Hey Guys,
Working on a build and something is amiss.
Flashlight host with 2x18650's, fully charged. (trustfire, cheapos)
Properly heat sinked 1.8A Jib driver that I bought from Mohrenburg months ago.
3A Test load from Jufran. Jumper set to pin 4.
Reading the voltage across the resistor and I get 1.5A, and then slowly after about 20 seconds climbs to 1.67A... however after 30 seconds the test load is getting way too hot, the diodes and resistor can't be touched. So I turn it off.
Should the driver be going straight to 1.8A? Is the driver bad?
Are my batteries not able to provide enough current? I have two good sanyo's I bought, however their contact points are shallow so I'd need to rig them up somehow else..
Thanks!
