Anyone try or have a suggestion on a type of voltage regulator for electronic ignition modules? I want to get away from using Nicads and such and start using Life or A123 types. Problem is the ignition modules I have on some engines are 6volt max and I don't want to risk ruining or burning one out. Life type batteries are 6.6 volt and will reach over 7 volt when charged. I've seen some like Mpi that are rated 5amp and up to 10 max. But they are not cheap. Also seen some from HK that are much cheaper and run 5 amp to about 71/2 max. Not sure if these are the correct things to be using. Any thoughts? I need to get quite a few of them.
