Battery Ideas for New Dragonfly 6

[Lipripper92592]

Rule of thumb for battery discharge

Lead Acid 60%
Lithium based 80%

So a ten amp hour battery with lithium chemistry will give you about 8amp hours before you start to "hurt' the battery. This is about the cheapest "power" I have found so far.

Wanting to be able to utilize my Dragonfly 6 to its fullest capacity, I piggy-backed Lipripper and ordered the Tenergy Li-Ion 18650 11.1V 17.6Ah Rechargeable Battery Pack w/ PCB Protection (DGR-A). I also ordered the Tenergy TLP-2000 Smart Charger for Li-Ion/LiPo Battery Packs: 3.7V - 14.8V.

The operations manual calls for a 3 amp in-line fuse. It also calls for a 5 amp thermal breaker. Is it either/or? Thanks again.

Just a single fuse will do just fine. My fishfinder isn't fused at all, I just run mine strait to the battery. The possibility of a short is pretty slim to none, if you have wired it correctly.

Make sure that you don't get the battery wet, even if you roll it.

I need to extend the power cord, would any wire work or does it have to be a certain size. Got confused looking at all the different ones at hardware store...

And if I run a fuse does it matter which wire to connect to?

Try to use marine grade wiring if possible. Fuse the positive side if you are going to fuse.
