The solar lamp most commonly used mode is mode 18650, like Tesla used :) Its dimension is φ18x65mm, it is small and suitable for the small solar wall lamps. Its capacity density is over 200Wh/Kg, higher than all traditional batteries. Its efficiency charging cycle could reach 800 times, so it is a perfect choice as the solar wall lamps’ power supply.
