Specific Batteries for Livescope and 93 echomap

Some of yall that have been using the livescope and echomap 93 please post which SPECIFIC battery you are using.
I have been recommended anything from a lithium to group 31 deep cycle to group 27 regular to 2 x 12v home alarm batteries. I want one that will last for about 8 hours per day at the most.
Thanks in advance for the help.
Also if anyone is using an inline switch please post a part number and location to buy.

Some of us are not real smart when it comes to electrical

Thanks

As I understand it ... the LS system draws 4amps/hour ... so you'd want a battery that had at least a 50ah rating, I would think. Where you can put the battery & the weight and size of it may be a deciding factor. :twocents
