Polymer lithium battery and 18650, which is more expensive?
A little bit of the polymer is 10 yuan 1000mAH offer, 18650 is hard to say, the overall comparison or 18650 expensive!
18650 is currently the highest level of Panasonic Sanyo 3200MAH, and do not believe what high-capacity high-density that are virtual standard, the capacity of the polymer according to the volume so there is a large capacity, the price is almost it, Sanyo 2600MAH price of 20 yuan, 2600 Of the polymer is almost the price, but the 18650 battery relative to the polymer in terms of slightly higher risk, mainly to see your battery reserved space for what battery put in
18650 at least two 2600 parallel to achieve 5000MAH, and the polymer to do 5000MAH can be changed in the size range. According to the shape you need to do; but 18650 is currently only Panasonic Sanyo's monomer can do up to 3200MAH, you can buy 5000MAH polymer batteries. The price of expensive polymer, such as domestic: 5000MAH polymer prices in 35 dollars, 18650 also two parallel prices in 27 dollars. But the 18650 is much easier to explode than the polymer batteries, and I recommend choosing a polymer cell. Safety first
