IMPORTANT SAFETY INSTRUCTION

• Please keep the battery away from heat sources, sparks, flames, and hazardous chemicals.

• Maintain Adequate Ventilation and Heat Dissipation
  Place the battery in a well-ventilated area with sufficient heat dissipation to prevent overheating and damage.

• Size the Battery Cables and Connectors Appropriately
  Use high-stranded copper connectors and heavy gauge cables to handle possible battery loads. Make sure to keep identical cable lengths.
  Avoid accidents caused by unsuitable connectors or cables that make the connection a heat source during battery operation.

• Please tighten all cable connections, as loose cable connections can cause terminal meltdown or fire.

• DO NOT puncture, drop, crush, burn, penetrate, shake, or strike the battery.
  The battery should be securely fastened during handling to prevent impact or dropping.
  It should be safely secured to a solid plane and the cables safely tied to a suitable location to avoid arcing and sparking due to friction. DO NOT press it by placing heavy stuff on top of it for long periods, which may damage it due to an internal short circuit.

• DO NOT immerse the battery in water whether the battery is in use or on standby.

• DO NOT open, dismantle, or modify the battery.

• DO NOT touch the exposed electrolyte or powder if the battery casing is damaged.

• Uncovered electrolyte or powder that has contacted the skin or eyes MUST be flushed out with plenty of clean water immediately.
  Seek medical attention afterward.

• Avoid Short Circuit
  Please use circuit breakers, fuses, or disconnects that have been properly sized by certified electricians, licensed installers, or regional code authorities to protect all the electrical equipment in your system. The battery has a built-in battery management system (BMS) that protects the battery cells from over-charge, over-discharge, and over-current, however this alone will not protect your system from severe electrical conditions.

• Trained and certified technicians are required for safe and reliable installation. This product manual can only serve as a guideline as it cannot cover all possible scenarios.

• Verify Correct Polarity
  Please verify the polarity before connecting the wiring. Reverse polarity can and will destroy the battery and other electrical equipment. Use a multimeter to determine proper polarity.

• Avoid Exposed Metal Terminals or Connectors
  The terminals of this battery are always live. Avoid exposed metal terminals or connectors; DO NOT place tools on the terminals or touch them with bare hands; DO NOT short circuit or use outside of specified electrical ratings.

• DO NOT dispose of the battery as household waste. Please use recycling channels in accordance with local, state, and federal regulations.

WARNING

• Batteries are potentially dangerous and proper precautions must be taken during operation and maintenance.
• Improper use of the battery can lead to battery failure or other potential damage.
• Improper configuration, installation, or use of related equipment in the battery system may damage the battery and other related equipment.
• Please wear proper personal protective equipment when working on the battery.
• Battery installation and maintenance must be performed by trained and certified technicians.
• Failure to follow the warnings above can result in potential damage.

THINGS TO KNOW BEFORE USING

• When using the battery, please be careful to avoid metal or conductive objects touching the positive and negative poles of the battery at the same time, otherwise it may cause a short circuit.
• Install the battery upright with post bolt facing up, and it could not be mounted upside down. If you need to mount the battery at its side, please contact service@litime.com to confirm the direction.
• Tightly screw in the post bolts. Having loose battery terminals will cause the terminals to build up heat resulting in damage to the battery.
• This battery is not intended to be used to start any devices, please DO NOT use it as a starting battery.
• Suggestions for Long-term Storage:

Ο Temperature
The battery can be operated at a temperature of -20°C to 60°C / -4°F to 140°F, and a temperature between 10°C to 35°C / 50°F to 95°F is ideal for long-term storage. Store in a fireproof container and away from children.
O Capacity
For a longer-lasting product, it is best to store your battery at a 50% charge level and recharge every three months if it is not going to be used for a long time.

CHARGING METHODS

SOLAR PANEL(S) & CONTROLLER

◼ Solar Panel
Recommend Power: ≥ 800W

• The battery can be fully charged in one day (with effective sunshine 4.5hrs/day) by 800W solar panels.
• It may take more than one day to fully charge the battery by 2800W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

◼ Controller
Recommend Charging Current:

capacity.

Recommend Charging Mode: 24V (29.2V) LI (LiFePO4)

◼ Controller Settings
Refer to the below parameters if you need to manually set up your controller.
As different types of batteries have different charging modes, it is recommended to set only the following parameters for LiFePO4 batteries. The settings for other types of batteries do not apply to LiFePO4 batteries except for the following settings.

BATTERY CHARGER
Use 29.2V lithium iron phosphate (LiFePO4) battery charger to maximize the capacity.

Recommend Charging Voltage: Between 28.4V to 29.2V
Recommend Charging Current:

capacity.

Tips

1. Connect the charger (with alligator clips) to the grid power before connecting it to the battery in case of sparks.
2. It’s recommended to disconnect the charger from the battery after fully charging.

ALTERNATOR / GENERATOR
LiTime battery can be charged by an alternator or generator.
If the alternator/generator supports DC output, a DC-to-DC charger needs to be added between the battery and the generator; if the alternator/generator supports AC output, please refer to the recommendations in “Battery Charger” above to add a suitable battery charger between the battery and the generator.

Recommend Charging Voltage: Between 28.4V to 29.2V
Recommend Charging Current:

capacity.

HOW TO ESTIMATE THE BATTERY CAPACITY

STATE OF CHARGE (SOC)
The battery capacity could be roughly estimated by its resting voltage (not charging/discharging voltage).①
Since the voltage of each battery is slightly different, and the voltage measurement is affected by the measuring instrument, ambient temperature, etc., the following parameters are for reference only. The actual SOC of the battery is based on the discharge  capacity under load.
Resting Voltage: The voltage is measured after the battery has been disconnected from the charger and loads with zero current, and left alone for 3 hours.

1. Based on the characteristics of LiFePO4 batteries, the voltage measured by all LiFePO4 batteries during charging/discharging is not the real voltage of the battery. Therefore, after charging/discharging and disconnecting the battery from the power source, the voltage of the battery will gradually drop/increase to its real voltage.
2. After this battery is protected from overcharge, the tested battery voltage (not the real voltage) will be lower than the real voltage. To calculate the SOC (%), add 0.5V to 0.7V to the tested battery voltage.
