EVE 21700-50E 2S Battery Pack 7.4V 5000mAh 15A for RC Cars & Drones – with T Plug & XH2.54 Balance Lead
Description
High-capacity power for your RC adventures.
This EVE 21700-50E 2S Battery Pack is assembled with two genuine EVE 21700-50E high-capacity cells in series (2S1P). It delivers a nominal 7.4V voltage (8.4V full charge) and a massive 5000mAh capacity, with a 15A continuous and 30A instantaneous discharge capability.
Designed specifically for RC cars, drones, boats, and airplanes, it comes pre-wired with a standard T Plug (Deans) for your ESC and an XH2.54 3-pin balance lead for safe, balanced charging.
Important: This is an unprotected custom pack. You must use a balance charger (set to 2S Li-ion) and ensure your ESC has a low-voltage cutoff (set to 2.5V per cell) to prevent over-discharge.
Key Features
Massive Capacity (5000mAh): Provides significantly longer runtime than standard 2S LiPo packs of similar weight.
15A Continuous / 30A Peak Output: The EVE 50E cells deliver reliable current for moderate-to-high-power RC applications.
T Plug & Balance Lead: Pre-wired with a T Plug (Deans) for your ESC and an XH2.54 3-pin balance lead for safe charging.
Genuine EVE 21700 Cells: High-quality, high-capacity 21700 cells offer excellent cycle life and stable voltage under load.
Compact 2-Cell Layout: Shrink-wrapped in a 2x1 configuration (approx. 72mm x 44mm x 22mm), fitting standard 2S battery compartments.

Applications
Recommended For:
1/10 RC Cars & Trucks: Ideal for standard 2S setups requiring T Plug connections.
RC Drones & Airplanes: Reliable power for flight controllers and motors drawing within 15A continuous.
RC Boats: Stable 7.4V power source for standard marine setups.
DIY RC Projects: Plug-and-play with standard hobby chargers and ESCs.
Not Recommended For:
High-Power RC Models (>15A Continuous): For 1/8 scale cars or high-performance drones drawing 25A+, use a dedicated high-C-rate LiPo pack (e.g., 50C+).
Devices Requiring Protected Batteries: This pack has no built-in BMS. Do not use in devices that lack their own low-voltage cutoff.
FAQ
Q1: Is this battery protected?
A: No, this is an unprotected bare cell pack. It relies on your ESC's low-voltage cutoff and your balance charger for safety. Never discharge below 5.0V (2.5V per cell).
Q2: How do I charge this pack?
A: Use a standard Li-ion/LiPo balance charger. Set it to 2S (7.4V) and a charge current of 2.0A to 5.0A (1C max recommended for longevity). The XH2.54 balance lead allows your charger to balance the two cells.
Q3: What is the difference between the T Plug and XT60?
A: T Plug (Deans) is a very common connector in RC cars. It is rated for moderate currents. Ensure your ESC has a matching T Plug.
Q4: Can I use this for my power tool?
A: No. Power tools typically require 20A+ continuous and have different connectors. This pack is specifically designed for RC hobby applications.
Q5: What are the dimensions?
A: The pack measures approximately 72mm (Length) x 44mm (Width) x 22mm (Height), excluding the wire length.
Payment & Security
Your payment information is processed securely. We do not store credit card details nor have access to your credit card information.
Verified the wiring order before plugging into my charger and it was correct.
The balance wires are wrapped neatly and do not chafe against the main leads.
Fits a 1/16 buggy and delivers enough punch for the stock motor.
Ran it at about 5C and it still delivered usable power. Slight drop, as expected.
Compared to my old unbalanced pack, this one runs cooler and lasts longer per charge.
