Topic: Battery Boxes Posted: 04 Jul 2017 at 5:01pm |
I'm going to replace my one 12volt battery with two 6volts. I think the 6volts are larger than the 12 volt so I'm wondering if anyone knows off-hand if the battery rack that came standard on my 172 will accommodate the larger battery boxes or will I have to have it altered? I have to order the boxes so I don't know their dimensions. I'm going with Interstate batteries.
Thanks in advance.

You have 2 choices, two separate boxes, or a single end-to-end box that holds both. Either way, 2 6's fit.

I am not sure about the tray dimensions. Just measure the width, length. Height shouldn't be an issue.
Get two boxes that fit end to end, or one double box that holds two to save more space, also the double box is easier to wire. 6 volt batteries weigh about 62 pounds each. A 12 volt will weigh about 52 pounds each.

Drill holes in the bottom so they don't collect water. Also makes it easier for the wasps to get in......

The standard batteries (usually one or two 12V batteries) are size 24. The 6V batteries that people have been talking about on this list are size 24.
Figure out your battery capacity by calculating how many watt-hours (WH)each one is by multiplying the AH rating by the voltage. Then you can just add up WH regardless of voltage or configuration (series/parallel does not matter when you use WH). E.G. 6V * 225 AH = 1350 WH an equivalent capacity 12V battery would be about 112 AH (12V * 112 AH = 1344 WH) You want longer run times, get more WH.

Your arithmetic leaves out a critical factor. When using 6v batteries, you need 2 of them to make 12 volts. So, 12 X 225 = 2700 WH 2 group 24 12v batteries provide about 160 aH, 2 group 27 about 210 aH

Wasps are less likely to get in through the holes than they are through the openings where the wires pass. I have dual 6V batteries in separate cases. The lids have large openings. The holes I drilled are small. |

We run dual 6V batteries in our 179 and also have separate battery cases. The cases cost something like $10 apiece at Batteries + Bulbs, which is also where we bought the batteries.

So if you are using 6V batteries, you will need a minimum of 2. If you want to increase capacity with 6V batteries, you will have to do that in multiples of 2. That means 2, 4, 6, 8, and so on. If you are using 12V batteries, you can add in any increment, 1, 2, 3, 4, 5, and so on. The difference will be that regardless of how many 12V batteries you're using, they will be connected in parallel. The battery math stays the same. When you are comparing AH, you're not really looking at capacity unless you are also looking at voltage. That means watt-hours.
