I recently installed some new electronics on my Triton 189 TRX and all are wired to my cranking battery. I have Helix 7 (.9 amps), x 2 Helix 10 (2.4 amp each), Garmin Echo Map Ultra 126 (3.3 amp) and Livescope System (1.75 amp). I also have a one 10 foot power pole, and the typical other systems that require electricity such as live well, lights, and pumps. Obviously, my current battery (Interstate Marine Cranking 27M-XHD) isn't cutting it and drains pretty fast. I can't get a full day of fishing out of it. What should I do? Is there a large battery that I could go with to meet my needs? Do I need a second battery to only run the electronics? Do I get a second battery and a switch where I could go between the two if one dies? Thanks in advance for the input.
