Safe 6.4V power with triple the capacity for your 6V devices and DIY projects.
This 32700 LiFePO4 (Lithium Iron Phosphate) Battery Pack features six large-format cells arranged in a 2S3P configuration (2 in series, 3 in parallel) in an inline layout. It delivers a stable 6.4V nominal voltage (7.3V full charge) and a massive 15000mAh 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 4-cell AA/alkaline battery packs (6V) in solar lights, toys, portable devices, and custom 6V projects. The inline layout (194mm length) is perfect for long, narrow battery compartments. 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 2S LiFePO4 battery (6.4V nominal). You MUST use a dedicated LiFePO4 charger with a 7.3V cutoff. Never use a standard 2S Li-ion charger (8.4V) or a single-cell charger, as it will overcharge the battery and cause permanent damage or fire.
Key Features

Inline Layout: Long, robust design (approx. 194mm length) ideal for narrow battery bays.
Built-in Protection Board (BMS): Protects against overcharge, over-discharge, over-current, and short circuits.
Pre-wired Leads: Comes with red (+) and black (-) wires. No connector is attached (bare wire ends).
Parameters
*Dimensions are approximate and include the protection board and heat shrink wrap. Please allow ±1-2mm tolerance.
Applications
Recommended For:
6V Solar Lights: The ideal replacement battery for outdoor solar path lights and lawn lamps requiring longer runtime.
6V Devices: Perfect replacement for devices using 4x AA/alkaline batteries (4x 1.5V = 6V).
DIY 6.4V Projects: Custom electronics requiring a stable 6V-6.4V power source.
Emergency Lighting: Reliable, safe power for low-drain emergency lamps.
Not Recommended For:
Devices Requiring 7.4V/8.4V: This battery will not work properly in standard 2S Li-ion devices due to the lower voltage.
Standard Small Battery Bays: Due to the 194mm length, please measure your enclosure carefully to ensure it fits.
Standard Li-ion Chargers: Never charge this with an 8.4V or 4.2V charger.
FAQ
Q1: Can I use my standard 2S Li-ion charger (8.4V) for this battery?
A: NO. You must use a dedicated LiFePO4 charger with a 7.3V cutoff. Using an 8.4V charger will overcharge and damage the battery, potentially causing a fire.
Q2: Why is the voltage 6.4V? I thought 2S was 7.4V.
A: This is a LiFePO4 battery, not a standard Li-ion battery. LiFePO4 cells have a nominal voltage of 3.2V (3.2V x 2 = 6.4V), with a max charge of 7.3V. Standard Li-ion is 3.7V/4.2V.
Q3: What does "2S3P" mean?
A: It means 2 cells in series (to double the voltage to 6.4V) and 3 cells in parallel (to triple the capacity to 15000mAh).
Q4: 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.
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.
