[QUOTE="Wallyc, post: 481499, member: 23693"] Best bet is keep the one in the back and run your accessories off of that. Some fish finders are more sensitive at lower battery voltage than others. I run hummingbirds and if the battery voltage is low my birds start doing weird things. Helix 9 and a 10 plus a 360 and a hub to link it all .I have no motor to charge the battery as I am electric only so I run a group 31 sla battery . Overkill ? Probably but it guarantees I don’t take more than 50 % of the battery on a 13 hour day which is my limit. Lead acid don’t like discharge below 50%. Lithium are a different animal you can use more than 50 % without hurting the battery so you should be ok for 75% discharge. It you ever upgrade your finder to bigger screen 12 amp hours won’t be enough. [/QUOTE]
