See my thread below "'05 HCH 1 IMA warning lights. Uh-oh." for full background on my problem. Now I've decided to buy a grid charger for my '05 Civic Hybrid. I've narrowed it down to either a Hybrid Automotive or a MAXX VOLTS. They both appear to have many features in common, but I'm not sure exactly which features are best. I don't want to go cutting into wiring, or have to send anything back to the mfr. From experience, can anyone weigh in and tell me which one is best?
