Is it time to replace those old batteries? This excellent battery box assembly is for the Shoprider Echo (SL73) and the Shoprider Hero mobility scooters. One of the primary qualities of lightweight travel scooters is their ability to be quickly and conveniently disassembled into small, easily transportable components. The removable battery box is an essential part of this take-down system. This battery box assembly comes complete with the charger port, and a circuit breaker. This battery box comes with 24 volt, 10 Ah battery pack installed. These sealed lead acid (SLA) batteries use the Absorbed Glass Mat (AGM) design. Airline-safe, spill-proof, and maintenance free; AGM batteries are the best choice for mobility scooters and power chairs.
