Product Details

Direct Answer / Engineering Summary

The GEB 7.2V 3000mAh Sub-C Ni-MH Rechargeable Battery Pack (6S High-Drain) is a ruggedized Nickel-Metal Hydride (Ni-MH) power assembly built from 6 Grade-A Sub-C cylindrical cells configured in series (6S1P). Delivering a verified 7.2V nominal operating voltage and 3,000mAh rated capacity (21.6Wh energy), this pack sustains 10C continuous discharge currents (30A) and 15C pulse bursts (45A ≤ 5s). Designed with heavy-duty pure nickel interconnects, thermal-grade shrink tubing, and standard Tamiya or XT60 terminals, it is optimized for high-torque RC vehicles, cordless tools, and robotic actuators. System charging requires standard Ni-MH negative delta voltage (-ΔV) termination (typically 5–10mV per cell) or 0.1C constant-current timed regimes.

Engineering Overview

Product Overview

The GEB 7.2V 3000mAh Sub-C Ni-MH Rechargeable Battery Pack is engineered for high-drain commercial and hobby applications requiring stable electrochemical discharge under dynamic mechanical vibrations. Featuring six matched 1.2V 3000mAh Sub-C cells laser-welded with low-resistance nickel busbars, the pack provides robust power delivery without the severe thermal sensitivity or volatile flammability risks associated with high-stress lithium chemistries. Measuring 134 × 47 × 24 mm and weighing approximately 380g, it drops directly into standard 7.2V RC chassis, commercial utility lights, and cordless industrial equipment. Integrated multi-strand 14AWG silicone lead wires minimize IR drop during maximum acceleration pulses.

Engineering & Integration

Integration & Operational Boundary Conditions

Charger Detection Requirements: Fast charging must utilize dedicated Ni-MH algorithms featuring negative delta voltage (-ΔV) cutoff set to 5–10mV per cell (30–60mV total pack) or temperature increase slope (dT/dt) sensors. Never use constant-voltage CC/CV chargers designed for lithium batteries.

Deep Discharge Prevention: Do not allow pack voltage under continuous load to fall below 6.00V (1.00V/cell). Excessive deep discharge below 0.8V/cell causes polarity reversal in lower-capacity cells and leads to permanent capacity degradation.

Storage & Maintenance: For long-term storage exceeding 60 days, store in a cool, dry room (15°C–25°C) at 40%–60% SoC. Ni-MH cells experience natural self-discharge; replenish with a full 0.1C refresh cycle every 90 days to prevent passivating layers on the negative electrode.
