Lowrance ??

I am using a new power source and am wondering how long it will run my unit on a full charge.....if I run it in the garage on demo until it shuts down will that give me a close estimate of  running it OTW ...it is a DSI-5 color W/ GPS.........

Thanks in advance for the help...

The unit will draw 1.1amps per hour max.  I find it draws less in reality.  Figure out your amperage of the battery & divide by 1.1.  Your realistic useable amp hours will be about 75/80% of the listed ones on the batt.

   I have the Elite 5,    been using a 5Ah lithium that seem to hold up for 5.5 - 6 hrs before shutting down at around 11 volts.
   I wish now I'd purchased the 10ah ... 

Sounds bout right Jim.
