Lead is the worst choice by far, it suffers from the "peuKert effect" (sp) which sucks power from the motor when you need it the most, like accelerating from a stop light. And only has about 300 cycles.
Pay more at the beginning and have better power density, half the weight with NIMH, li-mg or LIFEPO4
There is a group buy on
www.endlesssphere.com for top quality LIFEBATT's going on right now, but will be over end of the month.
