FAQ of lithium-ion polymer:

• How long will customers receive samples?
  Generally 7~10 days. We will do capacity grading before delivering.
• What’s the MOQ?
  We can accept small trial orders, such as 500pcs, 1K pcs
• What’s the product warranty? When does it start?
  The period of warranty is one year from the date of shipment. HLC guarantees to give a replacement in case of a battery with defects proven due to the manufacturing process instead of the customer abuse and misuse.
• Which protection does the battery have?
  It can protect against short-circuit, over-charge, over-discharge, and over-current.
