The Misen E889 3.7V 88.9Ah lithium-ion pouch cell is designed for electric buses, electric trucks, mining vehicles, industrial battery systems and energy storage applications. Its slim aluminum-laminate structure, high volumetric energy density and short-duration high-current capability support compact, high-energy battery module integration.
01 3.7V 88.9Ah High-Capacity Cell
The rechargeable E889 pouch cell provides a nominal voltage of 3.7V and a rated capacity of 88.9Ah. Its large single-cell capacity is suitable for customized traction batteries, industrial power systems and high-energy battery modules.
02 331.6Wh Single-Cell Energy
Each cell provides 331.6Wh of nominal energy and a volumetric energy density of 656Wh/L. This high energy density helps pack designers achieve greater usable energy in a slim enclosure while reducing unnecessary module volume.
03 Up to 550A Pulse Discharge
Maximum discharge current reaches 550A for 10 seconds, while maximum charge current reaches 350A for 5 seconds at 50% SOC and 25°C. These are short-duration ratings for acceleration, load peaks and other high-power operating conditions.
04 1.4mΩ Low Internal Resistance
Internal resistance is specified at 1.4mΩ under the stated SOC and temperature conditions. Low resistance helps limit voltage drop, heat generation and energy loss during high-current operation when paired with suitable tab connections, busbars and cooling.
05 30-Minute Fast-Charge Window
Under the specified test conditions, the E889 supports charging from 11.4% to 77.2% SOC in approximately 30 minutes at 35°C. Actual pack-level charging performance depends on the charger, BMS, cell temperature and thermal-management system.
06 Slim Large-Format Pouch Design
The cell measures approximately 452 × 113 × 9.9mm and weighs 1150.6 ± 18g. Its aluminum-laminate pouch body and flat tabs at opposite ends require suitable insulation, tab support, mechanical restraint and protection from bending or puncture.
Custom battery module applications: The Misen E889 pouch cell can be integrated into electric bus batteries, electric truck batteries, mining and construction vehicle batteries, industrial power systems and energy storage modules. A complete battery pack requires a compatible BMS, fuse, contactor, busbars, insulation, temperature sensing, thermal management and secure mechanical support. Continuous-current limits and final pack performance should be verified through sample testing under the intended operating conditions.
