M is for Modular.We're finalizing development of our modular home battery system with our partners in Shenzhen. We present to you LIGHT M — our modular 4kWh battery pack designed and engineered for Roombus smart homes.Light M uses supercapacitor cells, and so it is both non-toxic and non-flammable. It is free from lithium and cobalt — which eliminates major present-day battery dangers like overcharging, overheating, off-gassing and combustion.Though previous generation supercapacitors had less energy density when compared to lithium-based batteries, new generation iterations are giving lithium-ion a good run for its money; without many of its problems.Light M can be combined into a battery bank of 20kWh — that's enough storage to stay autonomous for 2 weeks in your pretty Roombus. Happy You!
