Same charger?

[simplechamp]

Don't have experience with those chargers but they look the same to me, probably are the same hardware.

It's not as much the cell count as the mah capacity that matters here. Those 50W chargers can charge up to 6s lipos, but the rate that they will do so is going to be limited. You would only be able to charge a 4s lipo at 2.5-3A max and that would be pushing the charger to it's limits.

Another thing to think about is the built-in power supply. If you buy a quality external power supply you can use it with any charger. Whereas with this built-in one if you decide to change chargers the power supply is gone too.

Not trying to discourage you or anything. I just don't want you to buy this 50W charger and then be limited by it. That's what happened to me. I thought I would save money and get the 50W, thought it would be fine. Then when it wasn't I had to buy a 250W model and wish I would have done that right from the start.
