What voltage battery would I need to make this a portable unit? Looking at the Humminbird Portable battery for $44

12VDC. I use these in a water right box from Plano also available here on Amazon. Don't remember the info but it is orange and cheap. 12V 7AH Sealed Lead Acid (SLA) Battery for Piranha MAX 160 Fish Finder by Chrome Battery

as far as i know, i have twelve volts on my boat, i would assume it is the same for a portable, look at the specs in the manual it is usually there. if not call hummingbird customer service. They should have technicians on hand that can assist you.

All I can say about the power for the Hummingbird is that I have it connected to a 12 volt battery.If you go on the Hummingbird website and look for the specifications of the unit it will have the operating voltage.

I can't find any information on the 871b battery even when I Google the number. What do you use it in? Do you know the voltage or the physical size?

i run both the 7.4 volt 850 mah, as well as a 7.4 volt 2000 mah on mine. i just leave the 850 mah inside the copter and then mounted the 2000 mah underneath the copter.

I use this panel to charge a 4ah lithium iron phosphate battery w/ a charge controller to regulate voltage(14.1). I wanted an unbreakable portable panel for charging electronic devices. You could link two of these in parallel to 2 group 24 batteries but it would only be a trickle charge(<20watts). I would suggest a cheap charge controller even though it's not necessary to extend your battery life. These are nice panels but for two 85ah batteries you might aim for 50-75watts.

I put a Gopro on mine so it added a little bit more weight. Its also above 105 degrees in Phoenix when I fly and I still get over 10 mins. I have an alarm that goes off when my batts hit 3.7 volts. I would highly recommend buying one. They are inexpensive. I usually get worried about battery life and land it way before pushing it to limit. I don't want it to have it auto land in a far off location and not be able to retrieve. I have a couple of spare batteries so its no big deal to swap them out. A flight lasts long enough so don't worry about it. 10 mins is a longer than you think. Just have some spares and enjoy. It nice to land and take a break anyway. You will love your FC40.

This would work, but 1 12v deep cycle marine battery will not last very long. I use this with a bank of 4 marine batteries at 220ah each in my bus and it is good enough for about 12 hours using lights, TV, Radio, and mini fridge. Most people use 6v golf cart batteries. You can wire 2 together in series to make 12v, and then you can wire sets of 2 in parralell to increase amp hours (how long they last. The other thing to consider is a means of charging the battery when not in use. If you are using a single battery, a 6 amp "smart" multi-stage charger should be fine. I use a 45amp-maxx 4 stage smart charger from Go Power. Works great! This would work, but 1 12v deep cycle marine battery will not last very long.

As long as you are sure it requires a 12 volt battery then all you would need is as follows: this exact battery, 2 spade connectors, and i chose the Battery Tender Plus for the charger. Next cut the stock charge port off the Hummer, strip the wires, crimp on the spade connectors and then plug into the battery. Mine arrived charged and ready to go! Works wonderfully! Good luck to you.

It requires a power source. You can use a BEC, or a (4) cell NiMH or NiCad battery (4.8v-6v)

That should work with no problem. I use mine to power a portable battery pack. Bought unit a few months ago and seems to work fine. I really like the case it came it, keeps everything nicely organized and convenient to store.

yes you can make it work but you would have to mount a transducer and carry a battery a much better choice would be a Humminbird Fishing Buddy its all self contained and portable see link. http://www.humminbird.com/Products/110-Fishin-Buddy/

it plugs into a 110v outlet, so I would be curious if a portable battery can provide that much power.

Totally agreed!!! so I'm planning to buy the spare battery...I think Amazon needs to correct the misleading information regarding the specification of UL30A!!

I just picked up a battery at my local fleet farm. The key is to ensure that you get a marine battery since it is going to be subjected to constant trickle charging and full discharge situations. Typically any marine battery will work as the system only needs 12volts to run on. They had a "Resolute MDC24" marine battery on sale, that stated you might be able to find one cheaper through Amazon Prime.

Are you installing the unit in a boat or kayak? I installed mine in a kayak and used a compact 12 volt battery, it works great and the Elite unit is outstanding for my application.

This cb is not a portable unit. It must be wired to the batteries of what ever vehicle you put it in. It takes no separate batteries.

This battery is a simple 12VDC power source. It will power any FFinder , stereo, LED light, or anything else that required this voltage. It does have a low amp/hour rating, so it would not power a larger unit with a lot of bells/whistles for too long. It works great for low- mid priced locators - $75 - 200 range, for example.

This requires an external 12v power supply which isn't included. A decent supply can be found on Amazon by searching for B007TGO3HO. It's about $7.79 and should have plenty of capacity for your project. Happy automating :-)
