Setting up a Renogy DCC30S or DCC50S with a Roamer LiFePO4 lithium battery
The Renogy DCC30/50S is a combined Solar (MPPT) and DC-DC charger. The unit has a combined 30/50A charge capacity, although this is split evenly between the two charge sources if both are active.
The solar input is also limited to 25V/50V depending on production date, so careful solar panel choice and connection is necessary.

For this guide, you will need:
Renogy DCC30/50S
Renogy BT-2 Bluetooth Dongle
