EG4 Power Pro VS Ruixu Lithi VS Yixiang Budget Battery! Best Selling Battery Showdown!

The video tests large 48V batteries, each weighing around 300 lbs, comparing their capacity, aging, and performance under high current. UL-listed batteries are more expensive but necessary for legal permitting and insurance, and some are outdoor-rated. The testing used an 18 kW battery cycling machine to push the batteries to their limits. Capacity tests showed minimal difference between old, heavily cycled batteries and newer ones, suggesting calendar aging, not cycling, is the primary factor in battery degradation. A continuous 200-amp cycle revealed significant performance differences. The Ying batteries failed due to an overheating fuse tripping the BMS, reaching 220°F. Bypassing the fuse improved performance, but the BMS was sensitive around 200 amps. The EG4 was the clear winner, despite having the smallest capacity. Its design features a larger compartment with the BMS positioned away from cells and the breaker, preventing heat-related trips. The Rukxu's BMS design allows for easy replacement but handles heat less effectively. While cells themselves handle high current, the BMS and fuse design critically impact overall battery performance under strenuous conditions. The horizontal battery offers excellent volumetric density and build-in-place convenience but lacks UL listing. The EG4 is recommended for performance and integrated busbars, while the Rukxu is good for vertical, UL-listed applications.
