CAMS In-Vehicle Battery Mounting Requirements

[WhiteDC2]

After a search on the somewhat frustrating online CAMS manual I haven't been able to find a lot of information on the requirements for mounting a dry cell battery within a vehicle for CAMS Speed events.

Does a dry cell battery have to be mounted in a box if the battery is to be located in the same compartment as the driver? Are there any other particular requirements, such as mounting, fusable links, kill switches etc etc.

Cheers

i'm checking out here for you:

we'll see if they have any idea...

kill switch is for "RACE" and above, not speed, but here it is:

Each automobile of the 2nd and 3rd Category shall be equipped with a battery isolation (master) switch which
isolates the battery and stops the engine. It shall be capable of being operated by the driver in his normal
seated position. There must be a second switch, or a remote means of operating the main switch, from the
vicinity of the base of the A pillar on the driver’s side or, for an automobile with no A pillar, in a comparable
position. This external device shall be clearly marked by a symbol showing a red spark in a white-edged blue
triangle of minimum edge length 150mm.

what i reckon is that you can put it anywhere aws long as it is sealed...

when i did my 83 Prelude - i got it fully engineered with the battery (Oydessy 800) in the cabin, it was sealed - so no worries...

the rule was that it must be able to withstand 20 newtons of force or something similar... i used some serious steel square bar to hold it down...

oh, and it was fused "less than 100mm" from the battery positive terminal.

i had a 50A fuse, but a DC2 might need a 100A fuse...

and heck - i jsut found this!!!

totally not battery related, but given me a few things to do before next season!!!!

uh-huh - here is some certainty on the battery:

Yeah the kill switch is only required in superspints if the car has a log book, I'm putting one in anyway since I'm going to the trouble of running cable through the cabin.

When you say "sealed" are you referring to the battery or the box the battery was in? Or didn't you have a box at all? I'm looking at running an Odessey 680 battery and if there's no requirement for it to be in a box for that style of battery, I'm not going to worry about it. I was looking at this to hold it down (or something similar if I decide to fabricate it myself) http://passwordjdm.com/PasswordJDM-B...P2131C457.aspx

Troy, are you re-locating to the cabin or boot?

I think he means sealed, as in covered/in a box.

[tinkerbell]

no - a 'sealed' battery is a "dry" battery... not a battery that has any actual liquid in it - like traditional batteries...

i had no box at all, i used 20mm steel square tube to hold it down with soem threaded 8mm rod... all insulated of course, and regret taking no pictures

examples of "dry" batteries are:

Fabricate something like this....

nah - 'sealed in a box' - needs to be "vented" to outside hte cabin to be engineered

that is a pain in the ass...

Hope this helps;

Except if the cables, lines and electrical equipment such as battery, fuel pump etc, are in compliance with the
requirements of the aircraft industry as regards their location, material and connections, they must be placed
or fitted in such a way that any leakage cannot result in:
• accumulation of liquid;
• entry of liquid into the cockpit;
• contact between liquid and any electrical line or equipment.

Should the cables, lines or electrical equipment pass through or be fitted in the cockpit, they must be fully enclosed in a cover of a liquid-tight and fireproof material. No oil, fuel or electrical lines shall be situated
beyond 600mm on either side of the car’s centreline and must not run adjacent to the main fuel cells or within
the crushable structure.

Fire-proof is the key word I'd say

[tinkerbell]

yeah, that is actually for single seater race cars designed exclusively for races and speed events...

not "normal" cars...

but i guess it is a good guide...

I'm relocating the battery to the rear left corner of the DC2. The general consensus seems that even though there may not be a requirement for a box due to the sealed nature of odyssey/optima/deka style batteries, there still needs to be sufficient protection from short circuit.
