Product Details
The GEB 161231 3.7V 53Ah High-Capacity Lithium Polymer Pouch Cell is an industrial Grade-A high-energy lithium cell engineered specifically for commercial & industrial energy storage systems (ESS), solar battery banks, and electric vehicle (EV) battery modules. Built with an advanced multi-tab laminated pouch architecture, this cell delivers a verified 3.7V nominal working voltage and 53Ah rated capacity (196.1Wh single-cell energy). Measuring 16.0 ± 0.5 mm × 120.0 ± 1.0 mm × 310.0 ± 2.0 mm with a calibrated net weight of 1.08kg ± 0.03kg and ultra-low AC internal resistance ≤ 0.8 mΩ, it easily sustains 53A (1.0C) continuous and 159A (3.0C) pulse loads with superior thermal dissipation and extended cyclic stability.
Product Overview
The GEB 161231 3.7V 53Ah High-Capacity Lithium Polymer Pouch Cell for EV & ESS delivers exceptional volumetric and gravimetric energy density for large-scale energy integration. Utilizing an optimized NCM cathode chemistry, high-conductivity electrolyte, and wide ultrasonic-welded nickel/aluminum terminals, this 53Ah pouch cell achieves an ultra-low internal resistance of ≤ 0.8mΩ, substantially reducing I²R resistive heat generation during heavy continuous charging and discharging cycles. With exact physical dimensions of 16 × 120 × 310 mm and high cycle endurance (≥ 1,500–2,000 cycles), it is widely deployed in commercial solar ESS containers, server-rack energy modules, light electric vehicles (golf carts, sightseeing shuttles), and heavy autonomous mobile robots (AMRs).
