Hi,
I have come into possession of some batteries which were purchased to be used with a large UPS and were never used. Ive picked these up for a song and keen to know if I can use them in a dual battery setup behind a pirhana system.
They are Dynasty brand battery manufactured by
John Controls specifically for UPS's All 12V with 75A/hr ratings.
Does anyone know anything about them, ie is a UPS battery radically different from a normal deep cycle batery?
Pic of the top of the battery looks like this -> Piccy
The manufactuer doesnt have much on their website Website

Shouldn't be any reason whatsoever why you cant use these batteries with the Piranha Controller.
The battery(s) is 12 volt.
75A/hr Deep Cycle which gives you a reasonable capacity.
The Piranha Isolator allows batteries of different size and type to be used in conjunction with the starting battery.
Do you have an existing dual battery setup in your vehicle?
The only consideration you need to allow for is physical size.
Will they physically fit into the cradle?
If yes, GO FOR IT.

I've used UPS gel batteries which were designed for shelf use in a dual battery situation under the rear
seat in my troopy, they were 250mm square, 6v and two hooked together made a beaut auxilary battery, I had them fro 5 years and then sold the truck, probably still going
well.
anything free, you've lost nothing experimenting. Get a few and you can sit them on the shelf if the first ones fail.

These batteries are an AGM construction. You will find plenty of discussion re using AGM batteries as 2nd batteries both here & on the overlander
forum - Generally all good compared to a regular deep cycle battery. (My opinion there - don't flame me if you don't agree...)
I have installed 2 banks of 88Ah Dynasty batteries into my
camp trailer - lots of power for what I do. I use a reasonable charger that provides the following features: a soft start; boost charge at 14.4v then float charge at 13.8v. I connect this when I come back from a trip (or when near power) & leave it on till I move on. The float charge ensures I always have fully charged batteries when I head off & the batteries (out of a UPS) like the constant charge.
Like Peter said, give it a go - i did & am happy with the results.
