Back Plate "Altoid Power Packs"
This is a very new idea I will be trying out in 2026. I've had some batteries rigged in the back plate for a long time on troops but it was just haphazard velcroed pieces with no real order to it. I came up with an idea using Altoid tins. Note: I've not trooped with this yet. I have some attachment strength, positioning, and making sure they are not visible to work out, but I love how this came out. I will only troop with it if I have the front plate with my speaker and ABS bracket mounted on the chest plate to counterbalance the weight. It's not heavy on the back, but the power bank adds just enough to it. (I weighed the pieces, and the total weight is right at 16 ounces for all 4 pieces. I got a different USB Power bank that was even closer in size to the Altoid tins and only weighs 3.8 ounces.)
First, I logged all the electronics I'm using which include: helmet fans, wireless mic, TRamp speaker, air pressure sound board in helmet, MP3 player on blaster, and sound fx/music speaker hidden in holster. I currently am using two 9 volts, two CR2032 batteries, one device charged with USB-C, and two devices charged by Micro USB. That helped me determine what I needed in my power packs. Here's what I did:
Using Altoid tins, you can simply paint these black or white or whatever you like. I decided on black since it will go up against the black skin-diving suit. And it matched the color of the USB Power Bank. I then made some logo stickers to represent what is stored in each power pack. I wanted a symbol instead words or lettering. It looked neat. Then of course slapped the imperial cog decal on there on the right side.
Each power pack stores what I need for power. You could make an internal liner in the case. But I found some folks on Etsy that make cheap 3D printed storage parts for Altoid cases. I got one the holds three 9 Volts batteries. Another one was a piece made for storing headphones - I used it for the two types of cables -Micro USB and a pigtail USB-C cable. The last case was a neat little mini tool chest that I use for brackets and screws but also for my CR-2032 batteries. Finally, I found a USB Power Bank that was as close in size to the Altoid tins as I could find. Then added the stickers to show was stored in each case.
Next was the mounting. The Altoid tins work great for using earth magnets. I found small rectangular earth magnets on Amazon. It was so strong, I decided to wrap them in 6-inch strips of white duct tape to reduce the draw power. That worked great. I used two strips of 6-inch tape around them. If I troop and find it's a little loose, I'll drop one of the tape strips that wrap around the magnet to make them stronger. Small tests around the house don't seem to be a problem so far with the two layers of tape. I'll do a test troop in full armor at some point to verify though. I also need to see how much the screws/nuts rattle in the one tin. Test walking in the house didn't make much of a sound which surprised me.
I used clear double sided Gorilla tape to mount the magnets on the interior of the black plate. Since these power packs are not too heavy, there's not a lot of weight for the magnets and Gorilla tape to hold the tins. I wanted it to be easy for someone to reach inside my back plate to easily remove the needed power pack without the tear and pull of velcro. However, I didn't want to use magnets on the USB Power Bank. I put just a little hook velcro on the back of the bank itself and then a piece of loop velcro in the back plate.

Finally, the pieces in place. It looks awesome and everything is neat, organized, and labeled. I put a "safety hold" black rubber band around each tin. I don't think they'll pop open, but I thought that would be a good safety to have on them just in case. I really hope this works in my test troop. I'll post results once I give it a whirl. I did want to share this idea though. I'd love to see how others hide and store backup power and batteries on their armor.
