You should be concerned with that size battery and the run time - the H10 draws almost 1.5 amps, I use a 12 amp SLA with just a 688DI (under 1 amp) and your will eat that smaller battery up quick..
Lowered screen brightness helps, and going to standby or powering off will give you more time.
If you use that for a sonar as well, make sure you select the proper XDCR in the sonar XDCR selection menu - or you risk damage to the unit's transmitter final output stage.
Thanks for posting the video....
