whats the deal with chargers that do up to 15 nimh cells?

[dana]

i was told that you cant charge two packs at once with an adaptor, it has to be one pack. i dont get it.. i have two 7 cell packs for my proboat... why cant i use an adaptor? wouldnt that be the same as if it were 1, 14 cell pack? should i just connect the two packs? someone please explain this to me because now i have two chargers. thanks , Dana

[Spot Me 2]

I never had a problem charging 2 packs at the same time.

[dana]

did you use an adaptor? only reason i want to know is because i almost bought a charger that could do 15 nimh plus lipo, as in the future i would like to get into lipo's when these nimh backs can take no more. instead i ended up with another charger that only does nicd nimh cells. its one of those mrc 820 chargers plus my old vision peak 2 to do both my packs at once. is the guy who sold me this thing full of *!***!***!***!**?

[Jeepers]

I used to charge 2x 9cell nimh packs at once never had a problem! made a parallel adapter worked great.

[dana]

ok...so should i just buy the one i want and make a parallel adaptor? why did this guy tell me i cant do that. i suspected he was a moron when he told me i cant but i dunno...he owns an rc business and im still kinda new

[dana]

anyone else?

[JimClark]

How are you running them in Parallel or series?

[dana]

in series jim =)

[JimClark]

Don't know who told you that info or what charger you are using but I have done it for a long time and never a problem. I think they don't know what they are talking about but we need to know what charger you are using.

As long as the charger can be set, or recognizes automaticaly, the number of cells your charging your fine. The charger doesn't know if they are all in one pack of in 8 different packs. It just sees voltage or cell count. If its a quality charger you should have no issues charging multiple packs.

[dana]

well i havent bought the charger yet, i wanted to get something that can do up to 14 nimh cells, because thats what im running now, but does lipo too because in the future i want lipo's. any suggestions on a chrger in the $150.00 range? right now i have a vision peak 2 to do one pack, and gus at the rc shop sold me an mrc 820 to do the other pack... i suspect this guy is an idiot. he says if one of my poacks if half full and the other is completely dead the charger wont realize it lol, i was like WTF?!?! when would 1 pack be totally dead and the other half full lol i run em in series lol how could that ever happen? lol i dunno am i wrong?

[dana]

also have you ever heard of the GT power chargers from rcstation? theyre ridiculously cheap...im talking 50 bucks for the equvilent of what venom sells for $150.00. im wondering if these are any good. rcstation also has battery packs nimh and lipo from intellect for insane cheap prices... are intellect batteries just garbage?

[JimClark]

Are you running the Sub c's in pairs? Then you will be just fine but he is right it is not good to charge one pack that is real run down and the other that is say 3/4 full.

[JimClark]

personally I like Hyperion chargers.

[dana]

i run them both in series.... the way the boat is set up to run factory

[dana]

meaning the boat is getting 16.8 volts from the two packs... in parallel the mah would be doubled but only running 8.4 v. i am correct on the series parallel thing?

[JimClark]

you will be just fine with charging them in series
Yup on the series vs Parallel

[dana]

right. thats what i thot. maybe he was confused about what i was saying... but either way it would be awefully hard to get one 3/4 drained and one totally drained no matter weather it was run series or parallel correct?

[JimClark]

he is thinking you are running them as single packs

[dddmx3]

I have a thunder ac6

http://www.hobbypartz.com/thac6smbachw.html

works great i charge both my lipos and nicd, and you dont need a power supply.. its ac!! and it comes with a usb port, you can watch your batteries charge on a graph. plus shipping is like 5 bucks. i love my thunder ac6

:buttrock::buttrock:

[dana]

yeah that must be it jim.. that and the fact that he didnt have any chargers in stock that i was looking for. he said i have to buy new chargers if i want to switch to lipo of spend 300 bucks on one that does both types. maybe he just wanted to make the sale, but i have my receipt lol and WILL be returning what he sold me for what i want and knew would work just fine for my applicatioon

[dana]

wow that looks a deal. no problems ever? did it come with instructions too? i like to know what the hell im doin lol

[dddmx3]

no problems what so ever. plus thats where i got my 5s 5000mah lipo for $60!

[dddmx3]

oh yes it did, but the website has a video on how to charge just watch that!

[dana]

well my GF says this will be my b-day present! 2 weeks! yeah that thing looks perfect. and awesome price!

[dddmx3]

Thunder ac6 right? It took a 5days to get to my house lol

[dddmx3]

Remember you need to charge at your mah rate If your battery is at 4000 mah then charge at 4 amps or like if it's at 5000mah then charge at 5 amps!

I struggled with what charger to buy for a long time-- I finally bit the bullet and purchased a hyperion duo 3 charger and a 350W AC power supply... it was a lot of $$$ but I love the darn thing-- charges anything I can imagine, and very fast. Between my son I and we have 2 boats plus a rescue, and we have a LOT of packs to charge... the Duo is 2 chargers in one, and the time I save is worth the extra money big time...

[dana]

yep, its sorta like my vision peak 2. adjustable 1,2 and 4 amp setting. my nimhs are 4200 mah so ill charge at 4.2 amps. although im starting to get the need for lipo's so that will be next. ch33rs!

[JimClark]

look at the Hyperion line of chargers

[JimClark]

I have a pair of these
http://rclipos.com/HP-EOS0606i-DC.htm
Might actually be willing to sell them if I can find a deal on a used Hyperion duo

[dana]

Why do you want to sell them?

[JimClark]

I would only sell them if I can find a deal on Hyperion Duo which has more power and two chargers in one.


Why do you want to sell them?
