Safety Information and Warnings

Please read all safety instructions carefully before installation or use. Failure to follow these instructions may result in serious injury, property damage, or electric shock.

• ⚠ WARNING: A damaged lithium iron phosphate battery must not be installed or used under any circumstances. Immediately after unpacking, the lithium iron phosphate battery must be inspected for any damage. If the lithium iron phosphate battery is damaged, please contact your reseller.
• ⚠ WARNING: An external charge of the lithium iron phosphate battery must only be carried out with chargers recommended by the battery manufacturer.
• ⚠ WARNING: The lithium iron phosphate battery must never be short-circuited.
• ⚠ WARNING: In case of undervoltage tripping, the lithium iron phosphate battery must be recharged as soon as possible.
• ⚠ WARNING: When using the lithium iron phosphate battery, the parameters mentioned in the technical data sheet for the use of lithium iron phosphate batteries must always be respected.
• ⚠ WARNING: A lithium iron phosphate battery must never be overcharged, as this would permanently damage the battery. Only chargers with an automatic charge stop function should be used.
• ⚠ WARNING: If the lithium iron phosphate battery becomes too hot during charging, the charging process must be interrupted.
• ⚠ WARNING: The charging current must not exceed the maximum charging current indicated on the technical data sheet.
• ⚠ WARNING: The lithium iron phosphate battery must be charged before use. When the charger is no longer used, the lithium iron phosphate battery must be disconnected from the charger.
• ⚠ WARNING: To ensure a long lifespan of the lithium iron phosphate battery and ensure safety, a charger allowing the parameters mentioned in the technical data sheet to be adjusted must be used. Other chargers should only be used if it is certain that the charging voltage does not exceed the charging voltage limits of the lithium iron phosphate battery at any stage of the charge.
• ⚠ WARNING: DO NOT DISASSEMBLE: Never disassemble these cells. Disassembly can lead to an internal short circuit in the cell, which may result in gas production, inflammation, an explosion, or other problems.
• ⚠ WARNING: ELECTROLYTE IS HARMFUL: Normally, there should be no liquid electrolyte from Li-Fe batteries, but if electrolyte comes into contact with skin or eyes, it is necessary to immediately dilute with fresh water and consult a doctor.
• ⚠ WARNING: DO NOT THROW CELLS INTO WATER: Do not immerse the battery in liquids such as water, sea water, non-alcoholic beverages, fruit juices, coffee, or other beverages.
• ⚠ WARNING: DO NOT USE DAMAGED CELLS: If abnormal cell properties are observed, such as damage to the plastic casing or the cell, deformation of the cell pack, an electrolyte odor, electrolyte leakage, and other abnormalities, the cells must no longer be used. Cells that smell of electrolyte or are leaking must be kept away from fire to prevent inflammation or explosion.
• ⚠ WARNING: DO NOT USE IN CERTAIN LOCATIONS: Do not use the battery in places with a strong magnetic field, as this could easily damage the battery's safety protection device and create hidden dangers.

Maintenance

Redodo LiFePO4 batteries are designed for low maintenance. However, regular checks can help ensure optimal performance and longevity:

• Keep terminals clean and free of corrosion.
• Ensure all connections are secure.
• Store the battery in a cool, dry place when not in use for extended periods.
• Avoid exposing the battery to extreme temperatures.
• Charge the battery before long-term storage and periodically during storage to maintain charge.

Troubleshooting

If you encounter issues with your Redodo battery, consider the following common troubleshooting steps:

• Battery not charging:
  • Verify the charger is specifically designed for LiFePO4 batteries and is functioning correctly.
  • Check all cable connections for looseness or corrosion.
  • Ensure the battery's BMS has not triggered a protection mode (e.g., due to over-discharge or over-temperature).
• Battery not providing power:
  • Check the battery's state of charge. It might be deeply discharged.
  • Inspect all connections to the load for proper contact.
  • Confirm the load's power requirements do not exceed the battery's continuous discharge current or the BMS's limits.
• Unusual heat or smell:
  • Immediately disconnect the battery from all loads and chargers.
  • Contact Redodo customer support. Do not attempt to open or repair the battery.
