Important Notice: Wiring & Dimensions
This product is a 32700 1S2P (2 cells in parallel) LiFePO4 battery pack. It comes with a built-in BMS protection board and pre-soldered red and black lead wires.
Key Note: The wire ends come without connectors. Red is Positive (+), Black is Negative (-). You will need to solder or crimp your own terminals based on your device's requirements.
Physical Dimensions: 66mm (Width) × 72mm (Height). (Height includes the protection board, which is approx. 2mm taller than standard cells. Please verify your device compartment space before purchasing).
Product Description
3.2V 12Ah Massive Capacity, Safe Plug-in Power
This 3.2V 12000mAh LiFePO4 parallel battery pack combines two high-quality 32700 Grade A cells (1S2P). It comes standard with a built-in BMS to prevent overcharge, over-discharge, overcurrent, and short circuits, ensuring safety and longevity. With a stable 3.2V output and a massive 12Ah capacity, it is ideal for DIY devices requiring high capacity at low voltage, such as solar street lights, outdoor power stations, and custom high-power lighting.
Key Features
-
Massive 12Ah True Capacity: Two premium 6000mAh cells are combined in parallel to deliver a true 12000mAh capacity (38.4Wh), ensuring extended runtime.
-
Built-in BMS Protection: Integrated with a safety BMS board to prevent battery damage and hazards caused by overcharging, over-discharging, and short circuits.
-
Ready-to-Use Wires: Pre-soldered red and black power wires are attached. No need to spot-weld the cells yourself; simply connect the wires to your device (please attach your own connector).
-
Compact Parallel Design: With dimensions of 66mm (W) x 72mm (H), it is easy to fit into various DIY device battery compartments.
-
Ultra-Long LiFePO4 Lifecycle: Built with stable LiFePO4 chemistry, offering significantly longer cycle life and superior cost-effectiveness compared to traditional lithium cells.

FAQ
Q: Why doesn't the battery come with a connector?
A: For maximum DIY freedom. Connectors (such as SM, JST, DC barrels) vary significantly by device. By providing bare wires, you can match the exact connector needed for your specific project, avoiding mismatched terminals.
Q: What happens if I connect the red and black wires reversed?
A: The BMS has reverse-polarity protection, but forcing a connection with reversed wires may still damage the board. Please strictly follow: Red wire to the device's positive (+), Black wire to the device's negative (-).
