HOW TO: Battery terminal fuse blocks

[John E Davies]

The factory wiring leaves those great big cables unprotected between the batteries and the main fuse. This mod adds individual fuses at each battery positive post. The fuse size you pick should depend on the battery maximum current rating. For my Battle Born lithium 100 amp hour batteries, 175 to 200 amps is appropriate. 

NOTE these may not work on the factory wiring, a lot depends on how much room is available and if the cables have enough length and if they will fit properly. You might need to replace a cable end with a different shaped one. This thread is a FYI for folks who might want to modify the factory setup. 

 

 

 

 

Search for discounted prices, these Blue Sea parts can often be found at marine suppliers for way les than Amazon Prime and they often include low or free shipping too. The blocks and fuses are sold SEPARATELY. Be sure to buy a couple of extra fuses for your spares kit.
