Default best way to charge

New to electric and just getting started what is the best charger to buy and I would like to get a AC DC CHARGER AND I understand most need you to buy a power supply . How do you match a power supply ie what amps is needed and to go with your charger? Is it better to just buy a seperare 12 v battery and use this with your charger? Thanks in advance .

I like to spec stuff out in this order.

Model,esc,motor,ect. determines batt pack. Batt and desired charge time,current,speed determines charger. Batt and charger determine the input power (source)

I've been using The Triton 2 charger since it came out. Never any problems. It has both AC and Dc charger options. I can't find any instance of any fires caused by charging with a Triton. It shuts off when time runs out (you can set it) or the battery has been charged to full capacity.

Sorry for chiming in late, but if you're still looking or if anybody in the future is searching, here's a little info on chargers:

Some chargers are AC and DC powered.
When evaluating your DC input requirement, first find the max output - most chargers today are limited to a rate of 50 watts or 200 watts. That will dictate what size "brick" or power supply you'll need.
Let's say you look at a common charger like the Turnigy Accucell and it says "Max charge rate 6A / 50 watts." That means a 50 watt power supply is the minimum you should use with it at the max rate.
If you plan on charging big batteries with it - it will take longer. Let's say you get a big plane that takes a five cell 5000mah pack and you want to charge it at a standard rate of 1 times capacity (aka 1C) which is 5 amps... that would require 92 watts from the charger (18.5V * 5A) - but since that one is limited to 50 watts it would just charge at a rate of 2.7 amps (50 watts / 18.5v) and take about two hours at 0.5C rate instead of one hour at 1C rate.

Hope that helps.
