Fuses between Aux battery and power panel?

[bishbashbosh]

When attaching this Baintech Power Panel (http://www.baintech.com.au/power-panels/baintech-new-universal-panel-ciga-engel-usb) to my aux battery (Full River Deep Cycle 105) will i need to protect it with a fuse or does the baintech panel have everything in it thats needed to protect and i'm ok to just plug my electrical items up to it?

This is how it goes - My Aux Battery is in the cargo area with my Ctek


Starter Battery

(8AWG Cable + 40AMP Auto Reset CB)
+
Ctek D250S Dual

(8AWG Cable + 40AMP Auto Reset CB)

Aux Battery

Baintech Power Panel



Off this i'll run my 45ltr engel, and small led light in the back as needed for seeing what i'm looking for, and charging up iPhone, speakers, iPod and laptop as needed.

The panel has its own fuse, but I would have an inline fuse of some type as close to the battery as possible to protect against the feed wires earthing out or shorting. It needs to be larger than the fuse in the panel, but not larger than the capacity of wire that you are runing from the battery to the panel.

Thanks 4bye4!

The inbuilt fuse is rated at 15AMP but the cable they provide does not state 'capacity' so just sent them a message asking.. will report back..

Good idea, not much point in a 15 amp fuse if the cable is only 10 amp. Probably a 20 or 25 amp cable if they are running a 15amp fuse. You would then have a say 20 amp fuse for protection in case the cable wears through or gets cut at sometime. Yea I know that will never happen but if there is ever a major incident (crash) you will probably have enough issues to worry about without a battery fire as well.

just got a response - "the supplied wire cable is 8 mm in diameter and able to handle 16 amps max."

As 4bye4 said, 20 Amp fuse will be fine mate.

The cable is 8mm automotive cable so 16 amp max is the continuous useage rating.
The surge rating will be a fair bit higher.
You can use 15 amp at the battery if you like but you want the "Baintech" 15 amp fuse to go if there is an equipment fault on the sockets.
If the Battery feed is 15 amp as well then there is no point in having the "Baintech" fuse IE you have the same overload protection in two different places.

i won't add an inline fuse then in this part of the system and just keep the baintech fuse in its place.
