So I'm working on a battery install, and the battery, like any other, has 2 leads (pos and neg). Those leads go to the Power in terminals of the Bluerail board.
When the battery is depleted and needs to charge, I don't want to have to take off the shell. Can I put a charging port connected to the leads that I can access and plug in from outside, or will the charger damage the Bluerail board somehow since it's still connected to the battery as the charger is plugged in? Would I need to switch off the lead to the Bluerail board? I feel like this is pretty simple stuff, and the PS2 board doesn't mind when a battery is charging through the port, but that's not the primary system power either.
In simplest form, it would look like this (Similar to PS2 Charging port):
Edit: I found this info on the Bluerail trains site (not easy to find, but helpful). I'll need to switch the battery leads anyway, since the board will use power even when idle as long as the battery is plugged in. So I think I'm going to use the tether as a switch, and when the tender-loco tether is unplugged, the DC power is cut. Then I'll build a custom charging connector to plug into the 10-pin tether and charge from the connector. That way I'll never be able to charge the battery and forget to disconnect or switch off the BR board first.
