Triton Charger

Here's a bit of info straight from Radical R/C's website.  

Here's the URL to the page: http://members.aol.com/davthacker/nimhfaq.htm

Wall Charging:

Here is how you calculate charge times for NiCad and NiMH packs. (MAH Capacity X 1.4) /  Charger  MAH = Charge time in hours.  For a little safety margin you might replace  the 1.4 figure with 1.6  . 

So, 1650 TX pack would work like this:  1600 x 1.4 = 2310.      2240 / 50 MAH = 44.8 hours. 

If the answer is less than 14 hours, then the charge rate is too high to be left unattended or too high to be used without proper peak detection. 

Keep in mind, you won't be running down a 1650 TX pack in a day of flying!  So, you will only charge it from dead one time most likely.  Most cyclers have a 120 charge setting.  This is a better overnight rate for this pack.   2310/120=  19.25 hours.  But, your 50 mah wall charger will work just fine as long as you keep the pack full and allow enough time to charge. 

Never charge a NiMH pack at a rate over C/10 unless the charger is designed to properly detect and shut down when the pack is full.  At a rate above C/10, all packs (NiMH and NiCad will begin to heat up after they are full.  A NiMH pack will heat up very quickly and excessively.  As long as you are using the correct chargers or rates, this is never a worry. 



Fast Charging:

Though all manufacturers recommend a maximum charge rate of C X 1, I have had good luck up to C X 2.  Above Cx2 is strongly discouraged. Any charging is ultimately up to you and in your control and consideration.  Just remember, the higher the charge rate, the higher the risk to the pack.  C/10 is considered the safest charge rate for NiMH or NiCad packs.

  All my NiMH documentation advises no more than a 1 Amp charge rate,
