Traction batteries

[solarman216]

Hi all, I am just about to spend £1600.00 on a new set of batteries for our electricity supply, I am wondering if there are any battery suppliers in our midst I am looking at 6PZS-ET 840 2 VOLT Cells each weighing 47kg and 12 number to make a 24 volt bank, each cell is £138.12 including vat but not delivery, this is the best deal I can find, unless anyone can do better, regards Rick

In all seriousness it might be worth you ringing a specialist, what's the age of your batteries? As technology might have progressed somewhat since those batteries came out just a thought, would be a shame to spend 1600 quid when something better and superior is possibly out there

my current set is 10 years old, at 80% discharge they have a 2500 cycle life which is about 6.8 years but we do not discharge to that % but much less so that is why now even at 10 years use we still have 50% capacity, but that is getting tight if we want to go away for a few days, as we still need to maintain security cameras, fridge/freezer etc, so even when we are not here there is a 50ah drain and as only 220/250 available only gives us 4 or so days, now if the sun shines then that extends this tremendously but cannot be relied upon, so this new lot will give us nearly 700ah in reserve, and yes these suppliers are specialist battery people, yes there is better technology available, it is gell cells but at over double the price for only about 25% extra life it is not viable, just thought that as we have a very varied lot on here that we may have had a battery supplier or a person that works for one that could have got a discount, but at the end of the day I am very happy with the price, been searching a lot and do not think I can better it, and to be fair ten years ago I paid the same for a lesser amp hour battery, Rick

Well, from what you've just said I think your on to a winner

I don't know nearly enough about the field but If these guys are specialists then you've gotta out your trust in them I guess.

And on a plus more power for less buck has to be a good thing too
