Pila/Copia Li-ion, I haven’t seen any discharge graphs yet, are there any threads with these?
Re: how well do these handle the higher current draws? 1C should be find, but what about 2C or 3C? Thinking of mods I haven’t seen yet?
150s(50+mm length) is the CR123A dia cell of only 1000ma (16.5mm), while the higher cap 150a is 18mm and 1200ma. Do these handle higher current draws and maintain voltages to keep the light bright?
How about the longer 168(68mm length) cells of 1400ma & 1800ma, I’l like to see discharge graphs of all of these.
If the 150s can handle 3C discharge; then we have a potential 20 min. runtime, much cheaper competitor for the Surefire 10X, 500-600+lumen 'flashbulb'; “mini-Aurora lite” in the making. Can anyone guess which host/bulb $70+(sans cost of Pila/charger combo) combination I’m thinking of?/ubbthreads/images/graemlins/evilgrin07.gif
From perusing kakster’s M4 comments on this thread, it maybe be possible?
kakster's notes on Pila 168's/M4 currents-outputs
There is this infamous Simon guy, who works for a company that designed the Li-phosphate battery for the new Megaray 175w, that claimed on RC forums, a similar cell chemistry 18650 cylindrical cell was weeks away from announcement. Hopefully this is not vaporware, and we’ll see this kind of Li-Phos or Li-Sulfur cell technology later this year w/higher capacities/good discharge graphs, to make fiendishly high output mods possible…before the 10w-16w HID’s of the near future takeover.
