Product Details
The GEB 11.1V 200Ah (2.22kWh) Cylindrical Lithium-ion Battery Pack is an industrial high-capacity motive and energy storage power system engineered with a 3S cylindrical cell architecture. Delivering a verified 11.1V nominal operating voltage and 200Ah rated capacity (2,220Wh / 2.22kWh total energy), this pack is equipped with a heavy-duty 100A continuous (150A peak pulse) smart BMS featuring multi-tier hardware protections (OVP, UVP, OCP, SCP, OTP). Assembled with laser-welded pure nickel busbars, high-temperature structural cell brackets, and internal epoxy insulating baffles, it weighs Approx. 16.8 kg and delivers rock-solid DC power for mobile robotics, marine low-voltage DC grids, and critical field workstations.
Product Overview
The GEB 11.1V 200Ah (2.22kWh) Lithium-ion Battery Pack solves high-drain continuous energy requirements where standard lead-acid batteries present prohibitive weight and space penalties. Providing 2.22kWh usable energy at roughly one-third the weight of equivalent AGM/Gel systems, it integrates Grade-A high-capacity cylindrical cells grouped under strict barcode impedance sorting. Measuring 330 × 220 × 160 mm and protected by a flame-retardant heavy-gauge casing with dual M8 brass post terminals and Anderson SB120 connectors, this power plant easily handles continuous 1100W loads. The internal active BMS balances series strings automatically during top-of-charge CC/CV regulation.

Integration & Operational Boundary Conditions
Charger Specification: Always connect a dedicated 12.6V CC/CV lithium-ion charger. Do not use legacy lead-acid chargers featuring desulfation pulses or float voltages exceeding 12.6V, as this will trigger the BMS over-voltage latch.
Mounting & Vibration Isolation: When installing on mobile automated platforms or marine craft, secure the battery pack within a rigid battery tray using shock-absorbent neoprene pads. Do not puncture or apply direct clamping pressure on the outer shrink wrap.
Series / Parallel Stacking Constraints: This pack is designed for stand-alone 12V DC service or parallel capacity expansion (up to 2 units in parallel of identical batch and voltage). Connecting packs in series for 24V/36V systems requires factory-customized high-voltage BMS configurations.
Equipment Compatibility & Engineering Fit Check
Before deploying GEB 11.1V 200Ah (2.22kWh) Cylindrical Lithium-ion Battery Pack with 100A-150A BMS, verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 11.1V / 200Ah power curves.
- Commercial designs requiring high volumetric energy density and predictable discharge curves.
- Projects requiring batch consistency with automated barcode impedance sorting.
⚠ Operational Constraints & Limits:
- Do not discharge below minimum cutoff voltage or charge beyond 12.6V.
- Maintain operational surface temperature within -20°C to +60°C discharge (0°C to +45°C charge).
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
