Introduction
The battery system is 24V, but split into 2x11.1V Lip batteries.
Each battery has a charger and a charge control board as shown in the schematic below.
Another board combines the two batteries and has a number of XT60 plugs for power distribution as shown below.
Charger board
Battery charge board: The battery is connected (with an XT60) at top-center called 'BAT' with the balancing cable at the pins just below. The charger is connected to the left (again XT60 and balance plug), The charge is disconnected using a relay, when not in use. The relay is activated with a small 6V supply from 230V mains (RELAY_6V). The battery meter is connected when power is on using Q3 and Q1. The AD3-CHARGE (lower-right) is for the u-processor to detect that we are charging.
