Two 2s 5000mAh 30-40c or higher c rating. A single 2s pack is 7.4 volts. Connect the two batteries in series for 4s, which is 14.8 volts. Series double the voltage while mAh and c rating stay the same. Connecting in parallel doubles mAh only. The c rating never changes no matter the connection. You can also run two 4s packs in parallel and have a bit more run time. MG owners will chime in and give you more advise on what they use as I do not own one.
