bigger batteries do provide more current.. i try Frankie i try..
take the normal.. 901.. when fresh of charge is at 4.2 volts.. when the charge me up light flashes its down to say 3 volts or less .. as the battery voltage drops so does the current.. keeping the batteries in the upper voltage half provides more current than in the lower half..
when the little battery goes flat very quickly its not possible to keep the battery in the higher voltage half..
a battery that runs for ten hours can be swapped every five or six hours.. a battery that only runs for one hour is too much trouble to keep in the upper half it would need swapping twice an hour.. ..
to put it another way halving the batteries actual run time which can be done with a decent battery improves performance.. just using the upper half of the voltage range will provide more current than running it to fully flat..
when the battery has spare capacity u can do this when it dosnt really have enough to start with u cant..
the battery goes from 4.2 volts down to 2.7 volts before its flat.. never letting it drop blow say 3.6 volts means better vapour and more current..
the battery will also live longer because it prefers a shallow discharge to a deep one.. so in real life usage a bigger battery will provide more current..
try fitting a 12 volt motor bike battery to your car and see what happens.. or a car battery to a truck..
a lithium cell operates between 4.2 volts (fully charged) and 2.7 volts (flat).. its pretty obvious in the upper half of this range things are going to work better than in the lower half..
trog
ps.. when i did use real 901 batteries i never let them go flat.. as soon as the charge light said done i swapped them over.. but this can only be done when a charger is handy.. things become problematic when away from a charger.. its when away from a charger the bigger battery really comes into it own.. lots of people are away from a charger for lengthy periods..
