They couldn't resist. They had to take a perfectly viable design and screw it up. This thing couldn't charge a battery correctly if the President of Harbor Freight's life depended on it.
After opening it up and tweaking, it just is not worth playing with.
The 59.00 dollar adjustable MeanWell 33-amp power supply that NinerBikes is now enjoying makes the thought of blowing money on the new HF charger frightening.
Not to worry. I have found a PERFECT MeanWell 5-amp power supply with a 16.0 volt regulated output that merely needs a timer, power cord, cables and clamps for equalization.
22 Thumbs Down on the HF garbage. Sorry.
I would like to add a "caveat emptor" to Mexi's post above. If you do go the MeanWell 33 amp power supply route... please, please, please... you had better be very, very well versed on battery recharging procedures, voltage requirements for your particular battery set up, time requirements, and baby sitting techniques and timing. On the surface, it sounds good, but it is a Power Supply Device, first and foremost... it was never engineered as a charging device... which means that you HAVE to do the engineering on it for voltage and timing, for your particular application.... you can, and will roast batteries if you don't do the engineeering calcs, volts and timing setup.
I use mine for one thing... 50% to 80 or 90% state of charge on one Trojan T1275, first thing in the morning. Baby sitting it, until I get a manual mechanical 2 hour timer... for my application, Boondocking and dry camping only... no power pedestal, ever. The stock POS WFCO gets used for those rare occasions.
I can really drag down an Eu1000i with 33 amps at start up at 15.0V... so a minor drop in start up charging voltage to 14.4 to start for 15 minutes, then getting 15.0V out of it for the next 45 to 75 minutes, and shut things off... and let my 120W solar panel handle the rest of the top off duties.
You must do your homework, before you go this route, and have some serious experience with battery charging... I take zero responsibility for your applications and your results.
You need to know the amp hours out of your battery, and the state of charge % wise to set the timer for what you need to put back into your batteries, to set the timer properly... and possibly isolate your batteries while charging from the rest your your electrical system while charging...
This is not a "set it and forget it" package, unless your daily routine is consistent, day in and day out, with some seasonal variations taken into account, and temps also. Cold temps take more voltage, hot temps less, to the battery.
