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!_*

*_Does he not link them in the description? >:C_*

*_I FOUND THE VIDEO!_* *I will be buying 3 of those batteries real soon!*

Built in jump start thats sick af

Looks so sick!

i would just keep the rear running lights solid... its a bit distracting trying to tell which turn signal is on when they're both goin like that

Race the Hoonicorn RACE THE HOONICORN!!! Someone’s gotta give him a run for his money...

Loose even more weight with the super capacitor batteries.

Hoonigan ken 1000hp mustang vs robs 4 rotor ????? I think so

Still waiting to see this hunk of shit do somethin

I have never seen this guy do anything but fucking talk about his hair promot his money makers and do absolutely nothing .go fucking Duracell the car bro.. wtf its like blue balling us.. flipp off bro

my favorite project man youtube / colleague as i am a Computer Engineer. following rob since day 1. iam glad we found you. Cheers from Rhodes Greece

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 looking for getting your car as light as possible contact philipp keass from germany He has his own youtube channel too and is building everything in carbon and titanium and even started with extra lightweigt glass windows He is famous for his 1300hp audi rs4 m.irpost.info/get/H2qEpwlSWYK7fou3UZ4RjA.html

AWESOME ending!!!

Talks how he got hevy battery got in my a8 100ah battery thats is 2x bigger and ways like 40kg

Weight cuts for wrestling. The best memories

Talking about weight reduction, has 0 track time.

get!

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.

If you ate a 5 pound bag of sugar free gummi bears you could probably lose that weight.

What about High Beams?

That battery for my Impreza is $830.00. it's a great idea but that price is just too much.

honestly rob, stop taking the piss, just produce the car its been years. you can shave 25 pounds with a different seat.

Rob we liek the stock steering wheel! it's cool and original!

Only ten seconds in an i already know you dont own a Beemer !

i see he is back using CAD (cardboard aided design) to build the batery bracket

mbangun montor sitok ae dibsuwebsuweno cak cak

Hey, you're gonna race the hoonicorn?

Will this thing ever see the road/track ? Lol

God damnit!

good kitties 🥰🥰🥰🥰

is he ever going to clearcoat the chassis or get it all powder coated? seems like any amount of weather is going to surface rust the whole thing

This dude doesn’t get enough views, he’s had such bad luck with this car and it’s still gotten this far. That’s persistence😂

i have been with them for along time they do not like heat protect them here is the problem 1500 cca of this lif bat is very voilent if there is a problem do not put it the passenger conpartment if it goes it watch what a 18650 does on a short from impact anything can happen be safe it is a battery and a battery with this kind of power you do not want next to you in a high power vehicle fire is 1 thing a 1500 cca lip battery explosion is another it is like thermite volts on a dead short it is different to put out mount it outside just my opinion anything can happen parts break all the time

Math.... no..... cardboard is universal

I can’t believe how long it hands taken you to build this car, when you first started building it I was a young teenager, now I’m an adult

So like hear me out what if these videos were 5minutes long I would watch every one

It’s looking almost done

Optima batteries suck

lol damn that battery for my car is $829!

German Liteblox Batterys, smaller and lighter

Its not a rob Dahm video if everything goes smoothly.

Lite Blox bulids also very nice and light batteries with awesome features

uh, so, .... *nervous scratching intensifies* uh, y'all got any more of them 4 rotor updates?

Rob, there is an Brand called LiteBlox they do also light batterie out of carbon and there sick AF

so many dummies in here trying to compare to the senna. SENNA IS FOR A CURVY RACE TRACK not a straight line. Senna is slow af for drag strip basically

Wouldnt be pop up headlights without them not popping up

Of COURSE he stops it there LOL

Get rid of the steering wheel

Antigravity batteries. Mind blown

Hurry up and finish it already lol

LiFePO4? Seems like it, looking at the voltages. I've been experimenting with that as well. I just couldn't figure out current limiting for charging while not limiting for starting yet.

5:26😬😬

..... .... . . .. . ..Then shouldn't the video have been 30 seconds long?????

why dont yous use those billet housing made by australian

why'd that pop up made that sound? DID YOU BREAK THE LIGHT?!!?!?

Probably lose 10lb if you ditch the stock steering wheel and airbag

LOL, a $700 battery? Holy crap.

900US Dollars in a Battery? ok..

Its taken me nearly 2 months to lose 25lbs

And I thought you blew your turbo 🤣🤣🤣 this is some awesome tech by the way, true innovation for the sport.

Yo Rob no idea how to get ahold of you man, what's your email or something? Where my dam 1240 shirt i ordered it in fkin September 5th. I got a message about a delivery but nothinggg man how do I sort this out

As a C5 Corvette ex-owner, I appreciate the tribute to the jammed pop-ups.

Will the car ever get the engine bay, and interior covered?

I have a 12 volt 72 Wh Lithium LiFePO4 battery. Weights only 1.30 kg (2.9pounds) Cranking my 1800 cc engine very easy (Nissan ca18det)

You wrestled? I only remember Kev and Matt. lol

What digital power controller are you using, Rob?

That was the longest battery advertisement I've had to skip through

Awesome Project Rob. I use this Battery: liteblox.de/ May you can use this one too? Best regards from Germany :)

Holy smokes.... When are we going to see this car do anything impressive?

*15 pounds lost

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!

Does Rob have a daily driving rotary?

Classic Rob Dahm outro

I swear cyberpunk 2077 is going to come out before I see this car race, not complaining tho, more videos to watch !

So the AntiGravity Batteries is a dry cell lythium battery

Waaaiit, Rob wrestled?? Never would've thought 😂

All that flexin and the headlight lift motor ruined it lol looking good man 👍🏼

You should drill holes on that bracket even more weight lost .....

Bro I love the cat segments

Battery Shutoff ? Hate to get to stage 8 and the charger, and pop! Power manger died. Cant race again bro.

Another place you could shave weight would be to go to a titanium exhaust

BRO HE IS DEFINITELY GONNA BE RACING THE HOONICORN. IT ALL MAKES SENSE NOW!!!!!

Great video battery is awesome those cats are cute.

If the rear running light is like that, that make some people dazed/fixated and likely to rear end you :T

when i see the rx7 i go dahmmm

This channel should be called how to get in over your head but you told the internet you would so you have to continue ....good luck Running autocross in 2035

Rob: [Everyone liked that]

What a great way to end the video! Snagging!!

Rob Dahm; the type of guy to get hyped over a car battery. how humble..

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.

Pop up headlights definitely working like we'd expect them to work on a 90s car in 2020.

You should get the CTEK battery sense instead of the anti gravity monitor

Am I coming here for cats or 4 rotor at this point :)

Great car build, one of my favorites among BOM's project Binky, HBBJ's Alferrari, and GG/CP's King Zero. All such nice people doing these great things.

a whole $800+ battery. NBD

I'm curious what the weight difference between stock and aftermarket column/steering wheel is? That is a really handy battery setup albeit way to expensive for me.

You have Windshield Wipers yet?
