Ablemail AMT12 installation

[Dellmassive]

So you will have a bluetooth module going cheap then @Dellmassive ?

Ummm...

I think Ill have two AMT12-2 and one BT adapter.

Was going to sell on as a set.

But can consider splitting it up to help out a buddy.?

It's because the AMT12-2 has a LB cut off of 13.0v in the default setting, so when the LB starts getting low it'll stop using it to charge the SB.

However, as soon as there's any solar, that increases the voltage and it starts charging again.

On the other settings (the lithium settings) it only charges when the LB is over 13.5v so only when it's being charged by solar and never just using the LB.

That’s all true but it will also charge if there is a >0.3v (>1v on lithium setting) difference between SB and LB voltages and SB is below 12.1v. This stops when the SB gets to 11.5v (flat!). This means the AMT will sacrifice LB power to save the SB if it is getting critically low. Mine was working exactly like this when my old SB was on its way out.

Ah, ok - mines never gotten to that point, but good to know it'll do that!

This is good to know. I have no solar so was planning on getting an Ablemail to keep the SB topped up when camping off grid for a couple of days, which isn't often.
