Some high-end home energy storage systems incorporate Aerosol Fire Extinguishing devices. These are fire suppression systems that release aerosolized particles containing potassium ions and other radicals to inhibit the combustion chain reaction. Although I have never seen these sold to general...

It appears that Xinrong has recently released a new battery case called 'XR-08' equipped with a JK BMS. Although the lack of protective devices like circuit breakers or fuses is a concern, the price is attractive. https://aliexpress.com/item/1005006827900134.html

Hello everyone, I have a question regarding the difference between 2-pole (2P) and 3-pole (3P) DC surge protective devices (SPDs) used in PV systems. As I understand it, a 2P SPD protects the positive and negative lines, while a 3P SPD protects the positive, negative, and grounding lines. My...

When installing a fuse for a DIY battery, it is common to place it as close as possible to the positive terminal of the battery cell. While installing a fuse on both the positive and negative sides can provide redundancy, typically, a single high-quality, reliable fuse installed on the positive...

According to the description on the product site of the company manufacturing this aerosol fire extinguisher, it seems to be capable of extinguishing battery fires. The mechanism of extinguishing is also explained. (However, I do not have a background in chemistry, so I do not fully understand...

The datasheet of the LF304, which has a similar capacity to the EVE MB30, states that it has 4000 cycles until its capacity degrades to 80% when charged and discharged at 0.5C. Considering this point, isn't the MB30 an upgraded cell that has a large capacity yet maintains durability similar to...

Do you have a test report for the MB30? According to EVE's datasheet, the MB31 is supposed to have a larger capacity than the MB30, but Andy from Off-Grid Garage found almost no difference in his capacity tests.
