If you have 3800s or 4200s and you "put them in until the lights go out" you will kill runtime on those packs. The only way you can safely use the zero thirty with those cells is to stare at the bulbs and remove the pack from the tray as soon as the FIRST light goes out. Then use the end positions to discharge the other cells one at a time until the light just goes out. This was described the the TQ Cells support thread.DARKSCOPE001 said:the zero thirty is a good tray but it does not realy equalize the cells. it does to a point but to realy get a good equalization you will need to put them on a battery tray like the tekin or the trinity. the zero thirty is good for bringing them down whith charge still left on them. just put em on that till all the lights go out then put them on an equalizing tray. and after they are equalized then store them for a week tray them before charging charge and repeat. at least thats how I do it
HOPE THIS HELPS
That statment can be somewhat "misleading". The Tekin tray does cut off but it does so at .5 at each cell. As long as you take the newer packs off when the lights go out (.7) you should be fine.The advantage of a unit like the much more and the Trinity is they cutoff automatically,unlike the Tekin and some of the other units mentioned
.5 & .7 both are to low a cutoff for todays cells.Also like you "as long as you are there to take them off the tray" with the MM unit yo don't have to sit there and monitor the cellsOvalmanPA said:That statment can be somewhat "misleading".
