The SMD / SMT battery holders are your friend. Used in vaping. Contacts are leaf springs made of bronze. I'll be using them for the alternator delete build.

An interesting new product at battery hookup:

LithiumPower 12.8v 32ah 410wh LifePo4 Module w/ BMS

Drop in replacement small battery for a car? Perhaps. I'm a bit leary of the 32A max charge and discharger, but I assume that is probably continuous because that is 1C. For starting I think it would be fine. Two in parallel would be more ideal though.

I use a 20ah LiFePO4 to start my car. In the transitional seasons it starts just a hair slow, so I have a small cap pack (6x 400F) aiding it. My bet is that battery would do fine in my car without the caps.

I don't use lithium in winter, however.

A small LFP battery can still work fine in the winter, the problem is you need to have a method of warming the battery so it can accept a charge. LFP is still more economical if you're willing to deal with a heater (a quick and dirty way to get it done is to have a heater pad that consumes enough power that an idle engine doesn't produce enough extra amps to charge the battery, and switch it on immediately after cranking).

I was talking to a manufacturer who can provide 40Ah LTO batteries (which can charge in the cold) in a plastic case with SAE terminals, but the cost is fairly high; The final cost if I were to resell them would be around $500. This would be a true no-compromise lead acid replacement that lasts forever, has ample reserve capacity, and has great cranking capacity. I've been thinking about starting a business selling these to luxury sports car owners, since they pay well over that amount for LFP batteries.

You can get a smaller LTO battery with no BMS for less money, and just run it with a balancing circuit. Used cells (which retain most of their performance since the LTO chemistry is more durable) should be able to get you around 20Ah for under 100 bucks total.

Another update guys. Battery Hookup currently has brand new Honda Insight batteries available.

They have a lot of cool stuff right now. Worth looking into if you're in the market for any batteries.

Was just looking at that site the other day, really impressed with the battery selection they keep bringing in.

Man, this package right here:

Would make a nice drop in for us first gen owners... 176.4v high, 117.2v low. Looks to be already wired for a BMS and everything.

Right now these guys got a hold of a bunch of Renology solar panels and 12V lithium batteries in 100Ah and 170Ah flavors (as well as some AGMs). Worth a look if you have any interest in solar or batteries.
