On April 15, 2023 at approximately 0830 EST, swearengin SX-300; experimental, amateur built aircraft, departed from Leesburg International Airport (klee), Leesburg, Florida en route to umatilla municipal airport (X23), umatilla, Florida with one pilot and no passengers on board. Approximately 5 minutes after take off, the pilot noted the battery light flashing, and the battery discharge light illuminated. The pilot maneuvered the aircraft to return to klee. The pilot began emergency procedures for electrical power loss, turned off avionics and extended the landing gear. The pilot noted the landing gear pressure at 1500 PSI as the gear extended and the aircraft lost electrical power. The pilot contacted klee air traffic control, reported the electrical power loss and requested visual confirmation from ATC that the landing gear had extended. ATC gave visual confirmation that the landing gear had extended. After the aircraft touched down on runway 13, the pilot noted that the main landing gear moved when the brakes were depressed. The pilot let off the brakes and the aircraft began drifting left. The pilot attempted to straighten the trajectory, without using brakes, but was unable to do so. As the aircraft approached the 'delta' turnoff sign, the pilot braked once again to prevent the aicraft from hitting the sign. The left main landing gear slowly began to retract as the aircraft slowed down and stopped prior to damaging any airport property. The left main landing gear partially retracted and stopped. The left wingtip scraped the ground causing minor/superficial damage to the paint and primer layers on the aft portion of the fiberglass wingtip. The left main landing gear never fully retracted which prevented any damage to landing gear doors or additional damage to the wing. The aircraft was lifted and towed off of the runway/taxiway intersection. No injuries occurred and no damage to airport property was reported.
