Could two be hooked up in reverse to determine condition of battery bank determining amp in vs amp out? Good batteries having less of a difference.

Yes. My understanding, reading the instructions, is that it will tolerate reverse current. It just will not register the reverse amperage. So two wired in opposing each other would allow one to log incoming amps and the other to log outgoing amps.

You get the best indication of battery condition under load. All this tester does is provide a load and measure voltage. I expect it wold work fine for your deep cycle batteries.

i would get your battery tested at autozone or somewhere like that. also, are you sure your remote turn on wire is connected? i use the same amp with stock alternator and the car keeps up with it. it would be very unlikely to have a defective amp go through QC, but its a possibility.

leave them connected unless you feel there is a short, something drawing current, in the system. in older vehicles where there are no clocks or electronics you can remove the negative cable and put a 12 volt, pull fues test lamp with one lead on the negative battery post and the other on the cable , if it lights something is on, pull fuses until the light goes out

Yes, each at up to 5 amps. I have also charged 2s and 3s batteries at the same time, and 2s and nimh

No, It will isolate the two batteries so the load on one is not seen by the other. Both will charge he same. However the lower one will receive more charge current then the higher one until they are the same. It will not harm any batteries when connected correctly.

I would not recommend it, as the amplifiers may not draw power equally.... even if they are the same model, and the same manufacturer, no two amplifier's output will be 100% identical. Also, multiple amplifiers may cause the capacitor to drain it too quickly. If this occurs, the capacitor will not have enough time to to adequately recharge. If that happens, it will be as if you do not have a capacitor installed .... as the amplifier's power will be draining directly from the battery at that point (thus defeating the purpose of the capacitor).

Wouldn't hurt a thing. Battery fuses are rated for much higher current. The charger would have a different (Lower) current rating.

The amperage of the batteries do not have to match. however voltage does need to match.

The batteries may be wired together in either parallel or series configurations - depends on your needs.Parallel wiring = increased amp/hr rating at same voltageSeries wiring = increased voltage at same amp/hr rating

Output 500MA, if multiple devices were charged, item would not identify the device , and may also have bad influence to the battery

you must make sure that the voltage is right. the other battery must have the same info like 3.7 5000 mil amps li or same make. if in doubt don't use

yes, the 1 amp difference should not matter - it will actually make the battery less likely to fail, as it will be able to recharge more efficiently. My old battery was 4 amp, and this 5 amp replacement works like a charm.

Sure you can wire it to between battery and load. To monitor the amp hours your using.

the amp has two wires which attach to the battery, positive/negative. Be sure not to cross the wires. If you blow the fuse they are hard to find and you will have to buy them at your local radio shack.... I attached them directly to the battery and then used the remote on/off button for power. it is very easy to install.

I would assume that you could hook up two batteries in parallel (positive to positive and negative to negative) to maintain the same voltage but double the amp hours, but the better choice may be to just purchase a larger capacity battery in the first place. There are some very nice maintenance-free AGM batteries available on Amazon from Vmax. You could contact them for a recommendation.

Check polarity with a small DC voltmeter or multimeter. When the + (usually red) lead is connected to the positive side of the battery, the meter will register a voltage reading. If the leads are reversed, the needle will try to deflect backward.
