+LiTime makes [[https://amzn.to/3xHGjq5|a 40A DC-DC/ MPPT combo]] that looks identical to the Redodo below. Specs appear to be the same:
+  * Pv input 13.0v - 26v, max 600w
+  * Alternator Input Voltage 11.3-24VDC, max 600w
+  * Smart Alternator Input Voltage 12-24VDC , max 600w
+=== solar+alternator behavior ===
+According to the Amazon listing:
+> The DC-DC charger will choose the DC input automatically rather than charging the service battery with both the solar and DC inputs
+=== starter battery maintenance behavior ===
+> When the starting battery voltage is between 3-12V and the living battery voltage is greater than 12.5V, press and hold "REVERSE CHARGE" for 3 seconds to start reverse charging. It is recommended to start the battery when the voltage is greater than 13V and exit reverse charging when the charging current is less than 10A or the voltage of the domestic battery is less than 11V.
