Re: [Electric Boats] Watch those amps!

The wires I was attaching were not for accessories but, part of a helm mounted battery voltage monitoring display I built. These are wires are fused at the battery terminal end. I agree I also like gloves and insulated tool handles for working on the batteries.

Mike,

It’s not recommended to “TAP” or run wires from the batteries. You’re better off running a terminal strip for “accessories” off the batteries (both + and -) to a safe location near by with an in-line fuse. I recently was asked to look at a dock buddies wiring and backed away from a bank of bats that had each circuit wired directly to the batteries. All told over 20 wires off the terminals of the batteries with individual fuses to only half of them.  With a 144V system I like rubber gloves and insulated tools. :o)

Well, while I was adding some terminals for a new helm instrumentation project one if the battery interconnect cable  lugs touched the post of the battery next to it for under a second. Thought this group would like to see the result:

Not great harm but, it certainly got my attention. Just a reminder to be careful around those batteries.
