Trojan Golf Buggy Batteries (1 Viewer)

[arthur49]

Clive Mott Gotobed recommends 2 x 6v batteries connected in series as being superior to two 12v connected in parallel and I aim to do this.
Has anyone actually done it as venting of gasses seems to be a stumbling block. There is no facility to attach a vent tube meaning, presumably, batteries need to be installed in a box/cupboard, and that is vented?
Does the box/cupboard need to be airtight apart from a vent at bottom?
Charger is 25A three stage so should be perfectly capable of charging 2 x 6v connected in series?
Incidentally, I trust Clive's expertise totally, but why are these batteries a better option?

I have 2 X 6volt Yuasa batteries on my VW and they work fine. Far better than the 110 amp 12 volt. They are much heavier than equivalent 12 volt batteries and are vented through the floor with plastic pipes silicon ed in.

12v traction monoblocs are freely available from Trojan and others, the 6 volt solution is no different in performance Ah for Ah, it might be just that they fit the hole better!

I have never understood the logic of 2 x 6v over 1 x 12v? Other than weight.
I have 2 x 12v 250AH batteries that weight 76KG each..... Those I could have done with splitting in half cause they killed my back lifting them in

Need you guys to help me out with a few questions.

1) Is there any advantage to using two 6 volt deep cycle batteries in series over two 12 volt deep cycle batteries in parallel in a RV application, and if so what are they.

2) Besides the number of cells what is difference in construction of a 6 volt golf cart battery like a T-105 and a 12 volt deep cycle battery. Of course in both cases I'm referring to Trojan batteries. (is there any other)

Thanks Sam Langford

The answer

Hello Sam:

The main advantage of using two 6 volt batteries connected in series is long life. They generally last about two times longer than 12 volt batteries. This is because 6 volt batteries have bigger and thicker plates that can better withstand the effects of deep cycling.

The main advantage of using two 12 volt batteries connected in parallel is backup. If one battery goes down, you will have the other battery to keep your system running. With two 6 volts, if one goes down then your entire 12 volt system is down.

In terms of capacity, if you get a couple of really good 12 volt, group 27 or higher, batteries then the runtime that you'll get out of the two systems is roughly the same.

If you need further assistance, please contact me.

We have 2 x 6v trojan batteries , in a sealed container , vented outside. They are brilliant. Weve got an 85watt solar panel fixed to the roof also. We go days with the tv and all the other electric gadgets that we and 3 teenagers have in tow , without needing hook-up.
Infact this weekend is the first time this year that we have needed the Webasto deisal heating on. Low , granted , but it was needed.They cope perfectly with that too. Normal leisure batteries were useless with it as the start up and fan drained them in no time.

We use 'Dyno' traction batteries with a Sterling B2B charger with excellent results. Although an open unit, they do feature condensing cambers on the caps, just like 'maintenance free' batteries and so far, topping up has been barely called for.
We bought ours from a local forklift battery specialist.
Other makes worth googling would be Hawker, CMP.
As a guide, we have 2x 115AH Dyno monoblocs and these will run our van for three days straight at well below 0 degrees. This is with the Webasto Dualtop running 24/7 and no rationing of lights and telly! Well worth considering if you have a skiing trip!

Thank you for all input. Incidentally, one reason for considering Trojan 6v batteries is space available. Ah for Ah, because of increased height of 6v batteries, they will fit whereas 12v will not!

Banner Energy Bull 180Ah battery

I considered golf buggy batteries in this thread but after deliberating I thought I'd go for Energy Bull 180Ah as it will just fit.............I think!

Spoke to Tayna before ordering re venting provision ........"none". Phoned Banner UK this morning "battery is centrally vented" What happens to the hydrogen gas given off during charging I asked "Don't know" was the answer but she went to ask.............Answer "could stick a vent tube into the side corrugation if I wanted........."

Its not going to be easy to create a 'box' round battery which I could vent........or am I unduly concerned re venting? (Battery facility is behind drivers seat. Existing factory fitted Numax CXV27MF100Ah Sealed Leisure Battery is not enclosed completely nor is there venting through floor!)

My conclusion - manufacturers, suppliers (and converters) play down the need for venting to an unsafe level. Energy Bull is not 'sealed' or 'maintenance free'.

We have x2 6 volt batteries(Rolls/Surrette) and they have been wonderful so far, we have just wildcamped for 2 weeks with no leccy admittedly we do have 280w of solar.

They are in an outside locker so no venting issues although had them inside in the previous MH,( i bought some plumbing elbow pipe from B&Q and they fit nicely on the vent caps)
