Custom Electric Tank bag

O.k. So before I go ahead with this project, I wanted to run some things by the forum for input. You know, to see if there's something I didn't think about yet.

So I have a MotoCentric Moto 19 strap equipped Tank bag. I like it. I want to add 4 micro usb charging ports inside of it for my phone, 1-2 sena headsets and maybe my spare battery pack/passengers phone/unforseen accessory.

The vision is to have foam cutouts for the Sena(s), and have everything self contained so that when I park the bike, I can unsnap the 3 bag connections to the bike and disconnect one electrical connection from the PC8 to carry the bag with me. (The bag has backpack straps that clip into the bike mounting points, and I actually use this feature more than I ever thought I would.)

Additionally, I thought it would be cool to modify a wall wart with the same connector. Then I could plug the tank bag into a wall outlet to charge the stuff in the bag without unpacking it.

The connection I was thinking of using to connect the PC8 to the tank bag is this weatherpack connector below. It would be next to the buckle that holds the tank bag on by the nose of the seat. This way, I could still flip the tankbag easliy out of the way to fuel up without having to disconnect the electricity.

The wires going to and from the weatherpack connector I would organize in some way so that they are protected and as inconspicuous as possible.



The closest thing I've found, and something I really like is what RCinNC did in his post here, but I dont' want the clutter of extra wires that come with the cigarette lighter plugs or the Powerlet and BurnsMoto gear as it just takes up so much space (and is expensive, as seen in the links)

I thought two of these would be cool, and I could splice the outputs to connect two micro USB ports on the end.

I have a PC8 installed under the seat and was planning on running 4 wires to the weatherpack connector from two switched banks on the PC8.

Total cost would be around 30 bucks estimated.

Thoughts?

P.S. Some really wild ideas to increase the complexity of this device (which may be even more overkill) was to have the circuit sense when the devices are fully charged and to stop charging automatically when this happens and also maybe having a bank of indicator lights to show this. I don't know what is required to make this happen though, so it could be out of my skill level and way more work than it's worth.

If you are wanting to power your tank bag, or any luggage for that matter, take a look at Powerlet (Luggage Electrix - Powerlet Products). Quality stuff, I have been buying from them for years.

Yeah, I checked these out (as linked to in the original msg). I just don't want wires plugging into wires inside the tank bag. I'm trying to leave unnecessary components/bulk out of the bag. Plus man, are they expensive!

Thanks for taking the time to respond though guys, I really appreciate it!

here's what I did- simple and cheap.


I used this ($3.87 on amazon)...


I cut the lead in half and soldered on extra wire to extend the length. This plugs into the lead coming from the aux fuse block on the bike. That means the tank bag is only receiving power when the key is turned on.

This setup gives me 4 SAE leads inside the bag to play with.

Then I bought this ($12.99 on amazon)...


I cut off the male cigarette end and soldered on an SAE lead, which saves space inside the bag. However in doing so I cut off the fuse, so be sure that your circuit has a fuse somewhere else!

I needed more USB ports, so I added two of these.


that gives me 6 powered USB ports in a small space. If you need more, just use another unit powered by another SAE lead on the splitter.


Also... the male end I cut off doesn't go to waste. I soldered on an SAE lead to it, then combined it with this (a few $$ on amazon)...


now I can plug in the whole tank bag to AC power and everything inside the bag is powered, without removing it all! This makes it a breeze to step into a restaurant or motel and keep everything charged by plugging in.


This whole setup cost me less than $20, but some of the parts I had lying around.

Definately the closest thing I have seen to what I'm thinking. How many items do you charge at once? Do you notice a decrease in charging speed or ability to keep your tablet charging when multiple items are plugged in?

Thanks for taking the time to post!

I have a bunch of stuff charging/powered in the bag while I am riding...

1) voltmeter
2) gps
3) tablet computer
4) phone
5) gopro camera
6) gopro internal battery dual charger ( Amazon.com: Smatree® Battery(2-Pack) and Rapid Dual Charger Kit for GoPro® HD HERO3,HERO3+ camera - Includes:Smatree® high-speed USB Dual Travel Battery Charger + 2 Smatree® power High Capacity Rechargeable Li-ion Batteries + USB Cable + Fast Dual US )
7, 8, 9) gopro external battery x3
10) camera battery charger (via cigarette adaptor)
11) wifi mobile hotspot
12) bluetooth external speaker
13) spare battery/charger, which also serves as a wifi hotspot, a SD card reader, and a powered hub ( Amazon.com: [ALL In 1] EasyAcc® WiFi Wireless USB Flash Drive / SD Card Reader, Wireless USB HUB USB External HDD / SDD Reader,Portable Wi-Fi Router & Wi-Fi Repeater for Andorid / IOS / Mac OS ,Built-in 8800mah External Battery Pack for iPad 4 mini / )

All of this charging does not drop the voltage on the bike, but if I plug in the heated vest at full power then it's too much and something has to be unplugged. The voltmeter is essential to monitor the system.

btw- all your electronics sense when they are charged and stop charging automatically. No need to worry about overcharging.
