Comparing Ripple measured on Opple 3, for Emisar D2 (dual channel LiIon only), D3AA and KR1AA:
bottom right is KR1AA using almost full PWM at 1 lm on LiIon
overall the D3AA has the lowest Ripple when using Eneloop, followed by the D2
The D2 actually has slightly lower Ripple than the D3AA on LiIon.
