All ActivityMost RecentMost LikesSolutionsRe: BATTERIESIt looks like I will be going with an RV CONVERTER. Have checked out a few. Powermaxx55 amp, Progressive Dynamics 45 amp, GoPower 45 amp and WFCO65 amp. What is the best brand name out of these choices? I am dumb. The converter will be using 120 volt electricity from the 2000 watt gas Yamaha inverter/generator, and converting it to DC power, boost the amps, and charge battery quicker right? The converters are smart so they have a four stage charge? these four stages are automatic? I just plug in and play? (short of adding liquid to the battery now and then)?Re: BATTERIES Tom_M wrote: I have a Stanley 40 amp charger and it will not start a charge if the battery voltage is too low. I have to use a "Dumb" charger to get the voltage above the threshold and then I can use the Stanley. A 40 or 50 amp charger is not going to be cheap. You may want to consider buying an RV converter/charger. Would I need a 40 amp charger? Times listed above are for full discharge, that should never happen.Re: BATTERIES Ductape wrote: How long do you stay, and how long between stays? I do the same thing with a small solar charger, but we are gone more than we are in the cabin. Will be staying weekends mostly. Maybe weeks in summer. Thought about sat to keep topped offRe: BATTERIES enblethen wrote: Have you checked to see if the charger fan comes on when connected to battery before you plug into 120 volt receptacle? Verify polarity connections on charger to battery. Red clip should be positive. I have a couple Schumacher chargers and both work very well. No fan. I changed leads to reverse order on purpose and lights still never came on. The leads are bare metal and the battery terminals are cleanBATTERIESThis topic has been moved to another forum. You can read it here: 28330288BATTERIESI recently have purchased an off grid hunting camp. I have purchased two GC2 batteries from Sam's club, each 6 volts and 215 amp hour. I will be connecting the two together in series (A positive to B negative) (B positive to load/charge and A negative to load/charge) I bought a crappie schmacher "smart" charger, connected it to the batteries, it wont do anything. Connected it to a couple of other batteries still would not work (lawn mower, motorcycle). I will be sending it back. With the batteries connected as stated above, I should be charging in 12 volt mode correct? What is a good cheap quick smart or 3 stage battery charger? I will be running the battery charger on gas Yamaha 2000 watt inverter. I don't want to run the inverter all day. I know to figure out how long to recharge is battery amps / by charger rated amps + 10% In my case, 215/30=7.2 + .72= 7.92 (8 hours) that's a long time. Maybe need a 40amp (about 6 hours to recharge)or 50amp (about 5 hours to recharge) Those hours are from complete dead state which "should" never occur. From the batteries, I will only be running a few cfl lights, maybe a fan, and maybe a radio for 5-6 hours at night. then recharging during the day. Any help would be greatly appreciated.Re: ?? 6 or 12 VOLT BATTERY ??Can I charge two 6 volt batteries connected in series with a 12 volt charger?Re: ?? 6 or 12 VOLT BATTERY ??I have an old hood vent from an oven that I got from someone. Not going to actually plug the fan and light in but was thinking of using this overtop of the batteries and venting to the outside.Re: ?? 6 or 12 VOLT BATTERY ??Where can you but distilled water? The 6 volt Golf Car batteries would need to be in a vented area when charging and discharging?Re: ?? 6 or 12 VOLT BATTERY ??I am pretty sure I am going with 2 Duracell 6 volt 215 amp hour batteries from Sam's Club connected in series to make 1 12 volt at 215 amp hour. Going with the Energizer 1500C/3000S watt inverter (I like this one because it has the modified sine wave and a digital read out on the top of the unit so I can mount it to the wall and be able to read it). Also thinking of going with the Schumacher 15/8/3 Amp Ship N Shore Battery Charger (3 stage charger 2/10/15amp). The specs say it is for 12 volt batteries. Can I use this charger to charge the 2 6v batteries in series (technically making it a 12 volt battery)?
