-It will be gentlest on the system to combine the batteries and allow the starter battery to come up a bit instead of immediately attempting to start.
 This will be easiest if one already has some kind of [[electrical:12v:alternator#isolators|isolator/combiner]] setup. If not, one can run jumper cables from the house bank, or physically remove the house bank and carry it to the starter battery area.

 Some standalone solar 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.
-The BIM (see above) also maintains the starter battery when house battery voltae FIXME
+[[electrical:12v:alternator#voltage-sensing_relays|dVSR isolators]] automatically connect the banks when house battery is sufficiently charged.
