Choose simple easily obtainable and mixed liquid hydrocarbon storage containers with screw tops that suit any brand, any size, any age 2 stroke machine (and 4 stroke, even simpler).
5 litre fuel can and pourer for $10 or less each, stores ULP and 2 stroke oil, easily obtained at market prices and can refuel all brands, all sizes.
Gamble on the plethora of overly complex versions of https://en.wikipedia...ium-ion_battery encased in a myriad of proprietary housings that only suit a particular model/range that often becomes outdated/unavailable in a short period of time, no matter how good it is, the next model is better but the old/other brand battery packs don't fit.
And for serious commercial use, anything that is assembled from a large percentage of plastic components that have had the R&D $ spent on looks is probably not designed to last, the best option is to choose ugly but time tested.
