Error codes EE8 &amp; EE1 ??? I killed 2, using them on a small 30x30cm (12x12in) solar panel I use to trickle charge my car battery. Voc &lt; 30V

You'll melt it down if you hook it up in line you can only check a battery ..you cannot check running voltage

These are 12 volt 35ah batteries. (Volts x amps = watts) So 12vx35ah = 420 watts max capacity per battery and 840w for the pair. If you want your batteries to last, do not discharge below 50% -- Therefore, with (2) batteries at 420 watts each, there is a usable 420w if you want your batteries to last a reasonable amount of time (500 cycles) - Your application may already have a low voltage limiter which won't let you drain below 11.9-12 volts which is about 50%

If you plugged the voltage adapter into the wrong voltage, you could have burnt a circuit. Voltage must be compatible.

I have done that,but it breaks the warranty. If it has one, its fine though. I honestly think they work better on my solar batteries when I cut the wires and run them to it anyway.

Several possibilities for the problem. Use quality batteries such as Duricell and be sure to buy from a supplier with a high turn-over. Be very sure that the battery's are fresh. Even a dead battery will measure 1.5 volts but it will not be able to deliver the required current. When operating with low voltage, contact resistance is always a problem. To minimize this resistance issue, always spin the battery's after installation, this polishes the contacts. There is always the possibility that the unit is defective. I have not had any problems with my unit..............hope this helps.............Bill

hey Icepuck, did this work? Could you do same with a battery charger I am wondering? Im trying to run 12v lights off a generator and trying to find a solution... FF here too and rigging out a response trailer..

I got the same error when I tried using an ac adapter that was too small. I purchased the tenergy 12v adapter and it worked perfectly. I hope this helps.

I have 6 on a car battery with 14w solar panel to charge. Only failed when left on.

I did not have success with them, only temporarily. Due to higher voltage, 4.2 Volts, they have a regulator that cuts off when ever he wants and your flashlight will go dark, even do the voltage will read 3.2 on the voltmeter.I used them in a NOVA flashlight. Rechargeable batteries made 2 or more years ago with different technology worked fine, and their initial voltage after charging was 3.2 V. Honestly I don't know what are this batteries for, I will not risk an electronic devise with them. I am an electronics engineer. Sorry Tenergy.

Not sure, but they work with Voltaic's batteries. If the solar panel for the goal zero 21005 provides something like 18V when fully illuminated then it should work fine. Might need to make sure the that barrel jack is the right size.

I tested the voltage when batteries were very low and fully charged. My controller did what the specs said. Good luck

No idea, but I think it draws too much power for small wires. Connections may have corroded just enough for voltage drop.

Not a good idea to draw volts off one or two batteries. Use a voltage reducer.

I connected in series. Try this site for connecting info. (may have to cut and paste)http://www.solarrvpanels.com/index.php/wiring-rv-batteries-properly/

I've seen some discussions where there was a regulator required for use with solar chargers in some situations. Had the same issue with my lawn tractor; no charge after 8 hours in the sun. But it works fine for other batteries... go figure. May want to ask someone at your cycle shop about how to use this. And the other responders are right, if your battery is stone dead this thing isn't gonna help you. I found a 6A Stanley charger at Lowe's for $25 to use on the lawn tractor.

I would believe the instructions! Keep the + and - of the panels isolated from your trailer ground. The charge controller to batt should go directly to + and - terminals of batt ( + should go thru a 30A fuse! ).

I think I read somewhere they are not compatible. I know they work on gas or regular electric elements.
