Are Zippy Lipos safe with a Castle MMM Speedy?

[pasan]

Brian, I do measure my packs with my multimeter during and after charging. That's how I discovered the variance in voltage. I know it's probably nothing, but the pack in question has been doing this regularly for the past month. My charging setup is rather primitive, being just a Triton Jr with an Astro Blinky. I'm seriously considering investing in a Turnigy Accucel-6.
