Next tester upgrades

To get cleaner traces, I built pre amplifiers for both the temperature and cell voltage signals, as well as adding a low current charge control nichrome resistor. Now I can charge at 35A and switch automatically to 6A for a gentler finishing charge. The new temp sensors sit in direct contact with the bottom of each battery case at the bottom of the copper clip.The probes respond near instantly as I thermally couple them to the cells with a small dab of silicone thermal grease
