Are these protected(pcb?) and also, what makes these better than a standard Lion batt? (pardon the ignorance)
redalert, they dont have a PCB they're a safe chemistry so they're more stable and dont vent or flame..
now for the what makes them better aspect...
lets say you're using a 510 atty at 3.7V on a mod that takes a 14500 battery...
the amp draw on a joye 510 atty at 3.7V is 1.61A (2.47A on a LR atty)...
the max drain rate on a AW protected 14500 battery is 1.5A ....so the battery gets overstressed (leading to reduced overall life of the battery) and doesn't quite put out the power it could...
Now I dont know the discharge C rating on these high drain IMR batteries..
but if they are a 5C discharge like the BDL ones then the max drain rate would be about 3A...so about twice as capable of pushing the power and meeting the amp draw as the regular 14500..
in other words running a LR atty on these won't overstress them
