    No dog in this fight, but that is not my experience. I keep one in my truck. Charged it when I got it. 6 months later, first mowing of the summer at the Clubhouse, the battery in the mower was dead. (Super Cub, I think 22 hp engine) It rolled that engine over just fine for about 30 seconds until it caught.
    I didn't recharge it.
    Working the hut, a truck died in the pumps outside. He killed the battery. I got my pack out and turned his truck over for about 20 seconds before it caught and started.
    I don't know the brand, but it has lithium power.

    Question: I have a cranking battery and 2 TM batteries in series, can I also parallel the 2 TM batteries back to one side of the selector switch to charge them from the motor? And if so, can I put the switch in the "both" position to charge all 3 at once?

    It is possible to rig up something that would do just that but I don't know of a commerical product that would do it. The reason is simple, your big motor would take too long to add a useful amount of charge to trolling motor batteries. The two battery systems are there to charge a house battery that runs rather low current devices like lights, radios, maybe even a short duty cycle windlass, but nothing even close to the energy needed to run a trolling motor for any length of time.

    TRUCK PAC
    I have bought several of the $100 jumpers and they never worked when I needed them, never.

    I was sick of it, and bought the $270 Truck Pac made for industrial/commercial use, liked the one review of a junkyard owner talking about jumping 40+ vehicles on one charge.

    I've had it for years now, it doesn't have a radio, doesn't inflate your tires, doesn't sing you a lullaby, it starts your vehicle immediately, always. It's unreal, tractor, truck, whatever, it doesn't take even 5 seconds of cranking, you hook it on, go turn the key immediately, and your vehicle is running strong.

    Honestly, just everything you could ask for, I charged it when I got it, it sat in my truck for 2-3 years, starting my truck and others vehicles several times, I then put it on a charger, was still charged very near full...

    Just works, just handed it to a guy about a week ago to use on what I believe was an old 80's/90 super duty, same thing, vehicle started immediately.
