2.Powerwall 2
The Powerwall 2 was unveiled in October 2016. Compaed with others, The Powerwall 2 had a 13.5 kWh capacity and was capable of delivering 5 kW of power continuously and up to 7 kW of peak power in short bursts (up to 10 seconds). After 5 years, 100000 Tesla Powerwall 2 has been installed. Compared with Powerwall 1, Tesla Powerwall2 use the larger 21-70 cells, which have a 21mm diameter and are 70mm long.
