iCharger 3010b and iCharger 306B
These are rated at 1000 watts, and the 306B is a 6S charger...but they both have a maximum charge current of 30 amps.
To get 1000 watts into 6S at 30 amps, each cell would have to be 5.56 volts. What am I missing? Granted, the 3010b can do 10S, and at 3.7 volts/cell, you hit 1000 watts at 27 amps. But I don't think the 306B can't hit 1000 watts charging 6S lipos at 30 amps. At 30 amps and 3.7 volts/cell, you're only hitting 666 watts.

306b
1000 watts is not a lipo specific limit 12 Life cells  43.2v (23.1 amps for 1000 watts) 30 amps @ 25.2v (756 watts) is the 6s lipo limit Cheers 



Thanks guys.
What is a better charger? By better, I mean least $/effective watt when charging multiple 6S lipo batteries using a paraboard or similar (and can stand up to repeated high amp usage)? The Powerlab 6 does 40 amps, enough to charge 6 3300mah batteries at 2C, but I am afraid there is something I'm missing.

When charging 6S, the PL6 will indeed offer higher power output if your power supply has sufficient voltage. IIRC, the PL6 will do somewhere around 850 watts on 24 volt input. Almost 30 volt input is required to hit 1000W output as it has a 40A input current limitation. The 306B is limited to 30A output so it'll take a bit longer to charge your 6S packs.
The 3010B offers nothing over the 306B when charging 6S lipolys. As such, it'd be wasted $, IMO, if one never planned to go above 6S lipoly. It'd be a tough decision for me personally. I have 4 iChargers (1 x 306B, 3 x 106B) and absolutely love them. I almost always run them at full current output and they have all been flawless. That said, I would love to have a PL6 for the extra 10A. Mark

A little misleading. A ~1520% increase in charge power does not equate to a ~33% reduction in charge time. A fair test would be to do repeated tests with an actual 306B compared to a PL6 using the same batteries discharged to the same voltage.
Agreed that the PL6 will have lower total charge times, but not by ~33% when charging 6S lipoly from a 24 volt source. Mark

Huh, guess I didn't see that.
Well epbuddy has the power lab 6 with a paraboard and the usb interface for $198 + shipping. The 306b (which includes usb) comes with a free paraboard for $160 + shipping. The 306b has ~50A input current limit compared to the PL6's 40A, meaning you won't need as much voltage from a dc power supply. If you've got a 30V+ power supply I'd go with the PL6. But if you're going to use a 24V or less dc supply I'd get the 306b. With a 24V supply you'd only get approx. 32.38A of charging current on the PL6, not much faster really. If you've got smaller than 6s batteries then you might like the extra 10A of charging current you'd be able to get that the PL6 has.
