Batteries Q

[Old man]

Hb2 charger is quet good i even use it for my t-rex when i need to charge more bat than my charger can handle

[badastinner]

yeah it didn't look like it was just a plug w/jst connector on it, like the one that came with my walkera 4

If the lipos have a balancing plug get the esky charger from helidirect. Its is only $9.99 and will trickle charge at the end of the batterie. I use mine allot and plan on geting one or 2 more. I like to charge more than one bat at a time.

the heli came with a charger that uses a different plug than the one for plugging into the heli. The only problem is it doesn't have aplug for the wall just 2 alligator clips that plug into it and then clamp on another battery. can i use an ac adaptor for this charger cuz it would really suc to carry around a 12v battery all the time

[raven_darkcloud]

yes, any 12v 500ma or higher wall adaptor with - -(0- + Negative out/positive in and the right size plog will work on the esky charger.

cool thanks! Also i have two 8.4v 650ma nimh batteries from other heli can i use them on my hbcp2 i know they won't last as long but then iwould have 3 batteries to fly with. Can i use this charger off my truck battery in the field or is that way to much?

Yes but expect to only get about 6 to 8 min flight out of them. My walkera 22e had 9.6v 900mah (home made pack) and a 10.8v 600 mha pack (stock) and I got about 7 min out of the stock and 9 out of the home made pack. Just cuz you got lipos dont discount the nimh packs cuz thats more air time even if shorter. you will get less lift out of the nimh bats (lower volts) but still good for a little more fun. On my 22e once i flew out my lipos i ran both nimh's that got me about 45 min of total airtime. My home made pack is simple to do.
2 radioshack 4 aaa holders drilled out to drop wieght.
black and red stranded core wire
one conector compiant with your setup
8 rechargable nimh batteries (900 mah is best)
one velco strap (to hold the batteries in)
Ca the batterie holders together, solder the positive of one to the negative of the other, and solder the remaining positve and negative to the connector. then you can switch sets of rechargable bats and safly recharg in a normal house charger from say energizer or rayovac etc. This is realy only good for hovering and light flying. Also I wired up a car cig adaptor with a 7808 voltage ragulator to 6 feet of 20 gage wire (22 shuold do fine) and a conector on the end to preflight my heli. This is good for testing servo and gyro only (on belt or shaft driven helis) for better power add one more 7808 in paralel per amp. I hope this is helpfull.
