CALB CA100. LFP4 or Ion ?

[Koontzy]

Hi, just bought a bunch of used CALB CA100. On the sticker it say "Lithium ion battery cell" and everywhere else it say LFP4 battery. Which one it is ? ??
Since the lot came with a bunch of LYP4 Winston WB-LYP100 and WB-LYP300 cells I bought them but I hate dealing with ion battery, especially used

Thanks !

Lithium Iron Phosphate batteries are a subset of all the possible Lithium Ion batteries. There are lots of battery chemistries that are Lithium Ion, and LFP is one of them.

CALB typically makes LFP prismatics. What is the resting voltage?

these are 100% LifePo4 100 AH cells

between 3.29 and 3.38

this lower the cost of the winston cheap cell I've bought so it a nice thing
at the pricepoint I bought them it's basically almost throwaway cell when empty. Now time to find VERY cheap smart BMS (or even non-smart) ?

Thanks !!

Those look like older lfp cells.

Use to see those in posts from old threads in misc forums.

These are WAY bigger and bulkier than my other CATL 271aH prismatic cell. I bought them thinking they would have been easier to move around since it's only 100aH. They are bigger then the 271Ah cell. At least they are lot sturdier and look like I can throw them off a bridge and still be able to use them ?

I personally like the poly outer cell better than the aluminum. They seem more robust and certainly don't bloat with the slightest charge on them.
