24.5 miles with speaker

It went only 24.5 miles with the speaker, extra food, & camera. The speaker wasn't much better than silence, because it was 5 hours of the same old song. Audiobooks are a novel concept, there aren't many good ones. Getting the extra mile would be just a matter of another 1Ah battery somewhere. The trick is when connecting a fresh battery to a drastically discharged battery, the inrush current hits 5A at only 11V. Wiring 3 batteries in parallel would fill it with unused connectors most of the time. There's also discharging the 1Ah battery early in the drive, then putting in the 5Ah battery. This wouldn't work because the 1Ah battery would discharge far slower in the beginning. There's also carrying around a terminator & driving just on the 1Ah battery in the end.
