Hello everybody...
I have now considered for a long time where I can store a second battery. At first I had it behind the driver's seat, but now the space is not so nice because of the swivel console. I would like to attach the battery, or several batteries, to the frame at the bottom of the car. Unfortunately, I don't have a source of suitable frames, I live in Germany. Can anyone give me a source? eBay.com or something elase? I did not found anything where i can be sure to buy the right ones.
Greetings

there is the factory mounting holes

GM part# for factory tray is 20970916

I think you have welding skills right. Might be better to just make your own.

 

Hello,
a Garage near me built a self-welded frame with 2 batteries under the VAN. There are now 2x95Ah installed and I have installed an intelligent battery computer (Votronic S 100) in the B-pillar, which shows me exactly how much capacity is still available, how much charging current is flowing, how much amperes are currently being consumed and how much time is left until the batteries are empty. I set 11.7V as "empty" because they are lead-acid batteries and I don't want to damage them. The computer can also display the starter battery voltage.
Unfortunately I don't have a picture of the frame, which I might add later.

so long...

I would like to see the frame photos please.

That's a nice charge computer, but I wonder what is the burden voltage of the shunt, and if they have a model that uses a hall effect sensor instead.

 

Unfortunately I have no way to lift the VAN in the near future to take beautiful photos of it. Eventually, pictures of it will follow.
The load from the shunt is extremely low, I don't know the exact value right now. But that's exactly why and because of the beautiful display, I decided to buy it.

 

typical burden of the shunts is around 0.1V. So @ 100A, it's burning 10W.

The OEM charging system uses hall effect sensor to measure the current. They have effectively zero resistance.
