Each pack can be discharged at 10A which means 360W per pack discharge rate. Good rule of thumb is 3 packs for every 1000W of discharge needed to achieve the desired power output. Each pack being 183.6Wh if you wanted 2kwh of energy storage you would need around 11 packs (5.5 packs/1kWh). Roughly 100W of charging per pack since the charge port is rated at 3A. You can charge using the discharge wires to charge faster but you would lose overcharge protection. The thinner black wires are the charge wires, the thicker red and black wires are the discharge wires.
