</span>I'm done something similar but using a 12V bulb instead of a resister.<br>
It limits the current flow to a fixed amount and provides a visual<br>
indicator of charging. I believe it requires a supplemental smart<br>
charging circuit to properly top off and cycle the battery to maintain<br>
good battery health.<br>
