||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 EX G3 or LG345 series. The manufacturers claim 45C continuous, with 90C bursts for 20 seconds, from these cells - that means that you can draw amp rates of up to 90 times the capacity of the cells (eg.1100 mAh cells can deliver up to 99A for 20 seconds). That makes these cells a natural choice for the new Electric Glider rules - with a hot motor you can draw up to 288A, for example, out of a 3200 mAh pack.
Hyperion also claim 6C 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 7.2A and take 10 minutes). They also last 7 times longer than earlier technology packs (give 7x more cycles under the same discharge conditions). They also deliver more power for longer - tests show that they have 40% more power at 70% discharge than previous cells. So, if you want high discharge at high voltage, these are the packs for you!
But there is more - and it is not steak knives - these packs come with a balancing plug that is compatible with 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).

Please note - LG345 packs have been discontinued - they have been replaced by a smaller range of G5 packs and HV packs are becoming the norm (click on the links).
