3.7V 70mah Lithium ion Battery Li-ion Battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others). It is also a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid one. High conductivity semisolid (gel) polymers form this electrolyte. These batteries also provide a higher specific energy than other lithium battery types and are being used in applications like tablet computers, cellular telephone handsets or radio-controlled aircraft.


  1. High energy density: volume energy density can be 300mWh
  2. Excellent security: no fire, no explore of short-circuit, over-charge, over-discharge, over-current, shock, vibration, crush, acupuncture
  3. Long cycle life: capacity recovery can be above 80% after 500 cycles
  4. High discharge voltage plateau: 3.6V discharge voltage plateau than 42min
  5. Environment-friendly: no PB, CD added
  6. Flexible size design subject to different space of application
  7. CE/RoHS Directive-compliant/REACH/UL/MSDS/UN38.3/IEC61233 standards
