Ultimate Waterproof Solar Power

This is my fist Instructable, I have been a member for a long time and finally decided to try to create my own. Anyway lets get to it...

I wanted to build a solar charger that i could take kayaking and not have to worry about getting wet or worry about my phone. Enter the ALL IN ONE portable solar battery.

Solar pannel(s): I used two that I found in a solar light that was ran over you know reuse recycle. haha.

Batteries: I am using some old laptop batteries I scavenged from an old hp

2X Lithium Battery Charge Controller: Brown Dog Gadgets controler

USB Charger: Dual USB Charger Brown Dog Gadgets

Diodes: 1N4001 Diode 10 Pack

Switch: I salvaged a switch from the solar light with the pannels

Silicone: I used Loctite 2in1 all purpose clear silicone

Biggest thing a Waterproof Box to put it all in

Tools:

Soldering iron

Wire

wire strippers

utility knife

electrical tape

Velcro tape

I set out all of the components in the box to see how they best fit. I found that the batteries and charging components all fit in the side compartment so that I could fit anything that needed charging could be fit into the other two thirds of the box. I bundled the ten batteries into two sets of five. One charging board per set.

Solder all the batteries together in the separate bundles and then to their respective charging circuits. Now the tricky part is that the USB charger uses a 3.5v signal to charge so you have to wire the batteries in parallel. I used two diodes to separate the currents from the different cells. I cut slots in the divider for the switch and the USB charger.

So now outside it goes and it works. Both boards charge and the switch works. AWESOME! It has enough power to charge a phone and use a light at the same time. I know it has room for improvement and please feel free to leave me a comment or suggestion. This was just meant to be a easy way for waterproof solar power on the go.
