Ah, ok. It was being referred to as a 0-30. I've heard of ppl trickle charging a pack to help equalize cells and return run time and voltage. Of course this is done during the week and not on race day. After the trickle charge is complete, store until race day. At the track, discharge with the Reactor30, try to keep the cells from overheating with a small fan, about 90-100 degrees during discharge, then equalize on the Smart Tray. Once they are done on the Smart Tray, place them on the charger after a short rest (about 10 mins tops) and charge. In my experience with equalizing cells, they seem to take a better charge if you get them on the charger as soon as possible. From what I've read about batteries, it's the rate of self discharge between cells in a pack that really throw the cells out of balance. Check this out.
The bottom paragraph on the link above describes the importance of equalizing packs before every charge.
