After discharging the lowest cell down to 2.7, the module was rested for 2 weeks and today all of the cell voltages were read again. All of the voltages had drifted back up to around 3 volts with the highest being 3.096 and the lowest, 2.068 volts. The lowest half cell shifted from #5 to #9. The two flood lights were hooked up and the lowest half cell was taken down to 2.5 volts. Then the 40 watt bulb was connected and the voltage started increasing again. Once the voltage stabilizes, the 4 watt night light will be connected and the voltage drained until the lowest half cell is down to 2.5 again. Hopefully after a couple weeks rest, all of the half cells will be below 3 volts and I can start charging all of them up to 3 volts. This is kind of like top balancing the bottom and seems to work best to get them to all level out at the same voltage. Jack Rickard at EVTV reported that he was using 3 volts as his bottom balance voltage but this is before his module caught on fire, so I may check with him to find out what voltage he is using now.

Until next time,
