Hyperion EOS 1210i Balancer?

So I do need to purchase the LBA10 also to charger my packs. The charger is more or less a brain and power supply what tells the balancer what to do? I should be able to charge a pair of 2s packs in series with the LBA10 (telling it that it's charging a 4s pack). Or do the balancer plugs insert directly into the LBA10 like the do on a thunder power balancer?
