...up your starter from solar - and only once the LB is "full enough"
It's likely to be about as much effort sorting the wiring out as adding an AMT12-2 but that has the advantage of topping up from any source that charges the LB not just one of them.
To clarify the "could work" my suspicion...
Thanks Paul. Didnt realise that the Smartshunt gives more accurate feedback and more importantly starter battery status, although I need to read up and get my head around how that works. For now I have added it and plan to fit it across the LB negative out.
The Ablemail is already on my future...
...back on here that the commissioning of the new battery went well. Sod’s Law always has the final say.
Good news first though, the Ablemail AMT12-2 seems to be working okay. I had the headlights on for a few minutes and I got the green led come on and confirmed charging of the starter...
...leave the internal blinds in to keep the sun out, in winter we have a small oilfilled radiator set at 5 deg to keep the frost out. I have an AMT12 to keep the starter battery topped up. I don't run it between uses, IMHO this causes more harm than good, as unless you get the oil up to temp...
So I have a Sterling DC to DC B2B charger and have bought an AMT12-2 to keep the starter battery topped up (Leisure Battery topped up by separate solar).
Is it as simple as connecting the AMT12-2 to the connectors in the Sterling unit labelled 5, 4 and 3 or am I a clueless :rolleyes:
AMT
You should make sure that both batteries get a maintenance charge - ideally you have a decent multi stage charger on your EHU already for the leisure battery so just leave it hooked up - starter battery you can either fit something like the AMT-12 to trickle it from the maintained leisure...
I’ve never been too sure of the effectiveness of my Ablemail AMT12-2 either. It has been back for repair once as it was not charging. The BM2 does occasionally show a 0.03v charging blip but it does not keep my starter at a constant voltage when I’m not using the van and allows the stater to...
...works for you longer term in a bit.
Some mount a quick connect under the bonnet to make hook up easy, others fit something like the Ablemail AMT12-2 trickle charger as a more fit and forget (so long as you have your leisure battery maintained from EHU/Solar)
If you do mount a quick connect...
My Starter battery was replaced by the garage I bought the Van from but I discovered the muppets did not code the battery, so I did it. I like the concept of the AMC so will get one and see what happens. The Leisure Battery needs to earn its keep in the off season:)
That’s more or less what mine shows. I assumed that by setting the AMT12 to “smart alternator” it didn’t fully charge the starter battery.
This is mine just now
1. Personally, I would connect my solar to the LB side of the DC-DC & fit something like an Ablemail AMt-12 to keep the SB topped up. Plenty of folk use this method & it works well. Fitting the solar to the SB side might fool the DC-DC into thinking that the engine is running (Depending on...
IIRC, when I had the Sterling unit, you had to be pretty smart to press both buttons at the same time, it took a couple of goes to press them both simultaneously.
Sorry about the (non) English of my last post. Posted without reading it!
Do you have some sort of shunt for your BM2? How does it know what flows in and out of it?
Looks like a nice setup.
So what I would do.. would be to add in a Abelmail AMT12-2.
I've got one on both vans now and it works perfectly..... (I've also got the 230ah lithium, and 50A DC-DC etc etc on both vans.)
I've also added in the Abelmail Bluetooth adapter to twerk the AMT settings...
Nice one, thank you. The van is a daily driver so the only time it doesn't get driven is the weekends basically. Should have said, the panel is one of the suitcase ones so it's not permanently connected.
I like the idea of having all the data in one app and, as I said, I do trust the Victron...
Installed a AMT12-2 Trickle Charger between the Starter Battery and Leisure Battery.
Re- instated my newly sprayed (Gloss Black) overhead lighting unit.
I'd agree with the comments so far.
With charge rate I'd keep the Orion XS around 30A for general use, it's kinder on the battery, charger and keeps the heat down. You can always bump it up to the full 50A for a the week or two you're off grid and really drawing on the battery.
With the...
Good suggestion with the AMT12-2 @Dellmassive - Easily installed this tiny little thing today, (Hid it under the drivers seat with my Renogy 170Ah Lifepo4 and Victron 12-12/30 DC-DC charger.)
Waiting on the BM2 to come tomorrow, but once I managed to set the thing up for Smart...
