||Hyperion LiPo cells have earned a good name amongst electric fliers. Bob Hickman has reviewed them in his Airborne columns and spoken enthusiatically about them. They measure up - in performance, durability and incorporating the latest developments in LiPo technology.
The latest release of Hyperion high-power LiPo cells are called VX G3 or LG335 series. The manufacturers claim 35C continuous, with 65C bursts for 20 seconds, from these cells - that means that you can draw amp rates of up to 65 times the capacity of the cells (eg.1200 mAh cells can deliver up to 93A for 20 seconds). That makes these cells just right for the new Electric Glider rules - with a hot motor you can draw up to 200A, for example, out of a 3200 mAh pack.
Hyperion also claim 5C charge rates are possible and give up to 80% capacity to the cells (previously a 1200 mAh pack could only be charged at 1.2A and take one hour - now you can charge at up to 6A and take 12 minutes).
But there is more - and it is not steak knives - these packs come with a balancing plug that is compatible with the Hyperion chargers - buy these packs, and the matching active balance board, and you will have no more headaches with mismatching plugs. They also match the Hyperion range of chargers with built-in balancers.
Couple all that to the fact that these packs are smaller and lighter than most, and less expensive, and they present as a compelling range of LiPo batteries. In the chart, the number in the cell type column indicates the mAh capacity of the pack. The Series column indicates 2S (7.4V), 3S (11.1V), 4S (14.8V), 5S (18.5V). More details and photos to be added soon (message posted 23-9-09).

Please note - LG335 packs have been discontinued - they have been replaced by a smaller range of G5 packs and HV packs are becoming the norm (click on the links).
