i have a field charger that i like to use, but it draws to much juice from my field box so i am wiring it to a cig. light adapter.
where can i find a cheap...powersupply i can have in my dorm so i can quick charge stuff in the room instead of out in a car?
something like this ? http://shop3.outpost.com/product/1927119
I've lost the link to the post I had found about this. I'll keep trying to find it.
Don't jump and buy that one from Fry's, yet. I remeber in the post I saw something about making sure the pc power supply you used would put out 10 amps. The link you posted showed only 4 amp output. I don't think you'd be happy with thye results.
The PC power supplies are probably the cheapest route but another way to go is to get one of the good high ouput supplies like ham radio operators use to power their rigs. Astron is one brand name. They make supplies ranging in capacity from 4 amps on up to at least 60 amps. I don't know how the cost compares to some of the other stuff out there but I do know that they are reliable and built solid as a rock. I guess I'm lucky to have my Astron 35 amp supply sitting here under the desk. I use it to power my ham rig as well as to charge batteries with my Triton charger. I can't imagine ever needing more amperage than that for RC applications.
Oh yeah, read the specs on any supply very carefully. A lot will be rated in peak amperage and the continuous duty output will be a bit lower. My supply will allow 35 amps to be drawn peak but it's more like 25 amps continuous.
oh shit fellas..
i cant build one of those..
im just a college student..and not an electrical engineering major either..
anyone want to build one for me
ill even try to find a power supply for you to hack up lol?
or should i just get one prebuilt..
what should the amp rating be at least 10 or what..
because the max charge rate is 2.5 how come a power supply rated at the same amps..how come it wouldnt be good enough ?\
The post I saw at some other site was definitely a couple years old, hence I think it was targeted towards charging NiCad on NiMh batteries. If I'm half as smart as I think I am, you push a lot more amps into those old packs as opposed to LiPolys. Probably why they called for at least 10 amps from the power supply...
Of course, if you have too much to begin with you won't be left wanting
If you can get your hands on an old "big box" type computer AT power supply you wont need anything else except a connector. call around to some computer stores and ask for old used power supply's, otherwise what you had picked in the first post works great. I have one very similar
I looked around and I happen to have an older but new JDR AT style computer PS. (Im a computer hardware tech) It shows 11.7v unloaded when plugged in, and comes up to 11.8 when I plug a load on (HardDrive). 12v at 6 amps. If you want it I'll ship it to you for 10 bucks assuming your in the con US 48. You would just use the yellow and black wires off one of the connectors. E mail me if your interested
I am using the 25 A one from Radio Shack (bought it while it was on special for $69 I think) and am totally happy with it. I made me a little box with a Y harness in there so I can hook up two chargers at the same time. No problems what so ever.
