FAQs about Where is the battery pack fuse connected
Where should a fuse be connected to a battery?
Connect 2 fuses, one at the positive and one at the negative battery terminals.

Should a fuse be connected to a negative battery terminal?
Connect two fuses, one at the positive and one at the negative battery terminals. Also, during my research, I came across a post that advised to connect a fuse at the positive terminal since it would protect both circuit and the battery, but if the fuse is connected to the negative battery terminal, then it only protects the battery. Is this true?
What happens if a battery fuse blows?
Since the negative terminal of the battery is normally considered "Ground" or "Zero Volts", a fuse in the negative lead would leave the rest of the circuit "hot" - usually Not a Good Thing. Recommended practice is to place the fuse near the positive terminal of the battery, so the whole circuit will be dead if the fuse blows.
How do fuses work on a car?
Figure 1c is the way most vehicles are wired with a negative connection to the chassis. The fuses are placed in the positive lines from the battery and close to the battery. If a fault occurs on the line between the fuse and the load the fuse blows and current flow stops.

Self-discharge of lithium battery pack
This self-discharge ⇱ is built-in: tiny internal reactions (chemical side‐reactions and micro-shorts) bleed off energy over time. A moderate rate (around 1–3% per month for good Li-ion cells) is normal. But excessive self-discharge wastes capacity, accelerates aging and can even pose. Lithium battery self-discharge refers to the natural reduction in a battery's charge over time while in an open-circuit state (i., not connected to a load or charger). In other words, the battery loses the energy stored in it by itself due to its internal behaviour even when the connected application is not. This natural process, called self-discharge, affects battery life and performance. Lithium batteries power everything from smartphones to electric vehicles.
