1	2000 Honda Insight, 5-speed, 269k km / 167k miles: IMA warning light & P1449 error code set around autumn 2010, then car sat unused from ~Dec 2010 - Jul 2011
2	Discussion of this project in the EcoModder forum:				Analyzing (refurbishing/repairing) a dead hybrid battery pack (2000 Honda Insight)
3	Super Brain settings: 7A charge, 5mV per cell peak detection; 10A discharge, 0.9V per cell cutoff; 20 minute cool/rest between each charge/discharge
