For 6000kv stick to 2s lipo. Be careful with those cheap ebay lipos....also, are you still using the tt01 tub chassis? If so, check your battery size when yu get them. I couldnt get any to fit. Went to the 3racing frp chassis and a maxamps 3s lipo on mine with the losi xcelorin 4800kv motor and esc. Also have an ezrun 4300kv motor, but that has far less torque. Also if yu wanna mess with gearing check out hpi 0.6 pinions. Tamiya only goes up to 25t, but i'm using an hpi 35t pinion + the tamiya 55t spur. Anyways, back on topic. Try to get a lipo with a reputable name and small dimensions. Also, if you want long run times, try to stay around 5000mah. Also, get a decent lip charger.
