What the thread found

• A second battery plate connects to the sled base via a 3-pin LEMO connector and allows two batteries to be wired in parallel or series mode using a switch
• The official second battery plate includes a 12V/24V mode switch that controls whether batteries are connected in parallel or series
• A rectifier diode must be included in a custom second battery plate to prevent back-charging between batteries of different charge levels, which can cause batteries to lock out
• Without a rectifier diode, charging indicators on batteries may light up incorrectly when multiple batteries are mounted together

Depends on

• The exact LEMO pin-out configuration needed for a DIY plate is not detailed in this discussion
• The specific rectifier diode specifications are not provided
• Experience with the official plate lacking a diode appears to be from one user's specific example
