Not sure its a 100watt charger based on the lipo specs - that's no diff than the Accucel-6 which is rated for 1 - 6S and is only 50watts.
The 1-14cell NiMh at 5a spec is what makes it look like its 100watts charger.
I don't understand why they don't simply say what the power output really is. Its like they're hiding something to try and justify the $170 price tag. LRP should know we need/want to know a charger's output power.
