depth of Discharge will shorten the life of the battery to just 250 cycles. That is 1/6th of the life of a smaller 30% Discharge, of 1,200 Cycles.


• (.3 [30% Discharge] X .6 [.6C Load of 10.3 Amps] = .18 X the Available 1 hour Energy [18% times the 10.3 Ah = 1.854 ah per Cycle] to get to the 1200 cycles!)


• ThunderSky 40Ah Cell = 1/4 the weight, Enersys costs more than 2.1 times the price.


• ThunderSky Cell can do 1000 Cycles at 100% discharge, and at 80% Discharge do 3000 Cycles, and at this point, = 64 Enersys Batteries for total energy delivery.

Bottom Line - it covers some excelent general comparisons.

I found some good data on the 20Ah SLA versus a 20 Ah LiFePO4 today too!
