Clean Republic, one of the largest retailers of electric bike conversion kits in the US and owner of the Hill Topper and ProPack brands, selected AllCell Technologies to supply US made lithium-ion batteries. AllCell’s batteries are protected by the company’s proprietary thermal management system (earlier post), which limits maximum battery temperature and protects against overheating, leading to an improvement in cycle life.
The new battery was jointly developed by Clean Republic and AllCell, and provides riders with a 40-mile drive range, a significant increase from Clean Republic’s existing 10-mile and 20-mile battery options.
The key to the improved battery size, weight (6 pounds /2.7 kg), and performance is AllCell’s patented phase change material (PCM) thermal management system. The PCM surrounds each lithium-ion cell in the battery pack, where it absorbs and conducts heat away from the cells as they heat up. This simple and effective technology requires no energy to operate and can double the cycle life of the battery pack, according to AllCell.
