Quantum Blast 850 Parts

This page lists replacement parts and accessories for the Quantum Blast 850 power chair. We carry 24 volt AGM battery packs and battery cables, Remote Plus and Microdrive joystick controllers, motor brushes, circuit breakers, anti-tip wheels, bearings, Tru-Balance 3 armrests and armpads, footrests, Stealth and Tru-Comfort seat cushions, and add-ons like cup holders, mirrors and saddle bags.

For batteries, the store lists the 22NF (55 Ah) 24 volt pack with post or screw terminals and the Group 24 (75 Ah) 24 volt pack, so check which size your battery tray holds. The motor brush (DRVBRSH1012) is listed for the Blast 850. Many armrest, seating and joystick parts are shared across Quantum chairs with Tru-Balance 3 seating. Your model number is on the label on the frame, usually under the seat. As an authorized Pride Mobility dealer, we supply genuine OEM Quantum parts, with compatible alternatives on select items.
