Laptop batteries are a suggestion, the answers are many. The original design employs lead acid batteries and does its job well. The OP is considering upgrading the battery bank along with the motor rebuild. I am suggesting lithium cell chemistry as a viable option.

Due the wide usage of the 18650 cells in all kinds of consumer electronic equipment, and now adopted by Tesla, the cells and their support equipment are widely available. They can be found new or used, in small or large quantities, with relative ease. The charge control / battery management system (BMS) modules are also not uncommon, and can be found in a wide range of available configurations. For a little bit of tinkering and testing, a reliable, rechargeable, custom power source could be assembled.

All it costs is time and money.
