Prices based on Hyperion 25C 3S at Lipo.com
HAIYIN gets $10.69 for a 3S 20C 500 and $27 for a 3S 20c 3300 and $28 for a 3S 30C 3300.
This to me means their small LiPoys are not really all that good of a deal while their large ones are a great deal if in fact they stand the test of time and if they will increase the approved charge rates to 3 to 5C and if they will offer a reasonal warranty .
I suspect its an economy of scale situation. The small capacity packs (500mAh) require just as much labor to manufacture and assemble as the big packs do. they use the same balance plugs and connectors. The difference between the small and big packs is the materials only which may be a small part of the cost factor. Think of it this way. Sometimes it takes just as much time and labor to build a small model as it does to build a large model. The difference is in the cost of the materials.
