I have a Havis Sheild 35W HID spotlight, and I have powered off quite a few things.
The trucks cig plug, a 12V SLA, all worked fine.
I tried it with a 3 cell Li-Ion pack, but I dont think it had enough voltage to strike a good arc. It would flicker and strobe.
Thats understandable if the voltage was too low, but,
Now I have 2 , 4 cell packs, and even when I connected them in parallel, the Havis will flicker.
Not near as much as off the 3 cell pack. In fact it seems to steady out at times, but still flickers from time to time.
These packs are made from LG 18650 cells, and BatterySpace protection circuits.
My original concern was that the protection circuit would trip due to the HIDs high startup amperage.
But that doesnt seem to be the case, as they dont trip, and the Havis continues to try to run.
What could be going on here?
The 4 cell packs should have plenty of voltage, they are actually toward the upper limits of the Havis input range.
Or, could that be the problem? Can too much voltage cause it to flicker also?
