2nd Battery

[macojoe]

i just put new battery's in yesterday, two 27m-xhd from interstate battery's. 850 cca, 1000 mca
Boat started right up after a long winter nap!!
switch #1 to first battery, #2 to 2nd battery, i also have a wire running to the cabin for all power to front, that comes off the 2nd battery, also a 1100 gal bilge pump to each battery.
Start boat on #1 battery then put on both to charge, then when fishing i stay on 2nd battery all day, so if i kill it i just switch #1 and start and go. but always on bth batterys to charge on way in.
has always worked for me with no issues! but agree to have same batterys for same charge and discharging.
my pumps go right to a battery, 1 on #1 battery and 1 on #2 battery with no fuse and one mounted a little higher then the other. this way one will work till first battery dies the the 2nd one will take over till that battery dies.no problem for a burned out fuse if none there.
I also have a 700 in the rear and a 500 that are hooked up with manual switch to pump anything i see before the auto 1100's do, they just for when boat is on the morring
