For powering the radio from batteries look for an "automatic buck-boost" regulator. This type will maintain your desired output V as the battery runs down. A "step down" regulator will only work if the battery voltage is higher than the desired output V.
For charging Li-ion packs look for a "BMS - Battery Management System" rated for your pack's size. These these handle all the over- under situations, control charging and maintain a balance between the individual cells.
I'm planning on a 3 cell pack, giving 11 to 12 volts. I can recharge them from the shack 13.8V supply or charge directly from a solar cell.
