I was torn between this and the 7 watt version, looking to charge and maintain batteries for a trolling motor, will this provide a charge at all?l

I use 3 of them for 15 watts total to recharge my 12 v camping battery every day

I have one on my trolling motor and my 40 hp Mercury Force and they keep my batteries up. No complaints here.

I have 4 of these chargers on different things. 1-farm tractor, 1-skidsteer, 1-dump truck, 1-dump trailer. They work great. Everything starts right up. Great cheap product.

Yes, this panal has the capacity to charge your batteries, just remember, the 20w is at optimal environmental conditions, sun, angle positioned ect...I always connect in parallel. You didn't mentioned the 'what' you are utilizing the batteries for...heavy watts out, need more watts in. Good luck!

I believe like one of the other responses here, the larger size (3 amp) will be better for use if you do not want to use it as a maintainer. I too have found the newer smart chargers do a better job charging even though they are not excessively high on amperage rating. I have actually been lucky enough to save older batteries by using these charges and allowing them to charge very slow over several days.

I have used this battery to power a similar trolling motor on a Native Watercraft Ultimate 16 with 2 adults for 2 consecutive days. I do not know how much power was left so I recharged before the third day. This was not constant use, but it was a significant amount of time running on speed levels 3 and 4 of a 5 speed motor. I have done this several times in both river and bay applications. Hope this helps.

I use this for the Hummingbird Fishfinder. This will not hold enough charge for the motor you have in mind. Smaller devices are what this battery was intended.

I am not sure if it would charge completely. This is more of a battery maintainer when used with the amperage reducer that came with mine.

May work for a little while. This battery is meant for smaller applications such as fish finders. A trolling motor needs more amperage, like a lawn mower or car battery.

i am sure it would but this unit really does not put out alot of power. i honestly dont even use mine anymore i use the plug in type battery tender that has multiple ports. i keep both my trucks and both of my harleys maintained with it i accidently left the lights on in my old truck and i could have easily jumped it but i wanted to see how long the solar charger would take to charge the battery full. by the end of week 1 nothing by the end of week 2 it would barely turn over that is when i gave up it might be good for just maintaining but if any of your batteries need charged i would not get the solar. i am sure it would but this unit really does not put out alot of power. i honestly dont even use mine anymore i use the plug in type battery tender that has multiple ports. i keep both my trucks and both of my harleys maintained with it i accidently left the lights on in my old truck and i could have easily jumped it but i wanted to see how long the solar charger would take to charge the battery full. by the end of week 1 nothing by the end of week 2 it would barely turn over that is when i gave up it might be good for just maintaining but if any of your batteries need charged i would not... » Read More i am sure it would but this unit really does not put out alot of power. i honestly dont even use mine anymore i use the plug in type battery tender that has multiple ports. i keep both my trucks and both of my harleys maintained with it i accidently left the lights on in my old truck and i could have easily jumped it but i wanted to see how long the solar charger would take to charge the battery full. by the end of week 1 nothing by the end of week 2 it would barely turn over that is when i gave up it might be good for just maintaining but if any of your batteries need charged i would not get the solar. « Show Less

It works fine charging and maintaining my 105 amp hour deep cycle trolling motor battery. With only 6 amps max charge rate, I believe that charging is easier (with less heat) on the almost 4 yr old battery, yet it is fully charged overnight.

If used for a small 12 volt battery, it will not over charge the battery in any way. It is ideally suited for a small battery.

No this would not work for even the smallest of electric trolling motors. Not enough stored energy.

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!

I would say probably not. I use it to keep up a very small deer feeder battery. I sure it doesn't produce enough watts for the larger battery.

I used this for charging a smaller battery, a motorcycle battery, and discharging into a power inverter for landscape lights at nights. If you are going to maintain the battery without loads then yes I would say. It only produces 10 watts.

I'm not an expert but I don't think this thing draws hardly any watts or amps etc. I lost my instruction booklet because half of the unit stopped working and MinnKota said it can't be fixed. I kept it to use as a trickle charger for cars, boats etc. I would think almost any generator would make this charger work. It' basically a trickle charger so it's gonna run your generator a long time to charge a battery a battery. You might want a more powerful charger depending on your use to shorten the generator run time..

Unfortunately it will not. It is designed to run deer feeders and I use it to run my fish finder and GPS unit on my kayak. It would not provide enough amps to run a troll motor and would run out of power almost immediately. It is designed more so for low amp uses as I cited above.

Watts are watts per hour. This will recharge 15 watts per hour under ideal conditions. If you are looking just to float charge your batteries- this will do it nicely. If you are looking for this unit to be your only charger- I doubt 15 watts will be enough. If you are expecting this to be your only charger: How may watts are you using per hour and how many watts per hour needed to recharge after a days work? Remember that chances are you will be attempting to recharge durning the night which means no solar power.
