Humminbird lithium update

[Phoenix Jim]

This was an email powerhouse lithium got from humminbird. What they put in the manual and what they say to customers can be different. So glad because my clarity is really dialed in:

Thank you for contacting Humminbird. We appreciate your
support of our products.
The operating range for the voltage for the Mega Live is
between 12 and 20 volts. A 16 volt battery is safe to use so
long as the power is wired correctly and a 2 amp fuse is
installed.
If we can assist you further on this subject or any other
Humminbird related questions please feel free to email us
again.
Good Boating and Fishing!

Jim, it seems that your Humminbird equipment is going to be safe running on 16 volts. My question is whether or not your boat electrical system is going to be safe running the way you said you were installing the battery. I saw in your install video that you were going to parallel the 16 volt battery to your 12 volt starting battery. It seems to me that the 16 volt battery will hold the boat electrical system at 16 volts, at least until it discharges below that level. And the charging system on the motor will only charge at around a 14.5 volt level, which will not be enough to charge a 16 volt battery. In the beginning of this discussion, I assumed you had the 16 volt battery as a stand alone, with its own dedicated charger. Just my thoughts. Gary.
