5V 10A 256CHS High-Precision LiFePO4 Battery Capacity Tester for Prismatic Cell Testing
Product Description
ACEY-BCT520-256H prismatic lithium cell grading machine is specifically developed for lithium iron phosphate (LFP) prismatic cell testing, providing accurate charge-discharge analysis, capacity grading, and cycle life evaluation. Each testing channel operates independently to ensure consistent measurement accuracy while preventing channel interference.
Designed for battery manufacturers, EV battery production, energy storage system (ESS) suppliers, and research laboratories, the tester supports flexible testing profiles, real-time monitoring, and automated data recording. Its high-precision measurement system enables reliable quality inspection throughout battery manufacturing and incoming cell verification.
