Lithium iron phosphate bms, will it work with li-ion?

[silviasol]

Is the description/title of this bms correct? The specs in the description looks like li-ion but it says it is for lithium iron phosphate. This one has 4 fet and handles 40amp instead of the 3 fet 15amp li-ion one I was looking at. I would ask the seller but I assume this english is terrible as phosphate isn't even spelled correctly. Unbelievably cheap

edit in the title it says "Type of batteries : lithium cobalt / manganese lithium / ternary materials", these are all 4.2v chemistry right?

It's for li-ion, you can se by voltages. It's not for lifepo4.

Also, i see 10 wires on the balance plug, ie : NOT Lifepo4

36v lifepo4 requires 12

I just bought three. I only see good feedback for them so I am guessing it is li-ion but I guess no one bothered to comment to the seller that it is not for lifepo4? Can you confirm by the components on the board that it is li-ion?

edit: ok I see on the actual board it says 36v so I guess good to go then!

use this data to match up with cell chemistry

hopefully you can adjust the min and max voltage for the type of batteries you're going to use.

 

[riba2233]

You can't, these simple bms's use fixed values.

i don't like this design with the opto transistor circuit either. this is just a copy of ping's original v1 except this one has less than half the balancing current of the ping. and fewer mosfets on the discharge too.

How much is ping's? I will be using two, one with each 10s 10ah pack so the discharge amps will basically be doubled.
