All 16 cells found in the same exactly charging level of 3.317 volts.
Thanks for the good quality ,fast delivery and good price of your products.

Good product. Work properly

My HAKADI is working perfectly and with low temperature until now. Thanks HAKADI

It is as it should be, exactly as described, I am very happy, I will definitely buy it again.

The order delayed to dispached, but the battery cells arrived and were as described. All QR codes scanned successfully. My measurements show all cells exactly at the same voltage ( about 70% charged), internal resistant at 20mΩ. I'm not stress the battery yet to see available capacity of 16pcs but discharged till 50% from 80% charged give a value of 6KWh. In conclusion I'm happy and I'll bought again in the future.

Wszystko ok.

AAAAAAAA

It’s been working since purchased (2 months ago) without issues; solid housing, battery compartments precisely sized for 2 rows of LFP105 cells; top quality product. Included BMS specs fit perfectly to dedicated cells configuration. You get complete set of „bolts-and-nuts” (including USB adapter for connecting to BMS) - no need for buying anything else. Once assembled, it starts working straight away. Dimensions of complete box in cm: H 25 x W 35 x D 45 - very compact, fits anywhere. Access to BMS through Bluetooth very handy though signal from inside metal enclosure is weak due to BT module sitting insed metal box - communication works within 1.5-2m radius. It works as part of emergency power supply for my house with 2x2s 500W PV panels, Victron MPPT 150/35 and MultiPlus II 48/3000/35 and it works extremely well. I am very happy with this product. For comprehensive review in Polish, google Marko on YT.

JK BMS V19 with the new screen. Very good price, many easy settings, I recommend it.

Cells arrived in good order , only
one cell had a very slight bulge nothing to fret about.
This particular set of 8 ,could be run without a
BMS; they are well matched -- but i don't recommend that.

8 x 163Ah CALB cells make a powerful 24 battery that can
be still carried short distances.
These cells are quite a bit taller than normal cells , had to make
a cardboard cutout to (8 x cells with .5 mm spacers) to be sure would
fit in battery case with BMS.

Its good that Hakadi deals with the small DIY buyers like me.
They also have a store on AliExpress as well.

Le celle sono di ottima qualità, Assistenza pre è post vendita veramente impeccable, Jacob sì è Reso sempre super disponibile e molto professionale.

16 x LiFePo4 FL105 cells ended in 5kWh (48V) DIY energy store, performing excellent second month already. Capacity exceeds declared 105 Ah when measured between allowed cell voltages therefore 105 is real capacity when battery used in "prolonged service" mode. I am very happy with quality - pristine rectangular shape, full set of isolating spacers, nuts and bus bars of the size adequate to working currents, excellent electrical properties, affordable price. Certainly will return to Hakadi when in need for cells and/or DIY battery box. This one is also well designed, superior quality with more than complete set of guts - you simply buy, assemble in couple hours and it is ready for work. I am very happy with your products. I also appreciate second to none service of your purchasing department. My question (submitted after hours) was addressed in no time yet efficiently. Thank you Hakadi, well done.
