Errin sent me two converters free of charge. The first one I screwed up on (I didn't state I had the adjustable one), I told him that and he still sent me a second. Errin has been very responsive since he became away of my issues. If I look back on several years of purchases, I've had no better support from anyone on any item.
Add that to the fact that I don't know of any other adjustable voltage 100AMP charger, add in a manufacturer warranty on such a thing, and I think it's a winning combination.
I have verified 96 amp output at 14.7 volts with my victron. The adjustable unit is high voltage, and I have verified up to 15.6 volts on my unit. Both of the unit I have had were able to do this.
Likewise, I have ignored the warnings previously mentioned here about Hot restarts. I am not in the mood during a camping trip to forget this rule, and sometimes I may be using it as a power supply with surges from my Inverter. This unit has performed flawlessly so far.
When I have recommended this product to others, I have also been careful about what to recommend. Adjusting and fiddling with voltages is not for everyone, even if it's the closest one-size-fits-all solution to the myriad of battery choices and combinations.
I gave him the contact info and will be contacting Errin. I am thinking there was a mistake somewhere on these and are mislabeled somewhere. I am sure Errin will be able to get to the bottom of it.
Admittedly, I don't even know if there is a problem? I was just making note that this 100 appears to be identical top the one I'm sending back to Errin.
I can have him call, but I'm not sure this one won't produce the indicated amps.
It is a PMBC - Amazon link
To clarify - This unit is the PMBC ordered from Amazon. My link shows that, I just didn't type it right (the letters get my confused since they are so close).
I did not intent to lead anyone to the conclusion that was wrong because it did not have the adjuster/display, but that this one is just one without that optional item.
Also - like I said Errin has been great (he even interrupted a baseball game he was at to help me). I am posting this to clarify that what I thought was possibly a mislabeled product from Randy appears not to be. I do not know what the output issues are with this smaller unit, nor do I know if the one my uncle has does not produce what it's labeled to. So hopefully this clarifies that it is very possible Randy isn't just re-labeling stuff.
I have swapped the product with the one Errin sent, and all is well. The converter I received originally could not push more than 75amps. With the same wiring, I have now tested an output of 96 Amps on 40% depleated GC2s. I could only guess why, so therefore I am not going to.
I am trying to state facts as I see them. I hope none of my posts are taken as a bad review of Powermax. I am currently very happy, and I recommend the product.
Errin will be getting the smaller one back.
I do have yet another plot twist though. My uncle ordered a PBMC-100 from amazon, received one like the one Randy sold me but with no adjuster or display.
PMBC-100 from amazon
I haven't brought it over to my house yet to test the output. More to come on that one but it'll be a few weeks more than likely before I'll have time.
I believe anything that says Boondocker on it would be a Randy thing. I have already taken any future business (and hopefully a few others) elsewhere. I got my replacement from Errin. Randy did not even offer assistance at all and did not engage in any customer service. Errin, on the other hand, has been great!
I have been convinced this is a 75 amp model since I witnessed it on my Victron. I haven't done a battery test with this model yet, however, I know as a power supply it'll add close to 100amps back when I hit my 2000w Inverter with a heavy load. I just fixed up all the wiring with 3/0 for the interconnects and the new inverter, but haven't yet done the charger wiring yet (thats next). I am getting the rated output it seems with the current wiring.
I talked to Errin, he said it was a 100amp unit but there was some mix up on who was supplied what kind (OEM vs more industrial type). I'm supposed to contact him monday and he will swap me out.
So looks like Randy just has some units that aren't up to the task?
Anyhow, smketter, those were all good suggestions to insure all was working as designed. Randy just said "Roll with it." You and him should swap places, as since I didn't pay you for a product but yet you still pointed the right direction, I could only imagine the service I would get if I did pay you for something. Anyhow, I figured after dragging my 4 GC2 down by a measure 200amp hours then turning on my 800W inverter and running the microwave I should see more than 75.6amps off my shunt. I did not.
12" of #4 wire for the Charger and Inverter as well. Resting voltage was 12.19, although it wasn't true "resting voltage" as I had about .25 amps coming out constantly. I did not have my hydrometer camping, so no idea on that one.
So I got a hold of Randy today. Randy told me that due to the internal resistance of my 4 GC-2s I would never hit 100amps, and 75 amps would have been fine. He told me just to "roll with it and not worry about it."
I'm pretty sure if I can get 4 12v Walmart specials to take close to 85 amps, I should be able to push down 100amps into 4 Gc2s?
Besides, I'd love to "Roll with it" if I didn't spend extra money for a 100amp charger. I also have a real hard time believing that at 50% depleted GC2s internal resistance lines up exactly to 75amp.
I've tried to get a hold of someone at Powermax, but no luck yet. Admittedly, I've only called twice (no message) and left one email through there support form. I'll try again next week more seriously.
