Excellent value for money Review by Sid

I bought 12 of these for my off grid setup - I have them setup at 24 v and all 7cells are connected in parallel between the 12 packs to control voltage creep and cell mismatch. I charge them to max 27.3 v (3.9v per cell as per saft advice) and my discharge cut-off is 24.5 v - this gives me over 1 KW discharge per pack without any cyclical count. I have discharge tested them from 28v to 24 v and they all discharged around 1.4 KW. Discharge curve of these batteries as per manual shows a steep drop off after 3.2v and so there is little use in discharging them below this voltage. I'm not sure how long will they last but at the moment they are very useable in a low to medium duty cycle use. (Posted on 21-06-24)

I purchased 4pcs for my balcony PV. I connected small 20A BMS in each pack and added some service ports for future external charging and balancing.
All 4 has been tested as following:

Charged voltage: 28,0V
Discharge stop voltage: 21V
Discharge power: 150W

Load: calibrated DL24
Charger: iSDT Air8 with balancing

results of 4 packs:
1. 63,2Ah
2. 63,7Ah
3. 62,9Ah
4. 62,2Ah

I used Fusion360 and my 3D printers to make electronics housings.
