very good battery. It's the second time I buy such batteries

Thank you very much for your fast response and shipment. The product arrived in excellent condition and packaging. I put the battery in my boat works perfect. Also I like Bluetooth and the app . You can see everything about battery in the app very useful. Sure I will buy again. Thank you

the products are in very good condition and the service is very fast

Very strange, why 12pcs was sent separate, so I received 6pcs one day, ant another 6pcs next day or day after can't remember. Anyway, very fast delivery (I think 3 days for first pack, 5 for second). After a month of usage bought YR1035+ lithium resistance tester, tested few cells, resistance better than expected (0.22 mΩ). Can't test capacity.
Anyway, very happy, using in Car Audio, much better than AGM battery I have used before.

Sehr geehrte Damen und Herren, ich habe das BMS dankend erhalten. Der Test mit einem kleinen Battery Pack (10Ah) war zufriedenstellend. Der Test mit dem großen Battery Pack (210 Ah) kann erst erfolgen, wenn die Lieferung erfolgt. Leider gehören eine Anleitung und Anschlussleitungen nicht zum Angebot.
Mit freundlichem Gruß

5-2-2024 Weather station needed replacement rechargeable that had very specific capacity AND size. This is done as to not have rattling around to where the sensors give off false readings, So far, the battery are maintaining a 2.8-2.83 battery capacity and the weather station has been reporting accurate measurements which leads me to believe that we have a clear winner in this battery. Now, you will need to make modifications (ie soldering leads) to the battery but nothing too terribly difficult if you know what you are doing. And finally, do NOT forget to apply dielectric grease to the finished install as was done on the original board. This battery is a clear choice thus far. Thank you, Hakadi for your product!!

I purchased 4 x 18650 Sodium Ion batteries simply out of curiosity, on test they lived up to their specifications.
I will try some of their 10ah Sodium Ion batteries next time.

Excellent
