off grid solar, house batteries for rv, camper, boat. If you've got 12 V devices you can run that directly from the battery without any inverter which is nice.
I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.

Lol. These were NEVER $1,055. These "sale" prices are ridiculous. Like it's still a good deal. I bought two of these at ~$300 each last year and love them, but please they need to stop saying they're marking it down 75%!

No. These are NOT starter batteries. That isn't how it works.

How did you get $15 discount while paying with PayPal?
I just see the $56 promo code discount during checkout with PayPal
The $15 discount would have been automatically added to your PayPal payment. It is limited to the Promotion quota of 3,467 rewards, so all must have been redeemed.

If you really want, drag a long 0 or 1 AWG into a spot that has room for the battery.
It does not have the CCA to start a car.

Would this be good to run a trolling motor on a canoe?

A very large canoe going very long distances! For a Canoe you might consider a 100ah. Whatever floats your boat.

Kinda, they're normally 500, 300 is considered a deal, but with tariffs it's been wonky.

Anything under 300 for this capacity should be considered a deal and at 230 it's the cheapest I've seen. I think the only way to get it cheaper would be second hand market or to steal it from someone's boat.

Wonder if you could use 4x in golf cart. 14kw @51.2v with extension cable to portable power station or 48v inverter.....
i would say no....
Maximum continuous discharge 200A
so 200Amp @ 48V = 9.6KW. so you will be running the BMS in the red zone will only take one hot day and you will pop those transistors in the battery.
