Poor mans dual battery

[specialk]

I have read how to make a 2nd dual battery system on the site, but having zero confidence in my abilities not to get electrocuted or start a boat fire, I would like to have the benefits of a back up battery without the need for an electral engineering degree. I only have a starting battery.

I have a stock radio and speakers which we rarely use, other than a recently installed heater, i really do not use much energy.

Could I simply buy another marine battery, put it in battery box, keep it there, if I do drain my other battery, take some jumper cables connect it to the other battery and start the boat. I usually put the battery on trickle charge once a month anyway, so making sure it stays charged would not be an issue.

Thanks for the input.

Yes

Yes but why go that far???

Example: Sears Jumper Battery

A BIG X2 on the jump box. More user friendly then a 2nd battery used just for jump starting. When the jump box needs recharged, just plug it in to the house.

A 2nd battery is REAL simple. There are probably .5 dozen threads and diagrams floating around here and always someone to help with ???'s

Especially if you just install a switch.

Theres is a guy on WW who works for a company that has an ACR that is supposed to work like the Blue Sea but he sells for a little more then $50, that's not much more then a Perko. Its on my list of things to look into!
