I'm looking for a highly efficient battery that minimizes overheating issues. It should have an output voltage of around 650 volts and be capable of operating for up to 8 hours. Additionally, I need the battery to support simultaneous charging and usage. In terms of dimensions, the height should not exceed 30 cm, with a maximum length of 5 meters and a width between 2 to 3 meters. The power requirement is approximately 400 kW at a maximum voltage of 650 volts. Please provide details on available options that meet these specifications. Thank you!
