See last post, couldn’t figure out how to delete.

Got 2 other questions. Anyone know what size the battery tray bolts are? It appeared to be 1/4” but it’s not 20 or 28 threaded. Of course my bolts from my 97 are missing and it looks like they just pass through the threaded fiberglass of the body into the round metal tabs glasses into the battery tray. Am I missing other parts? That seems like a very strange way to do it. It’s weird it’s not bolted in as that’s a lot of weight being supported. So the battery tray is being supported by the threads of the blots?

Also an update I got my battery pack together and I’m individual pre charging the battery’s before adding them in the chain. I’m also adding a remote disconnect (to reduce battery draw when parked) to the 12v accessory battery and remote charging terminals as well. I’m thinking of adding remote terminals for the 72v side as that way the system can be externally charged even if the onboard charger goes bad. Would the 72v pack need a disconnect as well? Or would that little amperage on the battery side not affect the charger if it’s not in use?

I think the tray bolts are metric. And it is a lot of weight but it is a sheer load you are looking at.

A disconnect on the bank of batteries is not a bad idea as long as you have access to everything now.

The ambient temp would prob have more effect on the bank of batteries than non-use drain. at least in hot weather

If you run right after individual charging of the batteries you may notice incorrect readings on the
“gas gage” until the batteries are level charged which is the 2nd stage of charging of the on board charger.

Being a pilot, by any chance do you do any drone flying?? just asking....

Ok thanks I figured it might be metric. To keep everything simple I’m going to do a disconnect on the 12v and remote terminals for the 12v and 72v systems. Hopefully my onboard charger and controller are good, I’ll find out this week 🤞

Haven’t messed with drones much I’ve almost hit 2 over the years.

one additional thing, you might like to install two volt meters, they give you a better idea on battery usage/reserve during quick starts. you can just run wiring while all is apart then add them in the future. you can get digital meters for about a buck and a half, on ebay. there is a earlier post of my 2nd installation, I think its somewhere around post 200-300. for first meter installation :

Was wondering what engine people are using for conversions to gas?

[ewpwbwi]

I think they keep a small can of gas in the trunk...lol

Well I finally got the new batteries hooked up (charged 2 weeks ago) and seem to have run into an issue or two. the charger kicks on and sounds like it’s doing something, the fan is running for sure but the main battery pack is drawing down slowly from the 77v it was at, not charging. I am sure the battery discount switch in the back is on. I also tried a function test of the motor to make sure it would work and all I got was beeping and a low battery level indication. No movement of the wheels forward or reverse. I’m going to disconnect the batteries and top each off then immediately try again. am I missing something? I wouldn’t mind buying a new charger if I know it works just starting to worry something else is wrong. Oh by the way it has 23 miles on it 🤣

This is what battery light was flashing realized the picture was mid flash the battery indicator bar by full is also flashing.

Ok the 40amp fuse before the auxiliary battery was bad now the aux battery is charging but the main battery pack is charging really really slow. I think I saw an in-line fuse connecting to the smaller positive wire of the main battery pack I’ll try replacing that. Also do I need the controller to tell the car there’s new batteries? Just because I’m still not getting wheel movement. Thanks


Any thoughts on why the main batteries don’t seem to be charging or why the car won’t drive. I did check the accelerator petal does make an electric click when pushed. Thanks in advance.
