Two of my goals are high power (~4 kw) and charge control. High power gives you quicker charge times and (from what i've read) can extend the life of lead acid batteries. Charge control gives you automation and assurance that the batteries are optimally charged for both life cycle and capacity. Also, with an unforgiving chemistry like Lithiums, you must charge it correctly - any mistake can ruin a $15k pack!

Anyway, I think PWM and mosfets are the way to go, so that's where I'm headed...
