I've read these post and finally have to comment. I am errin ceo of powermax. Powermax did what know one else would do for you guys and built a custom unit. PD iota parallax and wfco didn't give you guys the time of day. Do we have it perfect no but at least we are trying. When we adjust these units with much higher voltages the amps will drop I hope you guys all know this. You guys are taking shots at us when you don't even understand the products your buying. No where in any literature does it say a pmbc comes with a meter or dial. A pmbc is made for bmw. If you just keep saying bad stuff about our product don't buy it. We have 40000 happy customers. If your reading this thread to try to determine what to buy these guys are pointing you in the wrong direction. Call me I'll explain to you what their not. If you are going to continue to just rip our product just don't buy it. To this day I have never got one of these units back. It's easy to come on here and complain and keep the product. It must be doing something right. My personal email and number are at the bottom call me if you want the truth. BTW randy is a great guy and if talked to with respect would help anyone with any issue

hmmm, so the pm4b's are a custom model? they run at 14.6 bulk, and 13.6vabs... not high voltage at all, when compared to other brand converters. and there is nothing in any of your outdated, inconsistent, inaccurate, literature that says the unit's current limit will decrease significantly (from 60a to 45a) at bulk voltage. so, now you're just insulting my intelligence... and you've now lost me as a customer, as well.

how many of those 40,000 even know what their converter is putting out? my guess is, most of them didn't even know where it was located before having to replace it. i talk to rv'ers all the time, and so far, almost every one of them knows squat about battery charging... how convenient.

all i know is i paid for 60a, and ended up with 45... and now i'm expected to pay shipping a third time??? because that's your policy????????????

i think i best leave it at that.

No the PM4bs are not a custom model, they are just Randy's version of the regular model (with 14.6v instead of 14.4v).

What he is trying to say, is that the non-adjustable units are the regular thing and he knows they drop their voltage once they hit the 14.4 or 14.6 or 14.8 depending on the model, and he knows some of us don't like that.

So, back when I was getting my prototype a couple years ago I was saying I wanted my charger to stay at the 14.8 once it got there for say, 4 hours before it dropped. So one thing led to another and he came up with the adjustable model that puts the voltage adjustment external instead of internal like the regular ones have it, and added the little voltmeter, etc. You have to order that special. THAT is the one he meant was made just for us picky forum guys.

Then after more badgering from us :) Randy started making his version of the adjustable one.( His goes to 15.5v not 16.5)

On the "Errin" adjustable ones such as the 100 amper, it has a watt limit, so if you crank up the voltage above 15.5 (goes to 16.5), it can't do 100 amps anymore. It will do about 80 amps at 16 volts or some such.

That would be quite an equalization doing 80 amps at 16v :) , so IMO this is a non-problem. My prototype only goes to 15.6v and I have seen 103 amps, no tapering, at 15.2v ok. :)

Meanwhile, ISTR way back your choices were:

- call Errin and get the whole 75 vs 45 thing solved and why wasn't the 75 a 60 anyway? thing, or

- open it up to be modified using the internal pot, which might make returning it out of the question.

The choice was made to do the mod.

I can understand about the shipping. When my Paramode broke the warranty deal was for me to pay to ship it to them for maybe $50 and if they agreed it was a warranty problem--my risk whether they would or not--they would pay me (how?)the shipping. I had been in it to crank up its internal pot, so I figured they would say that spoiled the warranty, so I wrote it off.
