The Molicel P42A 21700 battery is a top tier battery, beating even the current purple-wrapped king. It carries a typical 4100mah capacity and offers a continuous discharge rating of 30A (40A in cooler conditions, but stay safe out there). As you'd expect from a top level producer of quality like Moli, the P42A has a super low resistance, quick charging time and peak pulse discharging of up to 45A.
Basically, if you own a mech, you NEED to try these. After the excellent 20700 cells all around the world, the P42A is a best in show 21700. Check out Mooch's review here, of "one of the best batteries available".
