Just a thought, if the aforementioned long bit of cable is offending, could an old-fashioned ignition coil do the same job? No. Are you sure?

This is an interesting site, obviously they are trying to sell stuff. octopusasia.com/charging-lfp-or-adding-a-alternator/It seams most of these fancy regulators need to talk to the batteries bms. This isn’t going to be possible on my valences. It looks like it might be the voltage drop diodes and long length of cable. It’s all a bit confusing. I need to use the equipment I already have eg valence batteries and 120amp lucas a127 clones. Yes this is a fundamental problem with Valences, the BMS is there but inaccessible as are the individual cells, and there is no switchery to provide the ultimate protection. However you could still consider an external alternator regulator because it maximises the alternator output whilst not overheating the alternator (ie one with a temperature sensor) and you can set the voltage to whatever. Just need to be careful that it isn’t one that supplements the existing regulator (because they can’t decrease voltage, only increase it) as opposed to replacing it.

How about a really big one?

Well, at least he answered your question. I feel cheated. I'm off to cry myself to sleep, and hope the tears don't damage my clown makeup too much. If you asked an unanswered question, I missed it. You’d better ask it again.

If you where in my position which regulator would you be looking at?

If you asked an unanswered question, I missed it. You’d better ask it again. It was to do with these tractor regulator things,and how to connect them. I was under the impression one of the wires can be connected to a resistor or potentiometer to alter its voltage,and the temp sensor used for a different purpose. However, Kris later said that the 3 he purchased had a fixed output of 13.7 V. So, I wonder if you can clarify how they work please,and how to connect them in place of the standard regulator fitted to the A127 type alternators. As its the next step in my install, I thought here would be a good place to ask. That may not have been my original question but it was along those lines. I feel no shame at all for hijacking kris's thread. Thanks. I don’t know because I’ve never tried it, but I would think you are correct in that the temperature sensor could be substituted for a resistor to reduce the regulated voltage. No experience of doing that though.

No experience of doing that though. OK cheers. Maybe a, question for the other place unless JohnV or peterboat happen to know. They don’t use alternators to charge there’s. But I think your right

Just need to be careful that it isn’t one that supplements the existing regulator (because they can’t decrease voltage, only increase it) as opposed to replacing it. If you where in my position which regulator would you be looking at? I had a look at the Sterling ones hoping they might be ok, as they can work as a replacement for the built in reg, but they don’t have a Li setting. You could use the American gel setting of 14.1v but that is rather high to hold a Li battery at and I’m not clear if/how it goes to float, I suspect it’s based on time and designed around LA. Adverc is just an add-on reg and can’t reduce the voltage of the original reg (which has to be left in. So that leave the Mastervolt Alpha Pro III. Without a Mastershunt (another £500 or so!) I’m not sure how clever it is, but it does have adjustable voltage settings (you need the PC interface though) and an optional alternator temperature sensor. This is the reg that Ed promotes, so he would be the best person to ask about it. All of which is why I built my own reg!

Not all of us have the time/ability to make our own. So we have to make do. But I did think by now that there would be something on the market. Oh there is the wake speed as well but that doesn’t seem to work with Lucas clones.

I’ve seen the circuit design before it went “professional”. I know my reg was designed amateurishly as well, but the core of my reg is a single chip reg that someone else designed and it does 90% of the work.

Amongst other things like product liability, because it’s designed for my specific needs, using data from my home made BMS (cell voltages and temperature) and BMV712 SoC data (also via the BMS). It wouldn’t work properly as a stand alone unit.
