• Advantage of GBS 2nd Generation Li-ion Batteries Compared To Thunder Sky Batteries:

  - 10% higher energy density by weight and by volume;
  - Superior safety performance due to patented new safety valve and pressure cap designs;
  - Batteries do not explode or catch fire when batteries are shorted or punctuated resulting in internal shorts;
  - More robust connection due to new electrode terminal design using four rivets or four screws per terminal; Prevent loose connections caused by vibration;
  - Reduced impedance due to improved electrode terminal design;
  - Improved cycle life;
  - New cell structure better facilitates BMS integration and battery pack formation, and improves air circulation.
