Remember that in a DC power system like you have, fuses prevent electrical fires by protecting WIRES, not the devices connected by the wires.This is not to say that blowing a fuse never prevents damage to an attached device, but that the "correct" way to think about circuit protection is to examine the circuit topology and identify faults which could result in a

6 FAQs about [Lead-acid batteries have no protection circuit]
What causes a lead acid battery short circuit?
The following mainly analyzes the lead-acid battery short circuit caused by excessive charging current, charging voltage of a single battery exceeds 2.4V, internal short-circuit or partial discharge, excessive temperature rise and valve control failure, and summarizes the treatment methods of lead acid battery short circuit as follows:
Should a lead acid battery be fused?
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
How low should a lead acid battery be at rest?
A lead acid battery should never be below 11.80 volt at rest. ↩ 'bad' battery protection solutions will just start to oscillate as the battery voltage recovers (above the cut-off threshold) when the load is removed. I bought a cheap 20 Euro unit and it was effectively useless because of this problem. ↩
How do you protect a lead-acid battery?
The circuit of Figure 1 protects a lead-acid battery by disconnecting its load in the presence of excessive current (more than 5A), or a low terminal voltage indicating excessive discharge (< 10.5V). The battery and load are connected by a 0.025Ω current-sense resistor (R1) and p-channel power MOSFET (T1).
When should a lead acid battery be charged?
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
What voltage should a lead acid battery be at 0%?
Be sure you look at a table that correlates resting voltage against SoC and not the voltage under load. If you see a table with 10.8 volts at 0%, you are looking at a table for under load voltages. A battery at 10.5 - 10.8 volts at rest is probably damaged. A lead acid battery should never be below 11.80 volt at rest. ↩
