Temps: 2C, ran to the waste xfer station & back, then downtown & back. Reasonably lucky traffic situations (preserving momentum at critical spots, DWB). But went too far - 1st gear crawl up last hill, had to DWL to keep it above 5.25v / batt. |

Next day: drove 12.x km, had to feather in 1st gear for the last 2 km to keep the pack out of danger territory. Don't have energy data though because Ivan recharged it. Temps were around freezing. Looking forward to swapping packs again to see if there's a big difference between them. |

Water level was too low in some batts. This was probably the reason the pack wasn't getting up to full charge to shut off the charger. Perhaps efficiency will also increase now that I've topped them all up. |

More evidence that going further before charging = higher fuel economy. However, there were 5 days in this charge cycle (more days = lower fuel economy from battery self discharge @ 1-2% loss per day); recharge time was 16 hours on the 24v/10A (nominal) charger for 3.58 kWh |
