Any pack 5s 25c will work well. If you run say 2x 5s 25c 3000mah in parallel you will get a 5s 25c 6000mah which will still be light and give good runtime. Which emaxx do you have ? as that limits the size of the lipo you can get, the new 3905 emaxx the lipo cant be longer than 160mm or wider than 45mm.. The rc-monster.com store has some great lipo and great chargers
