RCGroups is a fantastic forum for learning tons about chargers, batteries, electronics and electrics - not just about RC equipment (cars, planes, heli's ect.) I've have learned a awful lot there and have this great charger because of my time spent there. I don't see much in the way of threads on high power hobby chargers so I thought I post a teaser. The PL8 has been out for a couple years and is capable (with a the right DC power supply) of providing up to 1344 Watts of output power to charge multiple large capacity, high voltage, balance wired Lipo packs. They just released their new MPA parallel charging board shown in the pics which will handle up to 6 each, 8S packs packs. Before, there was a small board for each pack - more spaghetti. Here, I'm charging 4 ea., 6S/3000 mAh Blue Lipo brand Lipo packs in parallel (used for my Megaray) at a total of 12 Amps (3.0 Amps each). I charge at 1c but my 12 Volt, 55 Amp PS is near maxed out - according to the PL8 software so a few minutes later, it dropped down to 11 Amps. There are many, many safety algorithms programmed into this charger and input current limits is one of them. The charger will accept up to 30 Volts input and that's what's needed to unleash the very large current flows. If I had the right supply and I wanted to, I could charge these 4 packs from completely empty to full in about 15 minutes. The charger can be used by itself or controlled by the included PC based op system which is much easier and faster. There are 25 Preset pack "slots" to set up your regularly charged pack combinations so you can set every pack up just once and then choose it when you're charging that pack combination. You can charge as low as 10 mAh and up to 40 Amps. You can change termination Voltage and just about all parameters involved in charging. Of course, it's an "all chemistry" firmware upgradeable charger. You can make your own parallel charging cradels for charging up to almost any practical number of cylindrical cells. I have a 4-cell cradle. The only real downside to the charger is that any Lithium battery with a cell count of 3 or more, must have balance connectors and they must be connected for the charger to allow it to be charged. I guess that's not really a downside, but a safety point.
