APPLICATIONS
Lithium Iron Phosphate can be used in most applications that use Lead Acid, GEL or AGM type batteries.
Suitable applications include:
• Fishing sonar
• Electrical devices
• Toys
• Emergency light
• Digital camera
• Remote Monitoring
• Switching applications and more
CAUTIONS
• Do NOT short circuit, crush or disassemble.
• Do NOT heat or incinerate.
• Do NOT immerse in any liquid.
• Store at 30~50% SOC. Recharging every 3 months is recommended. The storage area should be clean, cool, dry and ventilated.
