Massive 50,000mAh capacity in an extra-long inline layout, with ultimate safety.
This 32700 LiFePO4 (Lithium Iron Phosphate) Battery Pack features ten large-format cells connected in parallel (10P) in a linear configuration. It delivers a stable 3.2V nominal voltage (3.65V full charge) and a staggering 50000mAh (50Ah) 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 massive solar street lights, large RV energy storage systems, industrial power stations, and replacing large lead-acid batteries. The extra-long inline layout (322mm length) is designed for long, wide 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 LiFePO4 battery (3.2V nominal). You MUST use a dedicated LiFePO4 charger with a 3.65V cutoff. Never use a standard 3.7V/4.2V Li-ion charger, as it will overcharge the battery and cause permanent damage or fire.
Key Features

Applications
Recommended For:
Massive Solar Street Lights: The staggering capacity makes it perfect for large outdoor solar lighting systems.
RV & Off-Grid Storage: Ideal for building large custom 3.2V power banks or battery packs for camping, RVs, and portable power stations.
Replacing Lead-Acid Cells: A lightweight, long-lasting alternative for large 3V/4V lead-acid batteries.
Industrial Electronics: Suitable for large devices requiring a stable 3.2V power source.
Not Recommended For:
Devices Requiring 3.7V/4.2V: This battery will not work properly in standard Li-ion devices due to the lower voltage.
Standard Small Battery Bays: Due to the 322mm length, please measure your enclosure carefully to ensure it fits.
Plug-and-Play Applications: Since there is no connector on the wires, you must have soldering or wiring skills to connect it to your device.
Standard Li-ion Chargers: Never charge this with a 4.2V charger.
FAQ
Q1: Can I use my standard 3.7V Li-ion charger for this battery?
A: NO. You must use a dedicated LiFePO4 charger (3.65V cutoff). Using a 4.2V charger will overcharge and damage the battery, potentially causing a fire.
Q2: Why is the voltage 3.2V? My other batteries are 3.7V.
A: This is a LiFePO4 battery, not a standard Li-ion battery. LiFePO4 cells have a nominal voltage of 3.2V and a max charge of 3.65V. They are safer and last longer, but cannot be used interchangeably with 3.7V devices.
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: What are the dimensions?
A: The ten cells are arranged inline, measuring approximately 322mm (Width) x 32mm (Depth) x 72mm (Height). Please verify this fits your battery compartment.
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.
