These EVE 25P 18650 batteries are grade A cells and not rebranded. They perform as well as the very popular Samsung 25R. This makes these cells ideal for battery packs due to their consistent SoC (State Of Charge) voltage, internal resistance, capacity and performance.
Established in 2001, EVE Energy Co., Ltd. (hereinafter referred to as EVE) was first listed on Shenzhen GEM in 2009. After 23 years of rapid development, EVE is now a global lithium battery company which possesses core technologies and solutions for consumer, power, IoT and renewable applications.
They are one of the leaders in battery technology and are constantly at the forefront of research and development.
With a maximum continuous discharge current of 20A, this makes these cells ideal for battery pack builders.

External charger is recommended for optimal balanced charging, speed and safety.
Batteries will only have test charge. Ensure batteries are fully charged to reach full capacity. Failure to do so may lead to long term cell issues.
This cell is unprotected and intended for use in protected battery packs. In order to operate safely it must have additional protection in the form of a protection circuit board or a Battery Management System.
Usage & Charging
!!!!! IMPORTANT!!!!! These are immensely powerful batteries, and extreme care should be taken using them. Only use with brand name, quality chargers and equipment! Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these (or any other Lithium Ion) batteries with proper Lithium-Ion chargers and equipment. Lithium-Ion batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge.
Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!
- Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
- Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
- Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
- Do not short circuit your batteries! NEVER short circuit a 18650 (or more other) batteries! Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
- Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
- Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
