AW only makes one 14500 IMR high drain 600mAh battery:
Batteries : AW IMR 14500 3.7 V 600mAh
Efest makes an IMR that is 700mAh that is less expensive, but personally I won't recommend it. Over the long term AW is a better battery that will serve you longer. This is based on my personal experience with both brands.
You don't want to use protected Li Ion
batteries in the L Rider Robust because it is a regulated
mod using boost circuitry to raise voltage and requires the high drain capabilities of an IMR.
