Pshaw, balance boards are for people who don't know how to hook up a lipo. As long as the balance plug has 0.1" pin spacing, just use a pin header and it will work 99.99% of the time. Maybe I'm being a bit harsh today, but I've already had my fill of incompetance at work and am a bit touchy.
And while on my rant: why another low cell count 50w charger? It's not the market isn't already flooded with them or anything. How about a few more high cell count/amp/power chargers? Like 20s, 20A, 1000w? Now there's a niche that needs filling IMO.
