First one at the top (12V 7Ah).

Good deal?
Don't bother?
Avoid it like the plague..?

Hi Chris
Depends on the price and what you intend to use them for
Most people use these for a nitro starter in fact that what i use one for
Also do you have a charger capable of charging 12-volt sealed lead-acid or gel-cell batteries
If not you will need one of these as well

Take care dear friend

Negative Ghost Rider, that is not an approved approach!

Do a google search for a local vendor for a 12v SLA *sealed lead acid battery. There are many places that sell them nowdays. From wheelchair repair places, battery supply houses etc. Dont pay for the hobby lable, and pay 25% more for no reason.



I use this national chain for lots of batteries:

Thanks for the link, Nitro. I used to just to be able to simple plug in a power supply, but becaue our new field in on a landfill, it's going to be BYOP, at least until we can hopefully someday rig up some kind of power source. At the moment we can't even put up a shed, let alone pipe in electricity.

I have the Electrifly Field Box, and it holds two of those puppies, but I got mine from Batteries Plus. Much cheaper route to take.

Hi Andrew what type of vehicle do you have to transport your planes to the field The reason i ask, is because there are a couple of things you can do. if you have a tow hitch, you can make a small platform or buy one that will slide into the hitch, on the platform install 2 large battery boxes, get 2 group 27 Batteries and install them on the platform with the battery boxes, hook them up in Parallel, in the eng compartment, get a 80 amp continuous duty solenoid, and some 10 Gauge wire, run the 10 gauge wire from the vehicles battery to the Batteries at the rear of the vehicle, spice the N/C normally closed solenoid into the pos. red wire, hook the solenoids smaller coil wire to an ignition source, hot with key on, use a 50 amp circuit breaker in line too, while your driving you will be charging the Rear Batteries, when the vehicle is off, the rear batteries are isolated from the vehicles battery, to charge your planes with.
OR
get a trailer from Harbor freight tool, add your batteries to that, with a solar panel and regulator, you can even do the vehicle Charge wiring so the batteries are charged when your driving, with a plug to disconnect the chargeing wire. just my 2 cents worth, Take care, Chellie

Myself I just carry a Costco deep cycle "marine" battery wedged in the back seat foot well. I pull it out and recharge it at home when I need the space for a kid. Works fine.

thats works too and should be good for a couple of people to charge their batteries with Andrew was Talking a while back about having Charging power for the other fliers too, and i was trying to get him a cheap system so 4 or more of his rc fliers can charge their batteries at the field, and the batteries will be charged when he gets there from his vehicle and it will be a slip on, slip off unit, Elfwreck on the average, how many lipos can you charge with your marine battery before the charger will stop working Due to Low Voltage Take care, Chellie

Dang, thats a lot of battery It might charge up a few 1000mah 3 cell lipos dang you can run your house on those batteries with a big inverter I bought this battery desulfinator to try out, the military and Nasa use them, So I thought i would give it a try, Wow, It works Great, my sons friends battery in his truck was old and weak, so we hooked it up over night to the battery, in the morning he went to start his truck, and it felt like it had a brand new battery in it, I used it on my truck too, and what a difference, I am Sold on them, and it should help to make a lead acid battery last for 10 Years, thats great for my home solar system batteries I put some small Battery clamps on the ends, and works great, Take care, Chellie
