I use 2 sets of IKEA LADDA rechargeables which seem to be Eneloops under a different name but at half the price: Panasonic Eneloop vs IKEA LADDA | Are They The Same? <https://www.slrlounge.com/panasonic-eneloop-vs-ikea-ladda-are-they-the-same/>
Also, there's info out there somewhere about adjusting the M100's low battery light and cutoff to better match NiMh batteries' 1.2V vs 1.5 I have some 1.5V AA rechargeable batteries at home which AFAIR are ZnFe technology but their shelf life isn't great and they seem to have disappeared from the market, replaced by those regulated Lithiums; anybody know anything about those?
