I scored (2) deep cycle batteries, pretty good sized ones...but..they are 8 volt batteries. If I hook them in series..I get 16.75 volts when charged with a decent "deep cycle/gell cell" charger They do indeed hold a charge for a good long time. I charged them 1.5 months ago..and tested them Sunday..and they still had 16.25 volts on them. Is 16.5 volts "too high" for most 12vt dc devices like Marine radios, fish finders, GPS devices, CB radios, am/fm/cd players and the like? I had planned on putting them in one of the sailboats, there is enough weight there for some decent fore end weight distribution. Probably 75 lbs or so..maybe 90 lbs. If the voltage is too high..what cheap and easy method is there to drop the voltage down to 13.5/12vts to run my various electronic devices? Besides a big as resistor....? I will primarily be using them for lighting..most of the boat(s) are wired for 12vt incandescent bulbs, but will be changing them if possible, to LED bulbs/lights (port/starboard/mast head/stern/cabin etc), but will indeed need the batteries to run my fish finders, GPS system and so on. I also have (6) solar panels..which put out 6+ vlts each...and had planned on putting a pair of them on the stern rail of the boats..giving me 12 volts to the ($12.95) MPPT charger/solar controller. I figure Id have to use (3) of them to get me to 18+ volts in order to charge that pair of 16vt batteries..and thats way too much real estate taken up..so will be using them around the homestead on an array. Ive not found dick on the net about 8volt batteries..but they are plainly marked as such. I figure they may ..may have been intended for a 24 volt system ..and there should be three in series. Any insight, information would be greatly appreciated. Thanks! Gunner -- "Virtually all members of [radical] groups sincerely believe that they are fighting the Establishment. In reality they are an indespensible ally of the Establishment in fastening Socialism on all of us. The naive radicals think that under Socialism the "people" will run everything. Actually, it will be a clique of Insiders in total control, consolidating and controlling all wealth. That is why these schoolboy Lenins and teenage Trotskys are allowed to roam free and are practically never arrested or prosecuted. They are protected. If the Establishment wanted the revolutionaries stopped, how long do you think they would be tolerated? --- This email is free from viruses and malware because avast!
