NMC (Lithium nickel cobalt manganese oxide) is a key ternary cathode material for lithium-ion batteries, with the chemical formula LiNixCoyMn1-x-yO2. It has a higher specific capacity and lower cost than unit cathode materials. Lithium cobalt oxide is one of the most widely used battery materials, but cobalt resources are increasingly scarce and expensive, and lithium cobalt oxide batteries have potential safety hazards during use

The sample battery can have two appearances.
(1) There is a small PCB board on the top cover of the battery, which is convenient for welding and wiring.

(2) There is no PCB board, and two contact pins are exposed.

Please tell me, which one do you need? (1) OR (2)?

In addition: the cost of shipping a sample e-cigarette battery to Canada by air is about $45 for 1kg or less.(≤1 kg)
