High-drain power for your custom DIY battery packs.
This EVE 25P 3S 18650 Battery Pack is a pre-assembled bare cell configuration, featuring three genuine EVE 18650-25P high-drain cells connected in series (3S1P) with spot-welded nickel tabs. It delivers a nominal 11.1V voltage (12.6V full charge) and a 2500mAh capacity, with a powerful 30A continuous discharge (12C) capability.
This product is designed specifically for experienced DIY builders who require a compact, high-current power source for custom projects.
IMPORTANT: This is a BARE CELL PACK.
-
No BMS (Protection Board) is included.
-
No wires or connectors are attached.
-
You must have the skills to spot-weld/solder your own connections and install an external 3S BMS before use. Never use or charge this pack without proper protection.

Applications
Recommended For:
DIY Battery Packs: For building custom 12V power packs for robotics, power tools, or portable devices.
RC Models & Airsoft: Suitable for high-current RC cars, boats, or Airsoft AEGs (requires proper wiring and BMS).
Custom High-Drain Projects: Spot welders, portable jump starters, or any project demanding 30A bursts.
Not Recommended For:
Beginners or Plug-and-Play Users: If you cannot spot-weld, solder, and install a BMS, do not buy this product.
Devices Requiring a Finished Pack: This will not fit directly into standard battery compartments without custom wiring.
Vaping (Unprotected): Using bare, unprotected cells in mechanical mods is extremely dangerous and not recommended.
FAQ
Q1: Does this battery have a protection board (BMS)?
A: No. This is a bare cell pack. You must install an external 3S BMS to protect against overcharge, over-discharge, and short circuits.
Q2: Does it come with wires?
A: No. It only includes spot-welded nickel tabs. You will need to solder your own wires or spot-weld your connections.
Q3: What is the actual discharge current?
A: The EVE 25P cells are rated for a continuous discharge of 30A (12C). However, the actual current you can draw will depend entirely on the BMS and wiring you install.
Q4: How do I charge this pack?
A: Once you install a BMS, you must use a dedicated 3S Li-ion charger (12.6V output). Never charge bare cells directly without a BMS.
Q5: What are the dimensions?
A: The three cells are arranged side-by-side, measuring approximately 55.2mm (Width) x 65mm (Height) x 18.4mm (Depth).
