Correct, Ice does not have a balancer. This is a good one, easy to use that works well -

If you have a voltmeter, you can read the individual cell voltage via the balance tap. The Orion lipo - charge when it shows a diff in cell voltages, maybe every 7 to 10 times?
Lipos like Maxamps, I'd charge every time. Again, its how quickly the cells start to show diff voltages. I use a Hyperion 0610iNet charger with a built-in balancer and just balance every time.
