Hi,
I've been researching replacing sealed lead acid batteries on my mobility scooter (somewhat modified Wispa) with LiFePo4 and the only relevant info I could find on the net was this site. I've ordered 8 off 40152S 15Ah batteries with a Battery Monitor and charger with I should just about be able to shoe-horn into the battery compartment of my scooter (to replace the two 12ah 12V batteries)
As I use my the scooter (which is very small) around my house as well as when I go out I've decided more ground clearance and squishy tyres would be good and am thinking of doing a narrower scooter version of BM3.
I can walk very short distances (although with pain), so can manage with the scooter, but because I use it so much improving the ride quality and ground clearance would make a big diffrence.
I have a spare scooter, so that when my main scooter breaks I can repair the broken one whilst using the other one as I wouldn't be able to manage around my house without a working scooter.
The main reason for changing the batteries is weight and cost, being lighter makes other peoples life easier - those who lift my scooter - either fully assembled or broken down into cars/taxis sometimes find the weight excessive (I'm now too ill to drive myself) and I should no longer need to replace the batteries every year as the LiFePo4 batteries should have a much longer life (2000 cycles should only reduce the capacity to 80%).
Best Regards
