Key Features
- 5000mAh High Capacity: Serious runtime in a cell that doesn't ask you to trade capacity for current — the 50PL delivers both without compromise.
- Extreme 50A Continuous Discharge: 50A continuous from a 5000mAh cell is genuinely impressive — this is the kind of output that separates the 50PL from the field.
- Tabless Cell Design: The tabless architecture cuts internal resistance and keeps heat down, so you get cleaner power delivery and a cooler-running pack under hard use.
- Stable Lithium-Ion Chemistry: Consistent voltage under load and reliable discharge behavior cycle after cycle — exactly what a high-performance build depends on.
- Professional Integration Cell: Unprotected flat-top design built to work with your BMS — full external control for the serious pack builder.
Overview
The EVE 50PL is the kind of 21700 cell that makes high-current builds a lot more straightforward. It pairs a 5000mAh capacity with a 50A continuous discharge rate — a combination that most cells in this format simply can't match — and backs it up with a tabless cell design that keeps internal resistance low and heat generation in check even when you're pulling hard. Whether you're building a high-output e-bike pack, assembling a competitive FPV drone battery, or putting together a custom power tool configuration, the 50PL gives you the current headroom to work with. At 3.6V nominal and approximately 72g, it's a well-proportioned cell that fits standard 21700 hardware and works with the BMS and thermal management setup of your choice. Rated for 400 cycles, it's built to hold up across extended use in demanding conditions — not just perform on the first run.
Applications / Uses
- Electric vehicles and e-bikes where high continuous current directly translates to real-world acceleration and range
- FPV racing drones and RC models pushing maximum continuous and burst power demands
- Heavy-duty cordless power tools including high-torque grinders, saws, and impact drivers
- Robotics and automation builds requiring dependable high-current delivery to motors and actuators
- Custom battery pack projects where 50A continuous discharge is a hard requirement

⚠ Important Safety Warnings
Improper handling or misuse of this lithium-ion battery can result in FIRE, EXPLOSION, or THERMAL RUNAWAY, causing personal injury, property damage, or death. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.
- Critical Warning: Never carry loose batteries in your pocket, purse, or bag. Loose batteries can come into contact with metal objects like keys or coins, causing a short circuit, which may result in severe burns, fire, or explosion. Always store or transport batteries in a protective case or box.
- Intended Use: This battery is designed for integration into protected battery packs with a Battery Management System (BMS) or Protection Circuit Board (PCB). It is not intended for standalone use or use in devices such as e-cigarettes or vaporizers.

What is Thermal Runaway?
- A dangerous chain reaction where heat generated by a failing battery causes it to overheat further, potentially leading to fire or explosion.
- Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
- Prevention: Use a smart charger, avoid physical damage, and store batteries in a cool, dry place.
- Storage & Transport: Always store batteries in protective cases or boxes to prevent accidental contact with metal objects. Never store loose batteries in pockets, purses, bags, or near conductive materials.
- Inspection: Do not use if the PVC wrapper, terminal insulator, or casing is damaged, dented, leaking, or bulging. These are signs of internal damage or instability, and continued use could result in failure, fire, or explosion.
- Charging: Use a smart charger designed specifically for lithium-ion batteries and ensure that the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
- Prohibited Activities: Do not short circuit, modify, puncture, crush, expose to liquids, or solder directly onto the battery (spot weld only).
- Emergency Response: If a cell shows signs of thermal runaway (smoke, swelling, hissing, or heat), stop use immediately and, if it can be done safely, move it to a non-flammable surface (e.g., concrete or sand) away from combustibles. Lithium-ion cell fires are Class B fires — use an ABC/dry-chemical extinguisher, or douse with large amounts of water to cool the cell and prevent spread. Do not rely on a small spray; thorough cooling is required, and cells can reignite from residual heat, so monitor the area afterward. (Class D extinguishers are for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.
