Product Overview

The FMA 14.8V 2500mAh High-Drain Li-ion Battery Pack is built using genuine SONY US18650VTC5A high-drain cells, engineered specifically for high-power applications requiring continuous massive current output up to 35A. Perfect for robot vacuum cleaners, high-speed RC models, motorized equipment, and demanding DIY power systems.

This pack features an intelligent dual-circuit architecture tailored for high-discharge performance: charging is safe and regulated through a built-in PCM, while discharging bypasses the protection board to eliminate current bottlenecks.

⚡ Dual-Port Architecture & Discharge Notice

  • DC 5.5 / 2.1mm Female Port (Charging Port): Routed through the internal PCM protection circuit to safeguard against overcharging during the charge cycle.
  • T-Plug / Deans Connector (Discharge Port): Wired directly to the battery cell terminals, bypassing the protection board. This allows unrestricted, ultra-high current delivery up to 35A.
  • ⚠️ Important Notice on Over-Discharge: Because the discharge port has no PCM cut-off, it provides no built-in low-voltage protection. Users must ensure their device has a built-in low-voltage （no less than 11.2V) cutoff or monitor battery voltage during use to prevent cell over-discharge.

Safety Information

  • Charging: Charge exclusively through the dedicated DC 5.5/2.1mm port using a compatible Li-ion charger. Never attempt to charge the pack via the unprotected T-plug. Never leave charging batteries unattended.
  • Over-Discharge Warning: Discharging through the T-plug bypasses the internal protection module. Do not allow the pack voltage to drop below safe operating limits. Always use with a low-voltage alarm or devices featuring built-in cutoff circuits.
  • Handling & Storage: Store in a cool, dry place (15°C–25°C) away from direct sunlight, open flames, and heat sources. Keep battery at 40%–60% charge for long-term storage.
  • Operation: Do not short-circuit, crush, puncture, or submerge the battery pack in water or other liquids.
  • Temperature: Operate within 0°C to 45°C. Do not operate or charge in freezing or severely elevated temperatures.
  • Disposal: Recycle responsibly in accordance with local lithium-ion battery regulations. Do not dispose of in household trash or incinerate.
  • Inspection: Immediately discontinue use if the battery shows physical deformation, swelling, unusual odors, or excessive heating during operation.

Shipping & Transportation Notice
