    Bob, I'm with you on the Aero Lithium Battery Co. The problem with their battery was that they had no overvoltage protection circuitry of any kind. Now days most all of the lithium batteries made for aircraft have this protection circuitry included, I have much more faith in them now since the Aero Lithium years. However, you can't go wrong with a good ole lead acid battery

    Post Re: Best Battery for our Carbon Cubs?

    I have read through many of the posts "Best Battery for Carbon Cubs" etc. Good stuff.....However I am looking for information with regard to Jump Starting a weak or Dead Battery?

    Eg. Extending two lower gauge cables from the installed 12 volt Batt's positive and Negative poles, forward under the seat(obviously with a system protecting each of the leads from contacting each other or contacting any other metal) then if needed using a small portable power bank jump starter to power the battery via the extended Batt cables, thereby the starter.

    Questions:

    •Has any one out there set up a system for doing so? PICTURES?
    •Since the portable Jump Starters have high Amp outputs any potential when hooking up/using portable jump starters of harming the other back up batteries to any of the G3X electrical systems or the Ignition for example?
    •Any one out there that has devised an en-genius way of installing a back up system and has actually used same please comment.
    •ALL THOUGHTS WELCOME

    Thank you , Slow fight

    Slow Flight,

    I have always used the standard Odyssey batteries that Cubcrafters uses myself. I also always install a battery tender/maintainer when installing the battery. I have a link below to an inexpensive one that I have used 4 times from Harbor Freight. It’s a SMART charger with setting for STANDARD use (for normal, daily charging/maintaining) and STORAGE mode for use when storing the battery for longer period. It charges at different rates depending on the status of the battery.

    https://www.harborfreight.com/4-amp-...ner-63350.html

    It comes with a lead with ring connectors on it so you can attach it permanently to the battery terminals and then just run the pigtail lead forward by the ELT (if installed there under the seat). I just leave a few inches sticking out the front there that I can access easily and plug it into the charger/maintainer each day after flying. The pigtail connector has a rubber plug that covers the connection (plus one is recessed anyway so no change of contact).

    I also always carry with me one of the jump starters. The link here is of an Armorall model that is about the size of a large cell phone. I just use this one because Hardrock casino was giving them out free one day! There are many models of these type jump starters out there. This one is nice because it holds it’s charge forever and is strong enough to start my truck Diesel engine!! Also, I take it hunting , etc and use it as a battery pack to recharge USB accessories while in the field (like cell phone, etc. Anything with a USB connector). They are lithium so I keep it in the plane but in a pocket within reach of my pilot seat in case of fire.

    To use it, you just remove the 2 pins in the back of the pilot seat, slide it full forward and then it will tip up forward exposing the battery. You can connect the jump starter easily.....drop the seat.......start the engine and then jump out and remove the jump starter. I’ve only had to use it once before I used the maintainers and it was a 15 degree day and I hadn’t started the engine in a couple weeks. Now using the maintainer, you should never have to use it but its so lightweight and compact......why not?

    Hope this helps.
