Safe 9.6V power for your 9V devices and DIY projects.
This 32700 LiFePO4 (Lithium Iron Phosphate) Battery Pack features three large-format cells connected in series (3S), delivering a stable 9.6V nominal voltage (10.95V full charge) and a 5000mAh capacity.
Unlike standard 3.7V Li-ion cells, LiFePO4 chemistry offers superior thermal stability, an ultra-long cycle life, and a much lower risk of fire or explosion. The 32700 form factor (approx. 32mm diameter per cell) is ideal for replacing 6-cell AA/alkaline battery packs (9V) in portable devices, sensors, toys, and custom 9V projects. It comes fully assembled with a built-in protection board (BMS) and pre-wired with red (positive) and black (negative) leads. Note: The wire ends are bare (no connector attached).
CRITICAL WARNING: Voltage Compatibility
This is a 3S LiFePO4 battery (9.6V nominal). You MUST use a dedicated LiFePO4 charger with a 10.95V (approx. 11V) cutoff. Never use a standard 3S Li-ion charger (12.6V) or a single-cell charger, as it will overcharge the battery and cause permanent damage or fire.
Key Features

Parameters
*Dimensions are approximate and include the protection board and heat shrink wrap. Please allow ±1-2mm tolerance.
Applications
Recommended For:
9V Devices: Perfect replacement for devices using 6x AA/alkaline batteries (6x 1.5V = 9V).
DIY 9.6V Projects: Custom electronics requiring a stable 9V-9.6V power source.
Emergency Lighting: Reliable, safe power for low-drain emergency lamps.
Portable Instruments: Suitable for sensors, meters, and portable testing equipment.
Not Recommended For:
Devices Requiring 11.1V/12.6V: This battery will not work properly in standard 3S Li-ion devices due to the lower voltage.
High-Drain Power Tools: Not suitable for tools requiring high burst currents.
Standard Li-ion Chargers: Never charge this with a 12.6V or 4.2V charger.
FAQ
Q1: Can I use my standard 3S Li-ion charger (12.6V) for this battery?
A: NO. You must use a dedicated LiFePO4 charger with a 10.95V (approx. 11V) cutoff. Using a 12.6V charger will overcharge and damage the battery, potentially causing a fire.
Q2: Why is the voltage 9.6V? I thought 3S was 11.1V.
A: This is a LiFePO4 battery, not a standard Li-ion battery. LiFePO4 cells have a nominal voltage of 3.2V (3.2V x 3 = 9.6V), with a max charge of 10.95V. Standard Li-ion is 3.7V/4.2V.
Q3: Does it come with a connector?
A: No. The battery comes with bare red and black wires. You will need to solder or attach your own connector based on your device's requirements.
Q4: Can I use this to replace 9V batteries?
A: Yes, it is an excellent replacement for 6x AA batteries (6x 1.5V = 9V) in devices like toys, sensors, and small motors, provided the physical dimensions fit.
Q5: How should I connect the wires?
A: The red wire is positive (+) and the black wire is negative (-). Ensure correct polarity when connecting to your device.
