I want to buy a fast charger but have no idea what I should be looking for! I want to be able to fast charge (from 12volts) my receiver packs and 7.2 sticks for my starter box. I have seen some on the net that state different amps and cell quantities but what about voltage? Or is the voltage irrelevant?
Ian i use a avionics charger it does all battery types including gell packs and you can charge them at what speed your batterys say you can charge them at and you do not have to tel it how many cells there are i paid £50 for it. I will find out who sells them for you and let you know.carl
As a general rule they should state how many cells (and therefore volts) they can handle and then give a maximum current load capability. In the main, the better chargers will be able to charge NiCd (nickel cadmium ), NiHm (Nickel Metalhydride), LiPo (Lithium Polymer ), LiIon (lithium Ion)and probably Pb (Lead Acid) cells. Don't be surprised if some state they can handle more than 10 cells (12v) from a 12v source - they have a 'boost' system that ups the output voltages to the cells.
Depending on your budget - get the one that has a minimum of two outputs, a high cell count capability and the biggest amperage something like a Pro-Peak Prodigy II @ £54 or if you really want to push the boat out a Chameleon6-330d @£125 or it's big brother Chameleon8-936g at £600!
In your case, you'll be able to use the charger for fast charging your flight batteries as well - an added bonus, a lot of new chargers will cycle your packs improving their performance as well - the best chargers are designed for the electirc fliers, so I would go that route and under utilise rather than buy cheap and be disappointed later.
