Do you recognize this BMS?

[0ke#]

Hi,

I bought this Aliexpress battery pack (PAPOOL LiFePO4 Official Store). My question is which BMS is it actually using? Within another thread I found a reference to the BMS manufacturer but this manufacturer seems to be very unknown (DAREN http://www.szdrgk.com). But maybe I have some luck and this is just some OEM of a well known brand.

This is the thread where I found the reference (https://diysolarforum.com/threads/red-diode-on-aku.52451/): The translated data sheet from the BMS is attached.

These are photos of the system and some PCB identifiers (I had to open the box):








Main PCB: DR48200JC-02-V1



LCD panel: DR48100LCD-01-V0



I guess the current PWM controller: DR4820LT-01-V1

From the data sheet:



Hope you can help.

Best regards,

Bump! I have 8 of these packs from another supplier but same BMS... Also wondering what this mystery BMS is and if it could be JBD compatible? Anyone know? I think the CEERRNS Batteries use the same BMS and in fact it looks like almost all the legit battery sellers on Aliexpress are using the same BMS according to the LCD, port layout, and interface button layout and welcome screen message. @Steve_S Would you happen to know or recognize these boards?

old tread, but I just add info that Aliexpress seller JOSMA use same BMS as well.
Com protocol is quite similar to Seplos BMS.

I have the same brand (DAREN BMS) on my first 100A Odipie Battery pack and it is a nightmare to make it communicate to Victron GX.
I have given up and built my 304A pack based on Seplos which works seamlessly with the Victron System

by com port do you mean RS485 or Can Bus Please?

By Com protocol I mean communication protocol. It has only RS485.
