KD 32600x2 pac 3c discharge? Why not 5761 bulb then?

[Lumencraft (Matt)]

I have a KD 32600x2 li-ion battery pack that claims 5000mah with a 3c discharge like this one here. But when I installed a philps 5761 in my M*g 2d the light would not come on. So to make sure it wasent the light I dropped 2 AW C cells in with a stretched out tailspring and the light came on. Am I missing something? Why would this not work? Has anyone else tested the discharge limit on a KD pack like this?

Those packs have the overcurrent setting set too low. I have two of those packs and they don't handle bulbs that draw a lot of amerage at startup well.

You will need some sort of soft starting device.
