battery replacement for Olympus / OM System BLS-50
Ready to work under heavy load
When shooting in 4K and transmitting video, cameras can consume up to five times more energy than in single-shot mode with live view. These demanding conditions are a routine part of a photographer’s work and represent the natural environment for Mathorn batteries.
Charge Mathorn batteries quickly, safely, and conveniently using the USB-C port
By choosing Mathorn batteries, you eliminate the dependence on a dedicated charger or access to a power outlet. The built-in charging module with a USB-C port allows you to connect the battery directly to a universal USB charger or power bank, making the charging process both efficient and safe for the cells. We recommend using the USB-C port for charging instead of basic chargers that may lack the necessary protective features.
Great for occasional photography
The integrated low-power electronics, along with modern prismatic lithium-ion cells, ensure that the Mathorn battery has a self-discharge rate of just 0.5% of its total capacity per month. This makes it an excellent choice not only for everyday use but also for occasional shooting.
Power reserve for your future cameras
The exceptional efficiency of Mathorn batteries results from our proprietary measurement procedures. We have developed power profiles for the latest and most demanding cameras on the market, selecting components that guarantee optimal performance. This approach ensures that once you purchase a Mathorn battery, it will continue to serve you well even if you upgrade to a newer camera model.
Distinctly reduced heating during operation
Thanks to advanced high-current lithium-ion cells, Mathorn batteries can handle power consumption up to twice that of conventional cells. This increased efficiency results in less heat generation, leading to reduced camera overheating and extended battery life.
Laboratory-proven quality
We are committed to ensuring that the technical specifications of our batteries accurately reflect their performance. Each product undergoes thorough testing using state-of-the-art photographic and laboratory equipment. This guarantees that our batteries meet both our rigorous standards and your expectations, with declared capacities matching their actual performance, even under heavy load.
Best compatibility with your camera
Mathorn batteries are designed in accordance with the specifications of the latest camera models. Before launching any products, we rigorously test their compatibility from mechanical, electronic, and software perspectives to ensure optimal performance and seamless operation.
Guarantee and safety
The lifespan of a battery is influenced by various usage scenarios, which are not always optimal. To address this, every Mathorn battery is equipped with comprehensive active and passive safety features. These safeguards reduce the risk of damage and prolong the battery’s trouble-free operation. For added peace of mind, we offer a 3-year warranty on every battery!
Long service life
The lithium-ion technology and safety systems used in Mathorn batteries enable them to endure up to 500 full charge and discharge cycles. The absence of a memory effect and the high capacity encourage frequent partial recharging, significantly extending the overall service life of the battery.
