Monster 10,000mAh capacity with maximum safety, ready to plug in.
This EVE 25P 4P 18650 Battery Pack features four genuine EVE 18650-25P high-rate cells connected in parallel (4P) in a compact 2x2 layout, delivering a massive 10,000mAh capacity while maintaining a standard 3.7V nominal voltage (4.2V full charge).
Designed for DIY enthusiasts and extreme long-runtime devices, it comes fully assembled with a built-in protection board (BMS) and pre-wired with a default XH2.54 2-pin connector. The protection board safeguards against overcharge, over-discharge, over-current, and short circuits.
Important: Because of the integrated protection board, the continuous working current is limited to 4A (peak 10A). This pack is the ultimate high-capacity, low-drain power source for IoT nodes, portable sensors, custom power banks, and months-long DIY projects. It is not intended for high-power tools or high-drain flashlights.
Key Features
Monster Capacity (10,000mAh): Four 2500mAh cells in parallel provide quadruple the runtime of a single cell, offering months of standby power for low-drain devices.
Built-in Protection Board (BMS): Comprehensive safety against overcharge, over-discharge, over-current, and short circuits.
Pre-wired & Plug-and-Play: Comes with a default XH2.54 2-pin connector (red/black leads, 8-15cm) for easy integration.
Safe 4A Continuous Current: Specifically designed for low-to-medium current devices. (Max continuous 4A, peak startup 10A).
Compact 2x2 Layout: Shrink-wrapped with the side protection board, measuring approx. 75mm (L) x 65mm (W) x 18.5mm (D).
Parameters
*Dimensions are approximate and include the protection board and heat shrink wrap. Please allow ±1-2mm tolerance.
Applications
Recommended For:
Long-Runtime IoT & Sensors: Months of standby power for remote sensors, LoRa nodes, and wireless monitoring devices.
Portable Devices: Ultra-high-capacity replacement for mini fans, radios, and small wireless modules.
Custom Power Banks: Build a massive 10,000mAh safe power bank with built-in protection.
Low-Power LED Lighting: Suitable for small desk lamps, emergency lights, or camping lanterns drawing under 4A.
Not Recommended For:
High-Drain Devices (>4A): Do not use in high-power flashlights, power tools, or devices drawing more than 4A continuously. The protection board will cut off power.
Vaping/Mechanical Mods: Not suitable for high-current vaping devices.
Devices Requiring Bare Cells: If your device's battery tray expects a standard flat-top cell, this pre-wired pack will not fit.
FAQ
Q1: Does this battery pack have a protection board?
A: Yes, it features an integrated side protection board to prevent overcharge, over-discharge, over-current, and short circuits, ensuring safe operation.
Q2: What is the maximum discharge current?
A: Because of the protection board, the continuous working current is limited to 4A (with a peak of 10A for short startups). It is not designed for high-drain devices.
Q3: Can I use this for a high-power flashlight or power tool?
A: No. High-power flashlights and power tools typically draw 10A to 30A+. The 4A protection limit will cause the board to shut off the battery. Use bare EVE 25P cells for high-power lights.
Q4: What does "4P" mean?
A: "4P" stands for 4 cells in Parallel. This quadruples the capacity (4 x 2500mAh = 10,000mAh) while keeping the voltage at 3.7V.
Q5: Can I change the connector to something else?
A: The default is an XH2.54 2-pin. We can potentially provide other connectors (like JST, PH2.0, or bare wires) upon request. Please contact us before ordering if you need a different connector.
