This is the Revolectrix Cellpro Power Lab 8 Battery Workstation, capable of charging, discharging, monitoring, or performing multiple cycles on any current or future battery chemistry at alarming speed; the PL8 represents the end of all speculation about who sells the most powerful battery management system in its class for the best value. At $0.17 per WATT, it blows the lid off the competition & represents unprecedented value. The Cellpro Power Lab 8 (v 2) Battery Workstation directly supports all Cellpro Revolectrix battery packs. FMA sells adapters separately to interface with various manufacturer's batteries, including the safe parallel adapters which can be daisy-chained to allow simultaneous, safe parallel charge of multiple packs. Safety The charger will never let you charge a Li Po by selecting the wrong cell count. It knows how many cells are connected by monitoring charge voltage on each cell in the pack individually. It performs an entire series of tests to make sure the battery is hooked up correctly to the charger before it ever even starts to charge, checking for valid voltages on each cell, reverse polarity conditions, reversed node wiring to name a few. Reliability Take top-notch components capable of handling all of the stresses associated with super-high power, high voltage operation; things like an over-sized heat sink, extra-heavy 10AWG input wire, twin cooling fans & a gigantic sendust core toroid inductor to handle higher input current & combine these with
