Hyperion Batteries LCL

Data Page

Pictured Above is the new Hyperion LiteStorm CL 2100 3S, 11.1V 33.6A max continuous pack. The "CL" series offers high capacity in a light, compact package. We recommend the 2100 for pilots who want the benefits of strong performance in the range of 12A~33A, combined with long flights, at a bargain price. For example, the pictured 2100mAh "3S" pack is extremely popular in 400 to 480-class aircraft, and micro helicopters such as the Zoom/Shogun and Trex 450 Series. Such models typically draw about 30A at maximum and average 12A~20A throughout a flight.

All Hyperion packs are made in South Korea, by leading manufacturers who have the highest standards for performance ratings and quality control.

The pictured multi-connector (at top right of pack) allows tapping into each cell individually to check cell voltage and re-balance when necessary, and supports the Hyperion LBA10 Cell Balance Adapter. Note that Hyperion packs may be charged via the main wires like any other lithium pack, but that the multi-connector also gives you additional diagnostic and charge safety options.

All CL Series packs come with high-quality, flexible silicone cabling sized appropriately for expected current draw, and foam end caps to reduce chances of impact damage.

The CL Series 4200mAh packs are comprised of 2100mAh cells in an integrated "2P" parallel pack. These are specifically designed for large Electric models and Engine Model conversions to electric power. While some makers are producing high capacity packs in long formats, you'll find that it is almost impossible to balance most models with these. The 4200mAh CL, on the other hand, have very compact dimensions, and allow easy adjustment for correct CG balance. In engine conversions, you'll find them a perfect fit in the fuel-tank bay for almost any model.

The 4200mAh packs are just right for use with Hyperion Z3025 and Z40 motors, in the range of 38A to 67A peak, depending on the type of model, cell count, and motor chosen.

Above is a graph of CL2100 single cell, from data supplied by the manufacturer. You can see that the voltage and capcity performance are excellent at 16C rate. This cell was probably on first cycle, as we find that after the first few high-rate discharges the CL2100 settles about 0.07V lower on average. (settling with all lithium cells, so be careful when you consider data adduced by makers and sellers!) That is still an extremely healthy 3.36 average voltage throughout a 16C discharge. Note that the lab cut-off voltage was 2.5V, and that we recommend 3.0V cut-off for these cells in RC use. At 3.0V cutoff, delivered capacity at 16C rate is about 95% according to our own tests on well-cycled packs. Very nice! Cell temperature can exceed 60 deg celcius if true 18C "continuous" discharge (or higher) is maintained, so we recommend 16C as the max true continuous rate, and 22C for 15 seconds or less in competition glider or E3D events.

Capacity and Current:

The rated capacity for each cell type is the minimum guaranteed by manufacturers at “2C” discharge rates, by industry practice. Capacity is a measure of how much energy can be drawn from the battery before it is completely discharged. A 1200mAh cell (1.2Ah) can deliver 1.2 amps for one hour or more, for example. When connecting packs in parallel, capacity is multiplied, as in the "2P" example below - two packs wired in parallel. (see bottom of page for info on parallel harnessing).

The ability of a cell to deliver current, or amperage (A), is often expressed as a multiple of capacity (C), as shown below:
