With lead acid batteries, the potential fault current may be several hundred Amps. So you should select a fuse with an interrupt rating of at least 1000 Amps. If the wire has to run a long way, you may need to use heavier wire to avoid excessive voltage drop under maximum load. That is fine. You can still use the 100 A fuse with larger wire.
According to the ABYC, you should add a properly sized fuse to your battery charger output lead "in accordance with ABYC recommendations". The survey report for your boat also mentions this requirement.
To manufacture a lead acid battery, first, apply the negative paste composition to a grid and dry and cure the paste to form a negative battery plate. Then, assemble a positive battery plate and the negative battery plate to form a green battery. Lastly, convert the tribasic lead sulfate to sponge lead by electrochemical reduction in step 24.
Fuses are sized for the load Right now the top battery choice is a PowerUrUs 12V 200 Ah battery, two batteries in parallel. Four 100Ah batteries in parallel with 100A BMSs is a possibility. I was thinking of suitably sized MBRF fuses in each battery terminal with a switch for each battery.
That means 2 awg with a 200 amp fuse minimum for the battery circuits. 1/0 awg with a 250 amp fuse would be better. Since you will have pure dc loads via the legacy dc distribution panel its typical to run 6 awg wire to the panel and use a 100 amp fuse. Check the dc panel to ensure that it is rated for 100 amps.
If each battery is individually fused with adequate breaking capacity and depending on the topology you don't need the class-t for the aggregate position. Makes things a bit simpler. Lets talk about topology. Fusing and wiring decisions are dependent on topology.
Yes, a 36V sealed lead acid battery needs a fuse for protection. Place the fuse close to the battery, matching the amp rating. Use an inline auto fuse holder with a 30-40 A …
I will likely use a Lynx Power-In with the modifications to add fuses instead of distribution blocks and separate fuse blocks except at the batteries where I''ll use the MRBF. …
I put an ANL fuse in each battery lead individually, as close to the positive battery terminal as possible. The reasoning was that it will blow if a short develops between …
