Safe 9.6V power with double the capacity for your 9V devices and DIY projects.
This 18650 LiFePO4 (Lithium Iron Phosphate) Battery Pack features six cells arranged in a 3S2P configuration (3 in series, 2 in parallel) within a compact rectangular layout. It delivers a stable 9.6V nominal voltage (10.95V full charge) and a doubled 3600mAh 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. It is an excellent rechargeable replacement for 6-cell AA/alkaline battery packs (9V) or devices requiring a 9V power source with extended runtime. It comes fully assembled with a built-in protection board (BMS) and pre-wired with red (positive) and black (negative) leads.
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
LiFePO4 Chemistry: High thermal stability, excellent safety, and an ultra-long cycle life.
3S2P Configuration (9.6V / 3600mAh): Offers both the 9V voltage you need and double the capacity for longer runtime.
Compact 2x3 Rectangular Layout: Space-saving design (approx. 67mm x 56mm x 36mm) ideal for tight enclosures.
Built-in Protection Board (BMS): Protects against overcharge, over-discharge, over-current, and short circuits.
Pre-wired & Ready to Use: Comes with red (+) and black (-) leads for quick connection.
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.
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: What does "3S2P" mean?
A: It means 3 cells in series (to triple the voltage to 9.6V) and 2 cells in parallel (to double the capacity to 3600mAh).
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.
