what is the internal resistance of one of these batteries?

Thank you for your question, the internal resistance is around 30-50 milliohms.

Can this be used to power a 12v winch

Thank you for your question, you need to check what is the working current of power a 12v winch, the working current of our 36Ah battery is 36A, if the current is less than or equal to 36A then you can use it.

Can 6 of these be hooked up in series? my ups has a 72v setup. i would like to use these batteries instead but can’t find specifics.

Thank you for your question, there is no substitute as our batteries can only be connected in series with a maximum of 4.

Can this be used with a Batcaddy golf cart?

Thank you for your question, yes, if you are using two or more batteries in series, it is recommended that you use a Lifepo4 charger to charge the batteries.
