Mathorn battery MB-242 2400mAh Ultimate USB-C replacement for BLX-1

Mathorn MB-242 Ultimate

The most efficient replacement for the BLX-1 battery on the market with USB-C charging function.

Longer runtime than the manufacturer's battery

Mathorn Ultimate batteries are equipped with specially designed high-current cells with a capacity of 2400mAh. The increased capacity makes them not only more efficient than any other alternatives on the market (over 15% longer runtime than standard Mathorn batteries), but also surpasses dedicated manufacturer's batteries (almost 10% longer runtime).

Ready for heavy-duty use

Mathorn and Mathorn Ultimate batteries are designed for heavy-duty use, making them excellent even for filming in 8K resolution. The Ultimate line takes the declared performance to a higher level, extending camera runtime by up to 21 minutes compared to regular replacements.

Charge Mathorn batteries quickly, safely, and conveniently using the USB-C port

When choosing Mathorn batteries, you are no longer dependent on having a dedicated charger or access to the power grid. A built-in charging module with a USB-C port is designed to connect the battery directly to a universal USB charger or power bank. This makes the charging process the most efficient and safest for the cells. It is also advisable to consider charging the battery via the USB-C port instead of using the simplest chargers which are not equipped with appropriate protections.

Great for occasional photography

The built-in low-power electronics and the modern chemical formula of NCR cells set Mathorn battery self-discharge rate at 0.5% of total capacity per month1, which makes it an excellent choice, not only for everyday use but also for occasional shooting.

Power reserve for your future cameras

The unique efficiency of the Mathorn battery is the result of our original measurement procedure. We created power profiles of the latest and most demanding cameras available on the market and then selected components that ensure adequate performance. Thanks to this approach, once purchased, the battery will remain with you even when you replace the camera with a newer one. 

Distinctly reduced heating during operation

Thanks to modern high-current lithium-ion cells, Mathorn batteries can withstand up to 2 times higher power consumption than conventional cells. Higher efficiency means less battery heat, resulting in reduced camera heating and longer battery life. 

Laboratory-proven quality

We want the technical specification of our batteries to coincide with reality, which is why we test each product using modern photographic as well as laboratory equipment. Thanks to that, we can be sure that the product will meet our rigorous standards, as well as your expectation. The declared capacity of our batteries coincides with their effective value (even under heavy load).

Full compatibility with your camera

Mathorn batteries are designed following the specifications of the latest camera models. Before launching the products, we test their compatibility in terms of mechanical, electronic, and software issues to ensure smooth operation and the best performance possible. Compatible camera models: OM-1

Guarantee and safety

The lifetime of the battery is associated with different scenarios of its use, not always optimal. That is why we have equipped each Mathorn battery with all currently used active and passive protections. They reduce the risk of damage and extend the period of trouble-free operation. To ensure user peace of mind, we provide a 3-year warranty on every battery!

Long service life

The NCR lithium-ion technology and safety systems used in Mathorn batteries allow the device to withstand up to 500 cycles of full charge and full discharge. No memory effect and large capacity encourages more frequent, partial recharging of the battery, which significantly extends its service life.

The most important features:
