I recently tried to set up a dual headlight system on my bike and in the process I ended up burning out my battery box because apparently the two USB ports shared the 2 amp limit rather than 2 amps per port.

Basically does anyone know where I can find a 4 X 18650 battery box with two USB ports that have hardened independent power circuits of at least 2.5 amps per port or a total of 5 amps??

I like being able to change out the batteries which lets me double my run times on the trails so the battery compartment needs to be something i can open with my hands without needing a screw driver.

also of note I use Protected Panasonic NCR18650's which are slightly longer than some other 18650's so It needs to have a spring type battery connection instead of a tight fitting one.

At this point i have been unable to find anything near the specs i want after several hours of searching. Apparently high draw USB devices are rather rare.

Doing some further testing the average draw per light is around 1.9 amp so dual usb ports of 2.1 amp
which is more standard would suffice
