The storage battery is lithium-ion battery packs, consisting of two packs, each composed of 27 single cells in a 3 parallel 9 series configuration. The nominal capacity of the pack is 70 Ah, and the working voltage is 28.8–36.9 V.

Power Capacity and Power Capability | All About Batteries

To get Wh, multiply the Ah by the nominal voltage. For example, lets say we have a 3V nominal battery with 1Amp-hour capacity, therefore it has 3 Wh of capacity. 1 Ah means that in theory we can draw 1 Amp of current for one hour, or 0.1A for 10 hours, or 0.01A (also known as 10 mA) for 100 hours. However, the amount of current we can …
