No, use even less charging current say 70% or even lower.

I use 200-300 mah self-tapering voltage regulated supply just so all the cells get a better voltage stabilization

If you charge your batt at over 1C... the life span will decrease over time and multiple cycles. Not to mention, charging over 1C will probably significantly increase your chances of starting a fire

assuming its "broken in"...

You would charge it at 1C which is the recommended rate... thus taking 1.25 Hours... (1.25 Amp charge rate)

Feel free to correct me if I'm wrong guys... or if there is something you feel you need to add.

That is if you take it down to LVC. Yesterday I flew a TP 3S 1320 for about 12 min. When I got home I charged it at 1.15 amps and it took 47 min on an Astro 109
