Just installed one of these new DC-DC chargers on my camper 300Ah lifepo4 tongue battery. Great specs, seems really solid and IP67 weather protected so it's fine outside. I'm very happy with it. Software app via Bluetooth access on my phone is appreciated. I was very pleased to find I can...

Still got it for sale?

I almost built one but had no time for that project. Since you mentioned EG4, I've got one of each: Lifepower and the EG4-LL. Both are 24v and run great but the Lifepower had some trouble with rapid high amperage discharge and would shut down only in one situation, when cranking up my camper's...

Look at Morningstar. Great controller.

For what it is worth, the firmware upgrade did prevent the total shutdown of my EG4 Lifepower4 battery when starting the air conditioner. But it still would not start it on that Lifepower4 battery. I swapped in my EG4-LL, which is practically the same battery with a different BMS, and starts...

I understand you think I haven't thought a move beyond the immediate, and that a superior chess player (which I'm obviously not) could look ahead and see what is faulty with my system. But while it seems to be obvious to you, I'm not aware, technically, what is wrong? Instead of educating about...

Appreciate what you're saying regarding capacity and space to store batteries. In my case, I already had the lead in my cabin's garage and some space for a bit of Lifepo4 was not hard to come by. I suppose if I were trying to increase capacity all within the same space it would not fit, adding...

Now that is a reasonable statement that you don't see any advantages and you perceive some disadvantages, namely a loss of high capacity, continued weight of lead, watering and maintenance of lead, and Puekert effect concerns. In my experience, first, as I perhaps did not explain well enough...

Here is an interesting 2016 academic article modeling the hybrid LFP and LA battery in a remote medical clinic: https://juser.fz-juelich.de/record/829025/files/PE_070_Christiane.pdf Here is a commercial product combining chemistries...

So, I think we all know what the Puekert effect is, and I'm going to assume you meant that in a joking manner. But your statement simply begs the question. I'm waiting for your explanation as to how this manifests as problematic in a mixed system. Can you please enlighten us?

What about the Peukert effect and what about active balancers? Not understanding what you mean with those references.

So, I updated the firmware on my 24v EG4 Lifepower4 and tried to power my 12,000 btu portable air conditioner in my camper. When the compressor started, the EG4 battery voltage apparently dropped, resetting my 3,000 watt Giandel inverter via it's LVD. The battery came back up then instead of...

Gotcha.
