LiPo charging case

Charging case to charge up to 4 batteries at the same time.

## Power source

Three options to power the case
- Main power
- XT-60 (7 - 28V DC)
- Banana plug (7 - 28V DC)

### 24V PSU

I've put 2 server PSU's 460W each in the bottom of the case and connected them in serie.

**ATTENTION!!** you need to isolate the second PSU from the ground to prevent a short circuit!

You can also use 12v, but then you can not utilise the full potential of the chargers and the current in the wires will be greater.

### Internal battery

I did not include an internal battery because I already own some bigger LiPo batteries and I can easily plug those in. There is not a lot of space left in the case, so it would be difficult to fit it in.

### Cooling

2 fans for cooling are powered by a DC/DC converter connected to the left charger input.
The DC/DC converter is needed because the fans require 12V and the input voltage can range from 7V up to 28V.
