EXTRON LiPo vs. Panasonic NCR18650GA vs. LG 18650HG2
Test date: April 2017.
Subject: Panasonic Sanyo NCR18650GA 3.6V 3500mAh 10A Lithium-ion battery cell, with specific energy more than 250 Wh/kg.
The tests have been performed under certain battery stress applied conditions to achieve a goal of the unmanned aircraft – Project DELFTACOPTER
The Panasonic NCR18650GA cells clearly show a better result than the earlier tested LG 18650HG2.
The Panasonic NCR18650GA cells have a significantly higher capacity the Extron LiPo (an Extron battery pack was used by MAVLAB in Australia, into a previously competition).
The Panasonic NCR18650GA cells have a lower voltage level under load than the Extron LiPo.
The Panasonic NCR18650GA cells have a lower weight than the Extron LiPo.
The Panasonic NCR18650GA cells have a higher energy density than the Extron X1 Li-polymer.
The specific energy under typical loading is:
- LG 18650HG2: 10.80 Wh / 45 gr. / 240 Wh/kg
- Extron X1 Li-polymer: 10.79 Wh / 61 gr. / 177 Wh/kg
- Panasonic Sanyo NCR18650GA Li-ion: 11.97 Wh / 47 gr. / 255 Wh/kg
