My work truck has 2 batteries, it was a bit over $450 total 2 months ago
Im building a race car, for an extra $350 I can get a battery that weighs 2kg instead of 14kg.
Like... It does nothing else special other than weigh a shitload less.
That is a shitload , though hopefully not literally.
Seems worthwhile in this context, though.
Yeah, Im building a barely street legal "smiles per gallon" toy... in a 1025kg car I can save around 12kg each on the battery, spare wheel, aircond, back seat and wheels, few more on the carpet and sound deadening... few more on the flywheel. doesnt sound like much but the car will be about 6% lighter overall. Thats the low hanging fruit and the expense of losing more will be where it costs big cash or the car becomes illegal.
When you really get into the nitty gritty with weight savings, 350 bucks for 12 kg of weight reduction seems like a total bargain.
You should post your project on !cars@lemmy.world :D
Yeah its pretty much a bargain in terms of weight reduction, but I'm also not tearing out a perfectly good $200 lead acid and then spending $550 just to save some weight while I still have repairs to do just to make the car "good" and "safe" LOL.
We are early in the project but I will take the time to post it up on here too.
Same capacity and CCA or do you have to make sacrifices?
Less AH but thats a minimal concern.
Well for a race car yeah, I was just wondering if the technology existed to make regular car batteries lighter without any sacrifices besides cost. I guess Lifepo4 is an option, but not in the cold.
Honestly I'm not really sure about the long term drawbacks of running one in a street car.
Ah I run aged luxury cars in a cold climate so personally I'm not a fan of "less Ah" but for most people it should be fine.
