Default Accucel 6 charger and Paraboard..only 3.4amps output

I bought a paraboard from Buddyrc, nice product.

Hooked it up to my Turnigy Accucel 6 charger which says it has 6amp output.

Plugged 3 4S 3000Mah batteries into the Paraboard and programmed for max. 6amp charge.

Accucel 6 will only give me 3.4amps with plenty of power from the supply.
Why am I only getting 3.4Amps?

Your Turnigy Accucel 6 charger has a maximum rating of 50 Watts. Since watts equals Volts times Amps, that will limit your maximum current output when using more series cells in your LiPo battery. (More cells equals more voltage = higher watts to charge your battery pack, assuming the same selected charge rate in amperes.)

So, you've got 4.2 Volts times 4 cells, that is 16.8 Volts DC. Maximum Amps output would be Amps = Watts/Volts, or Amps = 50/16.8, so maximum Amps will be 2.97 into a four cell LiPo battery.

The only way to increase your ampere capability would be to buy a higher powered LiPo charger, with perhaps 100 or 200 Watt output.
Something like this unit would do the job:

FYI, I've got two $$$$ Cellpro Powerlab 8 chargers with a 1344 Watt capability. Each is capable of charging my A123 battery packs at 30 Amps, into the A123 battery pack. The battery pack is configured as a 6S4P for charging purposes.

For playing a bit with the currentlimits for chargers, for given number of cells, per type/make
www.scriptasylum.com
-> RC calculations
-> electrical menu
-> Lithium battery chargers ->
-> select your charger, click calculate et voilà
Also in the electrical menu
-> Charger calculator
Zeeeeeeeer handige site voor e-volk, loop maar eens door de diverse menu-items. Toevoegen aan favorieten?

Kyle,
Thanks for the detailed response..it actually all made sense to me!
I am going to get the iCharger 206B 300watt 20 amp charger.
That should work well I think. Should be able to charge upto 2C with 3 4S batteries on the paraboard.
Thanks again.

You're welcome!

Several of my club members have that iCharger, and are quite happy with it.

Let us know how yours works out, for the benefit of the wattflyer readers.

You might also consider the Turnigy Reaktor 300W charger. It's exactly the same charger as the 206b (even uses the same manual) but cheaper.
