 [Note from secessus:  AFAIK none of the DC-DC chargers allow self-jumpstarting.  If anyone knows otherwise, please point me to the documentation.  Thanks!]
+==== dual charging solar charge controllers ====
+Some charge controllers like the [[https://amzn.to/2PPTD2L|Morningstar SunSaver Duo]] can, for example,  charge the start battery with 10% of solar harvest and the house battery with 90% using different charging profiles.  As with DC-DC above, it's not self-jumpstarting but can help prevent the dead starter battery.
