Description
Push the limits of power and endurance with the EVE 50PL, a tabless 21700 cell that redefines what a battery can do. This 4-pack delivers an unprecedented combination of 5000mAh capacity, a massive 70A continuous discharge, and an astonishing 125A pulse rating. Engineered for the most extreme applications — FPV drones, heavy-duty power tools, high-performance e-scooters, and competition-level — the 50PL eliminates voltage sag with its ultra-low internal resistance of just ~5mΩ. The flat top design fits all standard 21700 spring-contact devices and is ideal for spot-welding into custom high-current packs. When you refuse to choose between capacity and power, the EVE 50PL is the only answer.
Key Features
-
70A Continuous / 125A Pulse Discharge – True 70A continuous current handles the most power-hungry motors and coils. Pulse capability up to 125A provides explosive bursts for FPV punch-outs and tool start-ups.
-
5000mAh Massive Capacity – Industry-leading energy density for a high-drain cell. Enjoy significantly longer flight times, ride ranges, and work sessions compared to 4000mAh cells.
-
25C Tabless (All-Tab) Technology – Reduces internal resistance to ~5mΩ. Minimizes heat build-up, maximizes power delivery, and keeps voltage rock-steady under extreme loads.
-
Flat Top Design – Universally compatible with 21700 spring-contact chargers, battery trays, and flashlights. The flat terminal is perfect for spot-welding nickel strips in DIY packs.
-
4-Pack Convenience – Ideal for building a high-current 4S FPV pack, equipping a dual-battery mod, or powering a compact e-scooter battery module.
-
EVE A-Grade Quality – Rigorous testing ensures consistent capacity, low self-discharge, and reliable cycle life trusted by professionals worldwide.
Parameters
Applications
Recommended For
-
FPV Drones & Long-Range UAVs: 125A pulse handles aggressive punch-outs and acrobatic maneuvers. 5000mAh capacity extends flight time far beyond LiPo packs of similar weight.
-
High-Performance E-Scooters & E-Bikes: Build compact, high-power battery modules (e.g., 10S1P or 12S1P) with fewer parallel cells needed thanks to the high capacity and 70A continuous rating. Always use a quality BMS.
-
Heavy-Duty Cordless Power Tools: Angle grinders, circular saws, rotary hammers, and chain saws operate at peak torque without voltage sag or thermal throttling.
-
Competition-Level Vaping: Super-sub-ohm mechanical mods and high-wattage regulated devices (builds down to ~0.05Ω) benefit from the near-zero voltage drop and immense pulse headroom.
-
Extreme-Output Flashlights: FET-driven multi-emitter searchlights and hot-rod torches can sustain turbo modes at 40–60A with constant brightness.
-
Professional RC Racing: Cars, boats, and planes that demand instantaneous 100A+ bursts off the starting line.
-
DIY High-Current Projects: Portable spot welders, high-power inverters, and any project where maximum current and capacity are both critical.
Not Recommended For
-
Low-Power Long-Runtime Devices: Solar lights, wireless sensors, and doorbells. The 50PL is severe overkill; use a Samsung 50G (5000mAh 10A) for better economy.
-
18650-Only Devices: This is a 21700 cell (21mm x 70mm) and will not physically fit.
-
Standard USB Power Banks: The extreme performance is completely wasted in low-current applications.
FAQ
Q: What is the real continuous discharge — 70A or 60A? Some sources differ.
A: The EVE 50PL is officially rated for 70A continuous. However, many professional pack builders design to a 60A continuous ceiling to maximize cycle life and keep cell temperatures well within safe limits. For short, intense bursts, the cell can handle up to 125A. If you intend to run at 70A continuously, ensure excellent active cooling.
Q: Can I use this battery for my FPV drone? How does it compare to LiPo?
A: Yes, the 50PL is a game-changer for FPV. While a LiPo can deliver extreme bursts, a 4S 50PL pack provides far greater energy density (5000mAh vs. ~1500mAh for a similar-weight LiPo), giving you dramatically longer flight times. The 125A pulse ensures you still get explosive throttle response.
Q: Is this battery suitable for vaping? What resistance is safe?
A: Yes, it is a top-tier choice for extreme sub-ohm vaping. With 70A continuous and 125A pulse at 3.6V nominal, it can safely power builds down to approximately 0.05Ω. Always calculate your exact current using Ohm's law, and never exceed the pulse rating for more than a few seconds.
Q: What is tabless technology and why does it matter?
A: A tabless cell eliminates the thin metal tabs that connect the electrode layers inside the battery. Instead, the entire edge of the electrode connects directly to the terminal. This dramatically lowers internal resistance (~5mΩ), reduces heat, and allows for much higher currents with less voltage sag — essential for FPV and power tools.
Q: Do I need a special charger for tabless cells?
A: No special charger is required. The 50PL charges like any standard 21700 Li-ion cell. Use a quality CC-CV charger. Charging at 0.5C (2.5A) is recommended for longevity, though the cell can accept up to 5A.
