Car Battery Alternative

lifepo4 is a type of li-ion. so yeah lifepo4 is a li-ion battery. there are other li-ion chemistry out there like NCA, NMC, etc.

i've seen ads by readygo. i wonder how long they actually last inside a hot engine bay.

Agree on the two batteries' relationship. I would call them Lithium-based rechargeable batteries in general. I just felt the need to refer to them in exact terms, IMO... LFP vs Li-Ion. There are "Li-Ion" cells and there are "LiFePO4" cells. They have vastly different characteristics, not the least of which is nominal voltage, energy density, cycle life, etc. Having that distinction removes any confusion on what specific battery chemistry is being discussed. That's why I meant by splitting hairs. ;)

For the same reason, I wouldn't use Li-Ion cells inside a hot engine bay due to their explosive nature. LFP cells on the other hand, should fare significantly better under the same conditions.

Curious also how those ReadyGo LFP packs are doing.

i like kfc and mr donut.
why are there no kfc or mr donut beside motolite store?
heh heh.

In my neckodawoods, there's 1 outside their regional HQ....serving the neighborhood their fingalickin' good original & upset-stomach-inducing spicy fried birds 24/7.[emoji4]

but that's not accurate and that nomenclature isn't adopted by the industry.

in front of me right now are a bunch of A123 ANR26650M1B cells. they're lifepo4 in metal can format 26650. they're lithium ion cells, it says so right there on the title

also got a bunch of panasonic NCR18650. "ncr" is panasonic's name for "NCA" chemistry used in tesla model S. can be discharged down to 2.5v. also a lithium ion

got 102 cells in 17s6p pack made from samsung 26F cells. "NMC" chemistry. cutoff is 2.75v instead of 2.5v on the NCA. again, lithium ion

3 different chemistries, 3 different characteristics and voltages. all are lithium ion. the industry refers to them as lifepo4, nca, and nmc. btw there are other chemistries out there outside of these 3 common ones. then there's sodium, etc

btw i graph battery discharge curves for fun

The excerpt you put up clearly states it's an LFP. Anyway, you are correct naman and you made your point. But say, if I search for "Li-Ion", I'm shown cells with a nominal voltage of 3.7V. If I look for "LiFePO4" instead, I end up getting results for 3.2V cells. So again, to me at least, it's not helpful to refer to LFP cells (and other lithium variants for that matter) by their generic "Li-Ion" catchphrase because they all have very different characteristics.

FWIW:
Would I leave a "Li-Ion" battery inside my car, engine bay, or trunk? I most certainly will NOT.
Would I leave a "LiFePO4" battery inside my car, engine bay, or trunk? Sure!

That's the kind of distinction I was trying to convey.

5yo din44 stock battery on the ecosport. 220cca nalang but still started w/o hesitation. at that point pinalitan ko na.

your 356cca probably has some life left in it

btw i wasn't afraid to drive around w/ such a weak ageing batt coz it's an m/t and i have a jump-start powerbank

ayun na nga bro, AT kasi kaya medyo alangan ako.
kaso madami pa nasa lazada cart ko [emoji1787][emoji1787]

Same tayo. 356cca na lang din yung 3SM battery na nakalagay sa vios gen1 ko. Hehehe.

Sa innova yun talaga..mahina na cranking for diesel pero mukhang malakas naman for gas kaya pinapalit ko muna. Once a week lang naman ginagamit yung kotse eh. Hehe

oo nga, buti kumasya at hindi tumama sa hood.. laki nun 3sm.. for gas engine, malakas pa yan 300cca.. hehe

sa diesel medyo delikado na yan..
