Dear CubCrafters,
Many of us do not trust the PowerSonic 12V AGM battery as a viable solution for the ignition backup battery that comes standard from the factory or in kits for the EX-3/FX-3. There is a better option which I believe is used in the newer X/NX Cubs - the TCW IBBS LiFePO4 solution. A slim design that fits perfect in the space where the existing PowerSonic battery is installed.
As the TCW IBBS is not a trivial drop-in replacement I ask that CubCrafters provide a service bulletin or some instruction for those that may want to upgrade this battery to a better solution which CubCrafters already knows how to wire in as the ignition backup solution. You could sell a kit that includes the battery and new mount required to go in the place of the PowerSonic setup and instructions for what needs to be changed in the G3X config for the battery type change to LiFePO4.
The TCW IBBS 3AH is a perfect fit but another consideration would be the 6AH option that supplies power to both Light Speed ignition modules, if possible.
Upgrading to the TCW IBBS also eliminates the need for owners to remove the right forward panel at each condition inspection to replace the PowerSonic battery which only has a one year lifespan and some have found batteries failing at only two months after replacement. We cannot afford with our insurance to lose a plane over this, much less a life. You can do better, we can do better.
Please help us, your customers, be safer with more modern solutions for backup power.
