well ive just purchased a 1198c for my kayak, no i know manual say 1.4A but this is no back light and prolly nothing connected.

when playing with it i was usinga 12v 7a/hr sla hooked up to a 2A sla charger and teh volts were still dropping. so its say to say caurrent draw is 2A.

i want to know what size battery or how many 12v 7a/hr batterys i need to run it for 10hrs considering i will have 0 charge going back into battery unlessless i us emy soalr pannel but i only us etaht when i use teh electric.
