dual NIMH batteries extend range in small mobility scooter

dual battery 16AH scooter battery
|
The stock lead acid batteries used on mobility scooters are 12AH
the mercedes 12V NIMH are only 8.3AH
I decided to put in a DPDT switch and have two 24V NIMH packs in my scooter pack.
Bank A and Bank B
Charge bank A , flip to bank B and charge again to fill them both.
this will give a total of 16AH.and provide plenty of range.
A friend also had a mobility scooter which had dead 12Vlead acid gel cells and we built him a dual NIMH pack as well.
We both had a chance to try the scooters out and found that a long day outing hardly drained one of the two packs.
Since these NIMH batteries were designed to last the life of the hybrid mercedes they were pulled from, they should give years of reliable service with the light load that the scooter will require
