The company earlier raised $7.5 million and is building manufacturing facilities in India.

What is a flow battery? It's a battery with tanks of electrolytes that effectively let the battery store more energy than normal batteries. The electrolytes flow or circulate through the system. The larger the tanks, the more electricity it can store.


Biggest drawback is cost at $2,500USD per kilowatt, about 10% above cost of coal fired plant.

38 kg (88 lbs) micro streamliner reaches 122km/h (75mph) on 192 AA batteries.

The phosphate-based Epoch batteries are equipped with an advanced management system that will monitor and adjust cell performance.
