6 FAQs about [How much power should I choose for the lithium battery fuse]
What fuses do you need for a lithium battery?
There are various fuses to consider, such as blade-style, ANL fuses, and standard 10x38 fuses. Blade-style fuses, common in automotive applications, aren't typically suitable for lithium battery systems. ANL fuses may also fall short in voltage specifications for these types of batteries.
How to choose a battery protection fuse?
The battery protection fuse is there to protect the main battery cable so you should choose a fuse with Ampere rating higher than the maximum possible current of your system and less than the current rating of the cable. It is NOT determined by the battery BMS continuous current rating (this is a characteristic of the BMS not your system).
Are ANL fuses a good choice for a lithium battery?
ANL fuses may also fall short in voltage specifications for these types of batteries. A better option is the standard 10x38 fuses for smaller battery systems. These come with ceramic tubes filled with auxiliary materials, providing the high interrupt current ratings necessary for lithium battery systems.
How many volts can a DC fuse run?
Most commercial DC fuses are rated for up to 32V (making them appropriate for 12V and 24V systems) whereas a 48V battery bank will require a fuse that is rated for up to 58V. This refers to the maximum fault current that the fuse is able to interrupt under test conditions.
Are Mega fuses good for a lithium battery?
MEGA fuses are perfect for loads and chargers as they come in a range of Ampere ratings from 60A to 500A, they are common and easy to source due to their use in vehicles and they are relatively cheap. They are not suitable for use as the main battery protection fuse with a LiFePO4 lithium battery however.
Which battery fuses should I use?
For quality assurance, some reliable and safe brands to consider are Blue Sea Systems and Little Fuse. In large battery banks, the fuse selection becomes even more critical. UL 248-14 certification fuses are advisable. Smaller style fuses mentioned earlier like the 10x38 fuses, may not suffice.
