SKYRC Quattro B6 employs a circuit that features four totally independent but identical power outputs which are powered 80 watts each. Total power is 320 watts. As a result , it can charge or discharge up to 4 packs of 15 cells of NiCd/NiMH or 4 packs of 6 series of lithium batteries simultaneously. The Quattro B6 has four individual cell voltage balancers at each output, so it does not require a separate balancer when charging lithium batteries (LiPo/LiIon/LiFe) for voltage balancing.
The SKYRC Quattro B6 allows you to plug 4 batteries into one charger simultaneously, and it will intelligently and automatically charge all 4 of them at once to their maximum capacity. To top of it, the batteries being charged do not even need to have the same configuration. You can connect different chemistry（Ni-MH/Ni-CD/LiPo/LiFe）batteries into any of the charging ports. No more staying up late for charging batteries.
