How To: Alternator delete

The first time that I remember changing a car battery, I had my little brother carry it into the store. The employee said "Hey! Watch it! He is going to get battery acid on him!"

I had him set down the battery, took him into the bathroom, and washed him off.

His clothing suddenly had holes.

AGM batteries are dry. No water. Nothing to leak out. They can be used on their side just fine.

Yeah, I think it would probably fit on its side.

Yep, the Prius is mine. My wife drives it typically. The wheels are just the stock wheels on any 2nd gen Prius. They have the trim rings removed because I modded them for pizza pans (which didn't end up working).

What I'm currently thinking is that I have four LiFePo4 A123 amp20 (20Ah) pouch cells. I've always wanted to use them on a car because they are ridiculously light weight. I'm thinking of using those up front and fitting another lead battery somewhere else. I just have no idea where yet. I'll have to come up with some way of monitoring both batteries. Still not set on the idea, but its a possibility.

I just emailed a local guy trying to get rid of some old Thundersky 200Ah cells with ~100 cycles on them. Yeah, they're massive overkill for an alt delete, but if he is willing to let them go cheap, I can make it work.

Still looking into options.

Dropping in a group 24 would still be by far the easiest thing to do and would suit most of my needs.

I'd need lithium cells and a lithium charger at the least, possibly a BMS.

Modify your hood to look like you have a turbo.



Battery chargers are cheap.

Mostly for my own reference, these are the lead acid cells I'm looking into:

group 24, 80Ah, $72
group 27, 105Ah, $75


Ironically, the little 26R OE replacement costs even more than either of the deep cycle batteries above:

26R starting battery, $89


So, its actually cheaper to go with either of the batteries that'll allow me to do an alternator delete... Works for me.

Lol, a Metro with a hood bump... I'd laugh at that.

Actually, I was thinking that you could modify your hood like Aerohead did trying to make the front more aerodynamic. I know that he did not see an improvement, but you could fit all kinds of batteries in there if you raised the roof!

That is a strange love note for your wife!
