ok i just bought the lrp quadra pro 2 charger for a steal and its a 50 watt charger that can only charge at 5 amps at its max. its ok for me because thats what i charge at anyways but this charger only charges 3.2 amps on a 4cell 5000 this is straight off the wall by the way. if i put this on a 14 amp power supply will the charger be able to charge at 5 amps continuous? if so where can i get a cable that can hook into a power supply? it only has the 3 prong for the wall.

thanks in advance

the charger will run just nicely on the 14 amp power supply.
the power supply will do hardly any work and wont even get warm with 5 amps running thru it

i dont understand the 3 prong in to the wall bit... sounds like it might be an australian power plug???

do u have a photo of the power plug u can show us?

Changing to a DC supply will not make a difference unless the charger has different power rating for AC / DC

If the charger is rated at 50 watts you will get nowhere near 5 amps with a 4s battery pack

Amps = Watts / Volts

Assuming your pack starts at 12v you will see 4.16 amps at the start, and it will get lower as the voltage rises

50 watts divided by 16.8v = 2.97 amps (at the end of the charge when pack is full)

What you seeing is the charger limiting charging current to stay under its 50watt power limit. It won't make any diff running it with DC unless the chargers output power increases using DC. The chargers I'm familiar with generally have a little more output power running as a DC charger, but its slight like 50watts on AC and 63watts on DC. This is what the Triton 2 specs show for example.

That would only improve charge rate marginally, 63w/16.8v = 3.8a. You will not be able to do a complete 1C charge rate on a 4S lipo with this charger.

ok sounds good just was wondering if i switched to a power supply would i get that constant 5 amps. thanks for the info guys.its greatly appreciated!!
