3.6V 4000mAh C Ni-MH battery for underwater vacuum cleaner

Hermetically sealed underwater robots face internal pressure risks from battery heat. This 3.6V 4000mAh NiMH C-cell pack features low internal resistance (≤55mΩ) to minimize energy loss as heat. It is a safer, more stable alternative to lithium for submersed suction motors. This pack solves the critical problem of motor efficiency and safety in watertight pool cleaners, providing high energy density for extended cleaning missions.

• Low Internal Resistance: ≤55mΩ design maximizes energy efficiency and reduces heat in sealed housings.
• High Current Delivery: Engineered to handle the sustained high-load demands of underwater suction motors.
• Robust Capacity: 4000mAh rating for extended cleaning missions in residential and commercial pools.
• Submersion Optimized: Stable chemistry designed for safety in watertight, pressurized environments.
• Fast Charging: Supports 0.5C quick-charge protocols to maximize equipment uptime.
