Specifically designed for heavy-duty portable devices, this pre-wired battery pack is the ultimate drop-in replacement for broken or worn-out batteries in portable blenders, juicers, vacuum sealers, and other small home appliances. It comes with pre-soldered connection wires, saving you the trouble of complicated spot welding and making your DIY repair project simple and straightforward.
Critical Size and Polarity Warnings:
Size Alert: This is a pre-assembled 2-cell parallel battery pack. The physical dimensions are 36mm (Width) x 52mm (Height). Please measure your device's internal battery compartment to ensure it can accommodate the 36mm width before purchasing.
Polarity Alert: This battery pack comes with pre-wired connection cables (+ and -). Please verify the polarity of your original device's circuit board before soldering the wires. Connecting reverse polarity will permanently damage your device.
Key Features:
Massive 4000mAh Capacity (2P Configuration): Two 2000mAh cells connected in parallel double the total capacity, providing long-lasting power for high-consumption appliances.
12A High-Drain Performance: The combined 3C discharge rate of the two cells delivers a stable 12A continuous current, ensuring your blender motor or vacuum runs at peak power.
Pre-Wired and Ready to Install: Comes with pre-soldered wires, eliminating the need for complex spot welding. Simply connect the leads to your device's PCB.
High-Quality 18500 Cells: Built with premium lithium-ion chemistry, low internal resistance (less than or equal to 25mOhm), and 500+ recharge cycles for excellent longevity.
Perfect for Appliance Repairs: An ideal replacement battery pack for portable blenders, juicers, and small cordless home tools.

FAQ:
Q: What does "2P" or "Parallel" mean in this battery pack?
A: 2P means two batteries are connected side-by-side in a parallel circuit. This keeps the voltage at 3.7V but doubles the total capacity to 4000mAh and doubles the discharge current to 12A, providing much longer runtime for your blender.
Q: Is this battery pack ready to install out of the box?
A: Yes. The battery pack comes pre-assembled and pre-wired with soldered leads. You do not need a spot welder. However, you will need a soldering iron to attach the wires to your device's internal motherboard.
Q: Will this fit my blender? What if my device uses a different battery size?
A: This pack is 36mm wide, which is roughly the width of two 18500 cells side-by-side. It is NOT suitable for standard flashlight slots. Please remove your old battery pack, measure its width and height, and compare it to our dimensions before ordering.
Q: How do I know which wire is positive (+) and which is negative (-)?
A: The wires are clearly labeled or color-coded (usually Red for positive, Black for negative). Please check the polarity markings on your device's circuit board before soldering to avoid reverse polarity damage.
Q: Can I use this battery pack to replace a 7.4V (2S) battery in my device?
A: No. This is a 3.7V parallel battery pack. If your original battery was a 7.4V (2S) pack, this lower voltage will not power your device and may trigger low-voltage protection. Please check your original battery's voltage carefully before buying.
