New arrival. 6 Ah LiFePO4 battery and a pretty nifty charger. Soldering the appropriate wires and terminals will be my task for tomorrow. Soon this will be powering my Yaesu FT-817nd when out and about.
@do5dos If this is one of the batteries from Eremit, I simply charge mine by connecting it to my 13,8V power supply in place of the radio.
