Your Mychron 4 will Eat Batteries when You use it Properly
If you run a Mychron 4 with any attachments at all you’ll find it eats through batteries in no time. If you rely on the little 9v batteries that run the Mychron 4 unit to power the whole system you will be let down pretty soon.
By far the best solution is to plug your Mychron into an external power source, but I don’t like plugging the data gear into the kart battery in case it drains it and ruins the race. I’ve also tried using extra little 12v lead acid batteries which seem to get shaken to death!
My latests battery is from a radio control model shop, and so far its been great. I use a 12v NiMh battery pack, and I carry a 9.6v spare with me all the time. The battery cost me £20 and a proper charger for it was £15. That kit has ended all my battery related problems.
