Building converting a battery for a friend but running in to problems. The light setup he has is http://www.bikelights.com/Products/solo_logic.htm with a nicad battery 7.2 L&M sells a 11.4 lion.
What I did was order a lion 11.4v from all-battery.com, opened the nicad pack and replaced it with the lion (which fits like a glove btw)
So it works sometimes but when its fully charged it wont even turn on.
My friend's theory is the PCB protection on the board, when I first plug it in spikes to 12,8v which the pcb thinks is a short so it shuts the battery off.
I know the battery works though I use it to power other lights and is fine. But the solo logic is finky
Anyway for me to get this to work, or trick the PCB?
