Looking for a 7s + balancer

[lincpimp]

So I would like to find a 7s balancer. I would like something I can charge thru, and will interrupt the charge sorta like a lba balancer does. But I can handle a stand alone like the astro blinky.

Or a cheap charger that can do 7s plus. Even a 50 watt charger would be fine, not looking to set the world on fire, just looking for a solution to keeping my milwauke v28 7s emoli packs alive.

Also, how are 7s packs usually wired? With a 4s and a 3s tap? Or a 5s and 2s? Have not seen many 7s specific taps. What does the hyperion 720i use?

Thanks guys, as always the pleasure was all yours.
