rynicolson Posted May 30, 2020 Share Posted May 30, 2020 I upgraded from a big Banner to a small Odyssey - and bought an alloy bracket to fit forward of the ECU on the LHS foot well top side - where the standard CC banner would normally sit. However the new bracket whilst fits - is snug under the chassis rails and engine bay diagonal - also once fitted it does not allow the battery removal due to the "lip" around the bracket (yes I can cut / grind this off). I would be interested to know how and how others have installed such a bracket. thanks Richard Link to comment Share on other sites More sharing options...
SM25T Posted May 30, 2020 Share Posted May 30, 2020 Does that stop the battery sliding out under braking or impact ? If you can undo fasteners to remove the battery ... it's only every few years ? Link to comment Share on other sites More sharing options...
brianjhall31 Posted May 30, 2020 Share Posted May 30, 2020 I just did the same upgrade. After much deliberation I decided to move the battery from the original position over the passenger footwell to, where it is fitted on later cars, on the scuttle in front of the heater. My reasons were 2 fold; 1) the diagonal chassis tubes meant I would have to create another level above the footwell as there is not enough space to mount horizontally without moving ECU and ambient pressure sensor, 2) I was concerned by the proximity of the exhaust causing overtemp.On my car the existing loom had enough "latitude" to allow simply cutting some of the cable ties and re-routing. I then created mounting brackets out of allow L section and a thin alloy plate for the Box I bought on eBay. I also created a simple clamping device from the L section alloy to secure the battery in position after sliding into the box. Bolted onto scuttle using large "penny" washers on the underside to distribute the stress loads.Attached picture shows finished article in place.

Leadership Team SLR No.77 Posted May 30, 2020 Leadership Team Share Posted May 30, 2020 Richard, I was faced with the same issue with my bigger 680 size so I decided to fit the alloy case upside down effectively as a new battery tray. I had to use some alloy box spacers to raise the tray above the chassis diagonal but if you have the smaller size it's probably not needed. I trimmed off most of the flange, it's not needed now it's a tray, but retained a small section on each side to fit a diagonal securing brace. The battery now drops in easily from above and is SOLID!!Stu. Link to comment Share on other sites More sharing options...
brianjhall31 Posted May 31, 2020 Share Posted May 31, 2020 Not a bit warm down there for those big copper wires Stu? You can probably see I based my design on aircraft structural testing specs, maybe a bit over the top and heavier than necessary but its me thats mounted just behind it!

rynicolson Posted June 2, 2020 Author Share Posted June 2, 2020 Thanks guys. I’m reluctant to relocate in front of heater for a number of reasons (Angus Davidson for one who is currently building my model)... Stu might follow your route. I was about to build a ,’secondary’ battery box floor to ease removal and fitting but your route does this - you don’t have a pic of the box spacers you are using do you?

Curly Posted June 2, 2020 Share Posted June 2, 2020 Just fitted a PC680 vertically in "normal" place on shelf down from/in front of ecu.Have re shaped/adapted the standard banner tray/clamp - seem solid with some additional rivets fitted in same place . Haven't tested as need some longer cables - anyone know the rating of the cables? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted June 2, 2020 Leadership Team Share Posted June 2, 2020 Richard, I might need to take a couple of photos for you, not sure I have any currently.Also, be careful fitting a PC680 vertically, they're a fair weight so be sure if you have a front end bump the battery will stay where it is ....

Leadership Team SLR No.77 Posted June 2, 2020 Leadership Team Share Posted June 2, 2020 Some of B&Q's finest aluminium channel, I think 15mm, plus a few rivnuts and bolts ... Link to comment Share on other sites More sharing options...
rynicolson Posted June 3, 2020 Author Share Posted June 3, 2020 thanks Stu, fortunately my local marine fabricator who is excellent crafting special pieces for me on yachts recently bought a Caterham - we now get little marine work when I'm there as a result - might get him to build be a "single" piece channel along the same concept. Thanks again. Richard Link to comment Share on other sites More sharing options...
brianjhall31 Posted June 5, 2020 Share Posted June 5, 2020 Just to clarify (as my photo does not show it) I also have a 38mm L angle running the full width at the back of the box which is secure with bolts and doubler washers to the scuttle. Theory based on current EASA test spec of 9.0G forward case load means 7kg x 9 = 63kg with no permanent movement or deformation/returns to original position.
