Re: dynohub chargeing a battery
So far all I've done was to keep my lights on to regulate charging current. But I'm running about
35W of halogens and LEDs. 6W would be break even in my case. I've got a 10W halogen on a front torpedo fender light and running that just uses a little more than I'm charging. All it does is prolong the time my battery (7ah 12V SLA) will
provide light. I'm going to add a volt and amp gauges to monitor the charge level on mine. Goal is to keep the charge (amps) as close to zero as possible
With the bottle units if you get too much charge you can simply flip it out of the way. On the hub
like you are using a switch like you mentioned might be a good idea. Just keep your wattage around
3W give-or-take and you should be good.
