### ⭐⭐⭐⭐⭐ 







  
  
    Compact and simple
  

*by G***A on Reviewed in the United States on January 6, 2020*

I am using this on an 8-battery solar bank with each 2-battery series fused on the load side. This provides short circuit/overload protection at each module as close to the battery as possible. Having the fuse block on the battery also makes for a nice heat sink. The block and fuse are very compact and easy to install. Remember to account for a fused connection in your overall wire load/temp/size calculations - there are plenty of online calculators out there to make this calculation for you.

### ⭐⭐⭐⭐⭐ 







  
  
    Although Pricey--It is the Better Option
  

*by I***E on Reviewed in the United States on January 10, 2020*

Rather than buy a $10 fuse/fuse holder and have to cut the battery cable to splice the fuse holder in, this great alternative is far easier to install on the battery itself and allows you to maintain the integrity of your cables uncut--providing more cable strength, current pass through and options for passing cables through bulkheads, etc.

    Fuses are like a condom you be glade you used them sooner or later.
  

*by J***  on Reviewed in the United States on April 19, 2021*

If you have batteries of any kind you need to put these on them to help protect your investment. If something were to short out this could prevents wire damage and fire if you get the right size fuses to go with it.  I have 6 deep cycle i have these on that power up my solar system. If anything does happen they will save my system and house. I only put 75 amp on each one. 75 x 6 = 450 amps thats a lot of go go juice that can do some serious damage. So don't think you need more then you should. Under size you fuses if you blow one, find out why then upsize. Or just design you system to match you needs. I see campers using 30 amp fuses in a 5 amp radio. Really?
