That battery that makes you car and wallet a lot lighter.

You're probably right about the emergency start mode Lithium chemistry batteries require a minimal charge to function. Full drain destroys them, so all well designed Li batteries include a small battery management circuit board for min drain, max charge, charge balancing the individual cells, etc. aside from other features, great for making sure they don't explode.

*_I'm trying to find that battery. Dahm said it is the biggest one but I can't even find it online. I found the Ctech charger tho. If anyone knows the website let me know ASAP!_*

www.mazdaforum.com/forum/mazda-rx-7-33/joe-maddox-super-rare-1-100-1989-fc3s-gtus-rx7-2jz-gte-vvti-build-43602/ I have found and saved the rarest Mazda FC RX7 ever made! Now this car is rare. Really rare! Let me break this down really quick... Ever heard of the rare 100 GTUs rx7s? Only 40 have ever been claimed and only 11 are confirmed at the time of this posting! Here are the rarest rx7 FC3S models: 1500 10AE Turbo models 1400 infini 1000 winning limited 150 final edition convertible 100 GTUs... out of that 100: 83 red on black 10 black on black 7 white on blue There was only 100 GTUs models created between 1989 and 1991. If you own one of these rare models sign your car up to the registry list here on any of the rotary forums! There are rumors about a restamped GTUs model... The entire origins GTUs owners thread on the rx7club was modified, icemarks claims deleted, registry list changed to have a confirmed section and the mods agree there are not enough GTUs models to have the restamped. If you want the full story behind the restamped models: www.mazdaforum.com/forum/mazda-rx-7-33/restamped-mazda-rx7-45926/ www.rx7club.com/2nd-generation-non-technical-pictures-198/restamped-mazda-rx7-1148475/ If you have a real GTUs you can register it here: www.mazdaforum.com/forum/mazda-rx-7-33/official-mazda-rx7-gtus-owners-club-thread-44477/ www.rx7club.com/2nd-generation-specific-1986-1992-17/mazda-rx7-gtus-1148362/

Hey them kitties are awesome. Check if they're spayed or neutered. It helps if you get them neutered because then that's less kitties suffering. I have random Kitties that I'm taking care of and this is something I'm doing to help quell the population of them.

I can’t wait till you get the 4 rotor finished enough to race! I saw hoonigans “this vs that” special featuring the hoonicorn and I can only imagine that’s race you missed. If it’s not then you should hit up your friends at hoonigan and see if you can make that happen. I honestly can’t imagine very much beating the hoonicorn.. but I think the 4 rotor has a real shot at it. Even if you lost it’d be great to see you come close considering you’ve built this car yourself and how far you’ve come doing all the work by yourself and a few friends!

There is an automotive spec for certain automotive systems (like fuel pump or control modules) where the component has to turn on at 6v. Some window switches/motors get tested at 6v (especially at -40C). Goes really slow.
