TATTU 650mAh 2S 7.4V 75C LiPo Battery Pack User Manual

Introduction

Welcome to the user manual for your TATTU 650mAh 2S 7.4V 75C LiPo Battery Pack. This battery is engineered for high-performance applications such as FPV drones and RC models, offering a balance of capacity, discharge rate, and compact size. This manual provides essential information for safe and effective use, including setup, operation, maintenance, and troubleshooting.

Important Safety Instructions and Warnings

Lithium Polymer (LiPo) batteries are powerful energy sources and require careful handling. Failure to follow these instructions can result in fire, personal injury, and property damage. Read and understand all warnings before use.

• Charging: Always use a LiPo compatible charger with balance charging capabilities. Never charge unattended. Do not overcharge or discharge beyond recommended limits.
• Storage: Store LiPo batteries in a fireproof container or LiPo-safe bag, away from flammable materials, direct sunlight, and extreme temperatures.
• Inspection: Inspect the battery for any physical damage, swelling, or exposed wires before each use. Do not use a damaged battery.
• Handling: Do not puncture, disassemble, or modify the battery. Avoid short-circuiting the terminals.
• Disposal: Dispose of damaged or depleted LiPo batteries properly according to local regulations. Never throw them in regular trash.

Setup

Initial Inspection

Upon receiving your TATTU LiPo battery, carefully inspect it for any signs of physical damage, such as dents, punctures, or swelling. Check that all connectors (XT30 and JST-XHR-3P balance plug) are intact and free from corrosion. Do not proceed with use if any damage is observed.

Initial Charging

It is recommended to fully charge the battery before its first use. Follow these steps for safe initial charging:

1. Connect the XT30 discharge plug of the battery to the main output port of your LiPo compatible charger.
2. Connect the JST-XHR-3P balance plug of the battery to the balance port on your charger.
3. Set your charger to the 'LiPo Balance Charge' mode.
4. Configure the charger settings: Voltage to 7.4V (2S) and Charge Current to 0.65A (1C rate for 650mAh).
5. Initiate the charging process and monitor the battery throughout. Discontinue charging immediately if the battery shows any signs of swelling or overheating.

Operating Instructions

Connecting the Battery

Always ensure your device (e.g., FPV drone, RC model) is powered off before connecting the battery to prevent accidental activation or damage.

1. Align the XT30 plug on the battery with the corresponding XT30 receptacle on your device.
2. Firmly push the connectors together until they are fully seated and secure.
3. Ensure the balance lead is tucked away and will not interfere with any moving parts or propellers during operation.

Disconnecting the Battery

To disconnect the battery, first power off your device.

1. Grip the XT30 connector firmly and pull it straight apart. Avoid pulling on the wires, as this can damage the connections.
2. Disconnect the balance lead from any securing mechanism.

Usage Guidelines

• Do not discharge the battery below 3.0V per cell (6.0V for a 2S battery). Over-discharging can permanently damage the battery.
• Avoid continuous current draw exceeding the specified discharge rate of 75C.
• Allow the battery to cool down to ambient temperature before recharging after heavy use.

Maintenance and Storage

Storage

For optimal battery health and longevity, especially during long periods of inactivity, store the battery at a 'storage voltage' of approximately 3.8V per cell (7.6V for a 2S battery). Most modern LiPo chargers have a dedicated storage mode.

• Store batteries in a cool, dry place, away from direct sunlight, heat sources, and flammable materials.
• Always use a LiPo-safe bag or fireproof container for storage.

Cleaning

Keep the battery casing and connectors clean and free from dust, dirt, and moisture. Use a dry, soft cloth to wipe the battery. Do not use liquids or solvents.

Cycle Life

With proper care and adherence to charging/discharging guidelines, the TATTU LiPo battery is designed for a long cycle life, typically 150 cycles minimum.

Troubleshooting

If you encounter issues with your TATTU LiPo battery, refer to the following common problems and solutions:

• Battery Not Charging:
  Ensure your charger is set to the correct LiPo mode (2S, 7.4V) and the charge current is appropriate (0.65A). Check all connections (XT30 and balance plug) for proper seating. Inspect the battery for any visible damage.
• Reduced Performance (Flight Time/Power):
  This could indicate the battery is not fully charged, has been over-discharged in previous uses, or is reaching the end of its useful life. Ensure proper charging practices and avoid deep discharges.
• Battery Swelling:
  If the battery casing appears swollen or puffed, immediately discontinue use. This is a sign of internal damage and a potential safety hazard. Safely discharge the battery to 0V and dispose of it according to local regulations. Do not attempt to charge or use a swollen battery.
• Overheating During Use or Charging:
  Excessive heat can indicate a short circuit, over-discharge, or an issue with the charger. Discontinue use or charging immediately. Allow the battery to cool down and inspect for damage. Ensure your device's current draw does not exceed the battery's capabilities.
