Recommend First Charger - LiPo + NiMh

Hi - I am building a slow stick (first RC plane). The kit battery is a NiMh pack which I will use to learn how to fly this thing, but in the future, I would upgrade the motor, etc. and use LiPo batteries.

Can anyone recommend a good "starter" 120V charger that can handle both types of batteries? I would also be willing to use a 12V charger with recommendations on a suitable power supply.

Thanks,

Pete

The "What charger" question comes up almost every day. If you do a search you'll have hours of reading. Plus, everyone is going to say "the one I have" or "the one I'm going to get".

pcs, in the budget range to handle a variety of batteries I would recommend that you purchase a quality charger such as the Bantam e-Station 301DX (~$80) or the Hyperion 0606i (~$100). For a bit more you could look at chargers by Schulze, ThunderPower, or Orbit. For a list of chargers with stats for each one I put together a thorough list you can find at www.progressiverc.com/Research.html

David - Thanks for the help. That is a Fantastic website; especially for newbies like me.
One more (stupid) question..........what exactly does a balancer do?

Thanks again for your help...

A balancer ensures that all cells are balanced at a proper voltage of 4.20V. Batteries can be charged without a balancer, but it is a good idea to balance the cells in a multicell pack at least every few charges, if not every time. The idea is that cells can deviate in voltage after discharge/charge cycles and when charged together some cells may be overcharged and others undercharged.

For example, in a 2 cell pack the fully charged voltage is 8.40V. In a balanced lipo this is made up of 2 cells at 4.20V, but if the lipo was charged without balancing one cell could be overcharged to say 4.25V while one cell is undercharged to 4.15V.
