I've got two batteries. A hope 14.8v and a 14.8v lipo cell. The lights run triple Led XRE lights through one of those Black Cat technology drivers. So, why does the Lipo cell make the light so bright I get complaints from passing aircraft while the hope wouldn't make a mole blink.
I fear a scientific answer coming.
Can you monitor the voltage applied to the driver when the light is switched on?
If the Hopes voltage drops then its past its best.
Oh blimey hope not, I just got it off this forum. I'll need to hook up the battery to the multimeter and see.
You need to measure the voltage whilst the battery is under load, i.e. the lights are switched on. It could read 14.8 when sitting there, but drop dramatically as soon as the load is applied.
