Default What do you use to field charge?(power source)

Just curious on what you guys use to power your chargers while you're out bashing say for a good part of the day? I was wondering because I've been using my car battery but we havent had any long days out bashing, but I'm worried that if we do stay out for awhile I don't want to drain my car battery and be stuck there lol. Will a bunch of RC batteries really drain that much out of a car battery over the course of maybe a few hours so that it cant start? If it is possible I was maybe thinking of getting another car battery just to use for my chargers in the field, and then when it gets low just charge that back up with my car battery charger.

I use my car battery also. A standard small car battery supplies about 40-45 amp hours. So, a 4 amp charge rate for your RCs should theoretically suck it dry in about 10 hours or so. If you're real concerned with killing your battery and stranding yourself, just start the car once an hour and let it idle for a few minutes. If your battery is in good condition the alternator will replenish it on the drive home. Otherwise, you can hook up a charger to your car when you get home just to be sure.

Jeep's battery. Unless there's an AC outlet somewhere, then ThunderbirdJunkie uses his super awesome power supply.

i don't have a DC adapter on my charger but i was thinking about buying an AC power inverter that plugs into the cigarette lighter, is that going to drain it at about the same rate?

i have a spare car battery that i bring with me. i keep it charged at home with a craftsman 12v charger.
if that runs low while out in the field then i'll use my car's battery.

Thats exactly what I was thinking of doing, good to know someone else does it too. I guess I'll start looking around for a cheap car battery.

I have one of those emergency car jumpers I bring with me to the field. I don't use it for charging (only like 9Ah), I just use it to jump my little car if my battery dies (it has a larger battery than it needs).

Be careful that the ripple current doesn't blow your charger up[&:]

I thought maybe he was referring to the power inverter.

Is ripple current becoming an RCU meme? [&:]

I use my car battery. Never been stranded, and I've charged packs back to back for hours. My biggest problem is that I have a GM with the side post battery, but not a model originally designed for it. So the terminals are jammed right up against the front of the car, and I have to use extreme caution when connecting anything.

But yeah, given the capacities of a decent car battery and a healthy charging system, you're in greater danger of shorting the battery when connecting it than running it dry in a typical afternoon bash session. Heck, if you're like me you'll probably break all your cars and go home with half your packs fully charged anyway.

I got a nice little 10 amp sealed battery from Ace Hardware for about $30.  Its plenty powerful, and is lighter then a car battery.

Sears makes a rechargeable power inverter.  You end up with two plugs at 12V and two plugs at 110V.  Mine comes with a light, a air pump and a charger for USB.  I think they are around $100.  Cool set up with the inverter.  I've had guys at the field use it to run their covering irons.  I suppose you could even perk your coffee while you're waiting for a battery to charge if you want.  I've never ran out of power on a one-day use.  An over-night charge puts it back to 100%.

dont buy a cheap car battery,,they dont like being discharged very many times. buy a deep cycle battery made for trolling motors. do buy a cheap pair of jumper cables,,hook them up and recharge the batt from your car.

There is another way if you have 110V at the field, which we do. You can take a PC power supply and hook it up to a field charger system HOWEVER....you need to add a ressistor to the power supply board or you will fry it. I know there are procedures somewhere on the web on how to build it...and maybe even here. I used to have one, but sold it...now wish I hadn't.

I plug my charger into my cigarette lighter with a little adapter thing I made... seems to work fine.

Ripple current... I haven't heard that term in a long time...
