can i charge more than one battery at a time with this controller?

Yes,, just be sure you have them hooked up correctly.. I have 2 -12 volt deep cycle batteries and 2 6 volt good cart batteries hooked up to my panels via the controller. The Sun force charger drew moisture and burned out. I replaced it with a Thunderbolt controller. It has a digital readout which is far superior to the simple/confusing light system on the Sun force controller. Also it was only $30-$5 shipping and I received it in 2 days.

Connected in parallel up to the rated voltage of the controller, you can charge more than one batteries. The maximum charging current is 30 Amps.

this controller doesn't care if it is 12 or 24 volts,, not very many watts though,, it will take a while to much charge in that battery

Yes, you can charge only 1 battery at a time. I do this often. I find that this charger works very well and I like it.

You can connect two of these to your battery but I don't recommend charging the battery and using the USB at the same time.

I don't know for 100%, but I'm pretty sure it will only do one at a time. If you stacked one on the other, the top device may be too far from the pad to charge.

This controller will handle up to 30amps. So for example, I have 3 panels at ~145w each (~7.5 amps) that are connected to each other and run to this controller. Since I'm only bringing in max around 22 amps, then this one controller is plenty. I could actually add one more panel to it of the same size as my current and it should continue to work fine. To answer your question though, yes, if your panels are large enough to put you over 30a with two panels, then run them side by side and connect the two controllers to the same battery bank without issue.

If you are moving the panel from boat to motor home, then no you don't a second charge controller. just transfer the entire unit to each battery.

This can control two 12v items but not individually. both items will be powered at the same time.

Yes, you can charge multiple size batteries at the same time. Think of this charger as 4 individual chargers in one.

I just called Deltran (the company that makes these) and they said it is not intended to charge more than one battery because the charging circuit will only detect the charge condition of the first battery it is connected to, and so any other battery connected in parallel may not get fully charged.

It will charge one at a time but it can charge pretty much any batteries you have. It works for all types and scales of batteries. Hope this helps.

Yes, You should put a charge controller in line to batteries, rated at the proper amps/watts so you don't overcharge batt.

Not sure I understand the question, but if you mean can it charge two batteries at the same time, the answer is no. That said, it charges quickly and it has not been a problem doing them one-at-a-time. Great charger!

Yes. I disconnect the battery from my camper 'load' during the day, allowing the battery to charge, then switch back to battery in the evening. Just requires in-line switch for 'load' side of controller to camper and in-line switch from battery to camper. Has been working quite well.

Yes, but the answer is not as simple as connecting the batteries in parallel. Because each battery has slightly different capacity and internal resistance, over time, you will get uneven charges between them. The charge controller will stop charging once one of the batteries gets full, leaving the other not-fully changed. The result is reduced capacity, that is, you will not get twice the capacity of individual battery. The solution is to insert battery balancer between controller and batteries.

Yes you can however you will need a controller capable of handling both panels. Most small inexpensive charge controllers handle 7 amps or less. Two 60 watt panels will produce more than 7 amps on a sunny day.

Yes, but beware, you probably want to charge more than just 1 battery, more like a small bank of batteries. For example, I have mine hooked up to a small bank of 8 SLA 12V batteries giving me about 1500 watts stored to power a 1200 W Inverter for appliances. It's like a solar powered battery pack so that I can work and have phone conversations in the most odd places (no generator noise in the background, just pure silence or nature noises, it's awesome). You'll want a decent charge controller (I bought a 10 Amp controller, which is overkill, but has the better charge-methods and pattern that I wanted). Good Luck!