Now that I've spoke with him about this, I can't recommend Randy. I think he's a used car salesmen with some electronics talent. Randy has no intention of helping me get to the bottom of this. So, be warned and stay away.
I called Randy to ask if one was available, and he said he could get one and it was $20 more than the 75 amp adjustable. I checked my invoice and also the sticker on the unit, both say 100amp. I tried testing at home, but figured I just hadn't hit the batteries hard enough to see max output before I left on a trip.
Out on my trip, I definately got them low enough, and no matter what voltage there was no pushing more than 75-76 amps according to my Victron meter.
I've got 16" of 4 gauge wire and 4 brand new GC2s from Sams. Considering I could get 80amps from 2 Vectors hitting 4 12v Walmart GRP 27s under less depletion, I am sure I should have seen more.
I just left Randy a voicemail to see what he knows. Randy's always seemed to be good guy when I or anyone I've sent his way has dealt with him so now I will wait and see what he says.
My Powermax story goes like this.
Ordered a 100 amp adjustable voltage unit. The UNit which came had a 100 amp sticker right on it with 3 40 amp external ATC fuses.
Once it arrived, a pair of New and fully charged group 31 AGM batteries was taken down to 50% Via a 10 amp load for 10 hours.
The powermax, when attached, and cranked all the way up, was not capable of more than 75 amps.
Randy tried to tell me that 2 AGMs at 50% could not accept more than 75 amps. Effing BS!
Then measured the unit and Randy said yes that is the 100 amp version, bla bla bla, talk to Errin at powermax.
Errin said send it back, if it tests at 75 amps we will ship you a new one and refund the return shipping.
Over a month later a PM3 100 NON adjustable voltage model arrives. It has 4 40 amp external fuses and is an inch longer. It is never unboxed as there is no adjustable voltage.
Another month goes by and the adjustable voltage model arrives, also 4 40 amp external fuses, and an inch longer than the first '100 amp' model
It tests at 94 amps and line voltage is the suspected culprit for the 6 missing amps.
So my take is that Either Randy is unaware he is selling 75 amp models as 100 amp versions or is ignorant of it. Telling me that two depleted group 31s AGM's could not accept more than 75 amps infuriated me and made me lose all respect for him. Simple dishonesty or complete ignorance, one or the other, nothing else.
I would recommend skipping bestconverter.com entirely and placing any orders directly through Errin@powermax by phone. Screw the lying or ignorant middle man. All these adjustable voltage models are special order type things, not done by Randy, but by PowerMax.
My friend whose money was spent acquiring this Powermax tried to get an electronic timer installed for all the trouble along the acquisition of the correct product path, and they said they could not make it work properly.
I have a spring loaded 12 hour timer for the 94/100 amp adjustable voltage model.
The return Shipping was never reimbursed, and the automatic model still sits on my friend's bench next to the adjustable voltage model, so the drama is not quite sorted out yet. I am not sure if his card was charged twice, or if Powermax wrote off the non adjustable model.
So I would not order any Model without a means to test its maximum output on arrival. There is some dishonesty or ignorance going on with regards to what stickers are placed on what models.
If we had no Clamp on Ammeter we would have believed the 75 amp model was the 100 amp model like the sticker says.
I think I'm in the same boat. I ordered a PMBD-100 from Randy with the adjustable voltage. It arrived, has 3 fuses, and after camping this weekend found during a camping trip it wouldn't push over 75amps into nearly 4 brand new GC2 Golf cart batteries at 50% depleted. I have a Victron power meter to see amps in/out.
I did request by phone a 100amp model, and he said he would make one for me. I paid extra over the 75amp model.
To be fair I haven't called Randy, yet. I think I'll call and find out what the deal is. Did Errin say the 100amp model must have 4 Fuses vice the 3 on the original?
My bovine scatology sensor went to full alert the first time this guy posted.
I now wonder if perhaps this could be considered libel?
I know this guy personally, and while I am not an authority or a regular poster here all the time, I have been here for many years. Please trust when I say this is not fabricated in any way.
Libel would be if it was untrue. Ironically, My co-worker passed his trailer on the side of the highway (another fellow camper) and didn't realize it was the OP's. That Tuesday morning after our 3 day weekend, my co-worker mentioned it to me as if it was odd someone would abandon a nice trailer on the side of the highway right there. My co-worker was driving from Albuquerque to El Paso that weekend in a Hyundai Elantra - He left Friday and came back Sunday. This incident with the OP Thursday Night and he didn't get service until Tuesday. I'd hardly think the circumstances I just described warrants a pegged B.S. meter, he's just frustrated!
Moreover, the scenario I just described hardly calls for a bad weather policy being enforced.
Anyway, I vouch for the validity of the story and it comes with a money back guarantee!
