Battery Operations

⚡ Charging

  • Use only a charger designed for lithium-ion or LiFePO4 battery packs — never use a lead-acid charger.
  • Always verify correct polarity before connecting. Do not reverse the positive (+) and negative (−) terminals.
  • Connect the charger’s output cable to the battery’s charging port first, then plug into the wall outlet.
  • When charging is complete, disconnect from the wall outlet first, then remove the output plug from the battery.

Note: The LiFePO4 charger is for charging only — do not use it as a power supply or charging station for other devices.

🔋 Discharging

  • Ensure the battery’s positive and negative terminals are properly connected to the matching load.
  • Always verify correct polarity before connection. Do not reverse polarity.
  • The current ratings in the specifications represent recommended operating limits for optimal performance and service life — they are not intended to define instantaneous safety disconnect thresholds.
  • The internal BMS protects the battery from extreme electrical and thermal conditions. In certain scenarios, discharge currents above the recommended range may occur without an immediate BMS shutdown. In these cases, thermal protection and external system safeguards are relied upon to prevent sustained operation outside recommended conditions.

Safety & Handling Precautions

🌡️ Temperature & Environment

  • Operate and store the battery within the specified temperature limits.
  • Do not expose the battery to open flames, heaters, or corrosive materials.
  • If ambient temperature exceeds 45°C (113°F), ensure adequate airflow for ventilation.
  • Keep the battery dry and protected from condensation, high humidity, or flooding.

🔌 Installation

  • Install in compliance with all applicable national and local electrical codes.
  • Do not install if there are any signs of physical damage.
  • Avoid areas that may be exposed to standing water or flooding.
  • Use insulated tools during installation to reduce electrical shock hazards.

⚠️ Do Not

  • Use a lead-acid charger — only use LiFePO4-compatible chargers.
  • Over-discharge below 8V — BMS will cut off, but deep discharge shortens battery life.
  • Use for cold cranking (engine starting) — this battery is not designed for that.
  • Disassemble, modify, or attempt to repair the battery yourself.
  • Short-circuit the terminals.
  • Crush, puncture, drop, or apply excessive pressure to the battery.
  • Expose to strong static discharge or magnetic fields.
  • Continue use if the battery emits odor, heat, swelling, or other abnormal behavior — stop immediately.

🚨 Emergency Response

  • Disconnect the battery from all systems before handling in an emergency.
  • Wear appropriate protective equipment: gloves, eye protection, and a respirator when necessary.
  • Use an ABC type dry chemical or lithium-specific fire extinguisher, or dry sand to extinguish flames.

Disposal

Cover battery terminals with non-conductive tape before disposal. Recycle unused or retired batteries and packaging materials at an authorized recycling center. Ensure disposal complies with all local environmental regulations.
