Right now I have a Turnigy 1 to 8 cell 150Watt balance charger that work's good.I was told that the iCharger 2 to 6 cell 250Watt charger will charge my 5000mAh 6 cell pack's a little faster so I bought one.It's been on back order for a bit and I can stop the order.Maybe get another pack but im kinda wondering if it really will charge faster.Im in no hurry to get it as my Turnigy is working fine but if it isn't any better,i'll stop the order.What do you guy's think?Will another 150watt's and 3.0 more amp's make a difference?How much faster am I looking at between the 2 charger's?Guess I really wanna keep the iCharger but now im not sure if it's really worth it over the Turnigy Accu8.

I've got the icharger 106 (250 watt) and 206B (350 watt) and would recommend the 206B for a significant increase in charging power if the price isn't that big of a difference. Also what power supply are you charging off of? It it can handle the 350 watts, then go that route, if not, then the 250 would be ok.

What I do is parallel charge my 2650 batteries as one 6 cell 5300 mah battery but will do a comparison using your figures.

So watts = amps times voltage means watts = 5 amps times 22.4 Volts (or you could use close to 25v figure as that's what your battery is going to be at right at the end of the charge) so watts equals 112 watts to charge at 1 C roughly, actually probably closer to 115. Right now you are able to charge at a little over 1 C at 150 watts on the Turnigy. If you want to charge at 2 C then just double your 112 watt figure which is 224 and as you can see the 250 watt will give you that. It will also almost (not quite) half your charge time. Now if you decide to parallel charge two batteries at the same time, then you will essentially be charging one 6S 10,000 mah pack at 225 which would be 1C sent to each pack. This is where the 350 mah charger would come in handy as you could charge 2 packs at close to 2C.

As stated, I parallel charge and send a lot of amps to multiple batteries and save a ton of charge time.

I hope this helps.

That does sound right (still learning this charging stuff) because even though my Turnigy say's I can charge at 7.0A,I only charge at 5.7A.If I try charging at 6.2 to 7.0A,it start's getting pretty warm.Both of my Turnigy 2650mAh 6 cell pack's take about 25mins to charge and my 5000mAh 6 cell's take about 50min's to charge with the Turnigy charger..

Now if I understand this right,it take's about 150W to charge at 5.0A which is 1C right?Im broke and slowly upgrading so i'll stick with the 250W iCharger..
With the 250W iCharger,I can charge at a full 10.0A and the charger shouldn't get warm because it's putting the watt's out to push the amp's?If so,my charge time on the 5000mAh pack's should be around 25-30min's each and around 10-15min's on the 2650mAh pack's?If im right,that's more than enough until im ready to buy a bigger charger..

The power supply im useing is a 600watt PC supply which work's perfect.

Thanks so much for the info ...

Yep sounds like a good plan. My 250 watt charger does get warm drawing 10 amps to charge my 6S "5300 mah" and "6000" mah batteries at 10 amps, but it's got a built in fan that keeps it cool.

Yes if your 2650 packs can handle 3C charge then you can charge them with 10 amps and turn over around 15 minutes.

W = A X V so
W = 10 amps times 22.4volts
W = 224 watts to charge your 2650's at 3C

or

W = 2.650mah X 22.4 or 60 watts per C

To charge at 1C figure 60 watts
2C 120 watts
3C 180 watts etc..

I'm using an HP 575 watt server power supply.

I have the icharger 106B+, it will only give you 250W at 13.5V input, at 12v you get around 200W or 9 amps into a 6s li-po.

Keep an eye on your cell voltages, check them with a good multi meter, the ichargers can drift off calibration but they can be calibrated fairly easily. Google how to do it. Mine was quite a way off.

60% of the time, it works every time!

FWIW, most pc power supplies are rated for all outputs. The 12V rail is usually only about a third of the total PS wattage. So, if you have a 600watt PC power supply, only about 200 watts will be available at 12V.

Mine works great. Google TJinguy and go to his website to see how to convert it to hobby use. I've run both my 106 and 206 chargers wide open parallel charging my 600 batteries and it doesn't skip a beat.
