Yeah 9C, and the Liperiors took it like a champ! They were mildly warm after, but not nearly as warm as I thought they might be. The battery connectors were the thing that got the hottest, and while they were very warm, it was not so much so that I was concerned theyd fail or anything.
The charger is an iCharger 456 Duo. 45 meaning 45A per channel, and the 6 meaning it can do up to 6S lipos. They make a 458 and a 4512 for 8S and 12S capability. They had older series that look the same but a little less powerful, like the 40X and 30X lines. Those have all been discontinued, but sometimes you still see them floating around.
iChargers are some of the best chargers on the market, and they have other models that are still powerful, but not 45A units. The DX6 or DX8 for example. Both awesome dual channel chargers and still capable of 30A/channel if memory serves. I also own an X6 and an X8 which are small dinky little single channel 30A chargers. 800W and 1100W respectively.
