High-drain power in a lightweight, custom-wired pack for your RC models and DIY projects.
This EVE 25P 2S 18650 Battery Pack is a custom-assembled pack featuring two genuine EVE 18650-25P high-rate cells connected in series (2S1P). It delivers a nominal 7.4V voltage (8.4V full charge) and a 2500mAh capacity, with a powerful 12C high-drain capability.
It comes pre-wired with a standard XT30 female plug for power output and an XH2.54 3-pin balance lead for safe balanced charging.
CRITICAL SAFETY WARNING: This is an UNPROTECTED pack (No BMS).
-
No built-in protection board.
-
You MUST use a balance charger set to 2S (8.4V max).
-
Your device MUST have a low-voltage cutoff (set to 2.5V per cell / 5.0V total) to prevent over-discharge.
-
Overcharging or over-discharging this battery will permanently damage it and may cause a fire.
Key Features
Genuine EVE 25P Cells: Authentic 12C high-rate cells deliver reliable, high-current output.
XT30 & Balance Lead: Pre-wired with an XT30 female connector for power and an XH2.54 3-pin balance lead for charging.
12C High Discharge: Provides excellent burst power for RC cars, drones, and custom high-drain devices.
Compact 2-Cell Layout: Shrink-wrapped in a 2x1 configuration, measuring approx. 69mm (L) x 37mm (W) x 18.4mm (D).
Unprotected & Lightweight: Designed for advanced users who prefer to rely on their device's ESC and a balance charger for safety.
Parameters
*Dimensions are approximate and include the heat shrink wrap. Please allow ±1-2mm tolerance.
Applications
Recommended For:
RC Cars & Drones: Ideal for small-to-medium RC models using XT30 connectors.
DIY High-Drain Projects: Custom builds requiring a lightweight 7.4V pack with 12C burst capability.
Airsoft & Small RC Boats: Suitable for setups drawing within the continuous limits (requires ESC with LVC).
Not Recommended For:
Devices Without Low-Voltage Protection: Never use in devices lacking a built-in cutoff.
High-Power RC Models (>12C Continuous): For 1/8 scale cars or high-performance drones, use a dedicated high-C-rate LiPo pack.
Beginners: If you are not experienced with balance chargers and unprotected Li-ion packs, do not buy this product.
FAQ
Q1: Is this battery protected?
A: No. This is an unprotected pack with no BMS. You must use a balance charger and ensure your device has a low-voltage cutoff to prevent over-discharge.
Q2: How do I charge this pack?
A: Use a standard Li-ion/LiPo balance charger. Set it to 2S (7.4V/8.4V) and a charge current of 1.0A to 2.5A. The XH2.54 balance lead allows your charger to balance the two cells.
Q3: What is the difference between the XT30 and T Plug?
A: XT30 is smaller than a T Plug or XT60, making it ideal for compact RC models, drones, and micro builds.
Q4: Can I use this for my power tool?
A: No. Power tools typically require 20A+ continuous and have different connectors. This pack is designed for RC and DIY applications.
Q5: What are the dimensions?
A: The pack measures approximately 69mm (Length) x 37mm (Width) x 18.4mm (Height), excluding the wire length.
