Will this charge my 12V, 7AH, gel battery in 8 hours? I will be using a Futurlec charge controller. At night the battery will run a 4W LED. Thanks.

The max current in bright direct sunlight is about 1.5 amps, so it should on ideal days. I use it to charge my 20ah battery pack...takes a few days as I usually don't have it in ideal spots.

A very yes, but do not get in a hurry. Also make sure your battery is not so out of date, and a build up of sulfate. This is a smart charger, and the LED says no, do not do it! Also, note that a cranking battery that is often deep discharged or not used on a regular basis will die before it's time. WA4MUC

We are using these batteries to power LED lights in a semi trailer, being used to haul Marching Band equipment to competitions and football games. We have very bright LED lights installed (3 strips that consume about 11amps each, and 4 floods that consume another 10 amp hours. With all that, I can theoretically keep all the lights on for about 12 hours. I have not tested this to failure, but have kept all the lights on for roughly 5 hours, with no issues. We have a solar panel that charges the batteries all week (between band and football events), and then we use them on Friday and Saturday events, so far so good! Brent Jensen

2 hours with all 48 LED's is about the max depending on the amount of sunlight it gets between uses, it takes a full day of full sun exposure to fully charge so anything less then that will shorten the duration

That's definitely not normal. You should have a full charge after a few hours if plugged into 120V wall outlet. Either bad LED's or it's not charging properly.

We will never get a clear answer on that question. Too many variables. This little gen is only going to be able to get about a 25% charge in a couple of hours. This runs my 25amp house charger with 2 type 34dc batteries and I get a good "top em off affect". Batteries need 8 plus hours of low amp charging to get the last 25% of charge. I'm not sure if this will help but I tried. I feel this little gen is an easy insurance policy to keep the heat and lights going on multi day stays. I wouldn't use the dc charger on the gen unless my converter charger failed to operate.

I would imagine you will hit the limitations of the battery no matter how much sun it received the day before. I remember seeing my light work as late as 4 AM. You may need to go with a wired solution for anything better.

Dan is pretty much correct in the time it takes to charge with the stock USB charger. But for the RUN time, it depends on how aggressively/conservatively it's flown. I tend to get between 5 and 8 minutes of flight time before the LEDs blink to warn of low battery voltage and the impending LVC. If you upgrade the transmitter to a spare X4 (version 2) transmitter (see my answer to the 2.4GHz interference and novice flying question), you'll have the ability to switch the LEDs off (and on again) to extend flight time even more (at the expense of being able to maintain orientation in all but the brightest of flight environments, since this vehicle is so small).

Explain More.. I mean this is the best one I am using . You have to charge it in straight sunlight because it has solar cells . The straight dunlight should be must for 3 to 4 hours so it can charge properly. Right Now I am having 24 count of this solar lights

The label says 1W. I plugged one into a kill-a-watt meter and it shows .02 Amp. (20Ma). Problem is it show this regardless of the switch setting or whether the LED's are on or off.... This unis has not been plugged in so the battery may be charging. I will leave it plugged in and update this info after the battery has had time to fully charge.

I use two of these in parallel to charge a Marine deep cycle battery. With a 20-amp charge controller this setup works great for my location, providing about 10-hours of lighting on nights after sunny days, less on overcast days.

This is a rough guess but, 6x35ah is 210 total Ah, and if you have 100w panel/ 12v it's about ~8 amp max. But I find mine realistically charges about 5 amp hrs per hr. So 210ah/5amp is 42hrs of charge time. so you prob have 7-9 hrs in day of good charge, so 42/~8 is at minimal 4 panels... I live in midwest and have less sunlight per day. But I think 4 is about minimal. I work more with electrical consumption than I do with battery charging so someone else might have better charging math, but I am familiar with electrical systems. Hope this helps and sorry for all the math, just wanted to back my answer. Good luck.

On my charger (VP130 Duo-charger), the LEDs always goes solid red whenever a battery (regular or Gold) is plugged in. I have to remember to remove the battery(s) after one hour for a refresh or three hours for a maximum charge so that they don't get over-charged. I am not familiar with your charger.

I think that it's the output from the battery rather than the chemistry. I used li-MH rechargables, with an output right at 1.3v. You might be ok at 1.4, but you're right on the edge at that point. Also, pay attention to the color change rate. One of the RGB leds being offered is a nice slow rate, and the other FLASHES

You are mixing watt hours with milli amp hours in your question. If the battery is made for the product it should work okay. The current rating of the battery is not very critical. If the new battery is of a higher current rating it will take a bit longer to charge.

Probably not. Your battery pack is giving you 10 watts peak, Your charger needs 9.6 watts. This requires the converter to be 96% efficient. It probably can't make this. Do you know if your 12v device really does need a full 0.8A? Is is that just the max rating of the charger you are trying to replace?

Well these lights are 130 watts So off of a normal duall purpose battery with 200 amps will run for 15 hours. So if you run the other ones which I don't know the wattage of you will most definitely get 3 hours.
