Got the walker built. It was good to get the old tanks filled and do some tube brazing once again. It's got me thinking again.
Will post some photos once we have the accessories tidied up and the customer gives approval.
Used a self balancing scooter motor and conventional thumb throttle and ran the 36v motor on a 24v controller and 8s hobby 4.2 lifepo4 battery pack. Speed and movement just about perfect. Customer wants to simplify the charging so a BMS battery - system needs to be sourced for future builds. Anyone have some ideas what may be best for the average older not tech savy consumer.
