Looking to upgrade batteries
I have a 36v 12ah (12v 12ah x 3) battery pack on my ebike and am looking to upgrade them to a lifepo4 pack. What im wondering is what 36v lifepo4 pack will give me the same range I have now with my sla batteries? The simple but wrong answer is 12ah. I know you can go much farther with lifepo4 batteries and want to cut the weight down as much as possible.
(I searched but could not find how to compare the two types of batteries as it pertains to my situation.)
EDIT: Also im looking at these batteries and the 36v batteries are recommended for 500-750watts. My bike is running a quiet 180watts. Will these batteries mess it up? I assume the controller will take care of the motor as long as my voltage is the same as the SLA batteries I am using.
