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.

JK Balancer 4S 8S 12S 16S 24S 1A 2A Smart Active Equalizer Balancer Bluetooth APP Li-ion Lifepo4 LTO Battery

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.

HAKADI 48V LiFePO4 Battery BOX With JK BMS For 16S 280Ah-314Ah, Solar System

Super i will buy again

Being new to shipping by sea, Hakadi contacted me by Whatsapp and kept in touch with tracking information untill final destination.
My cells were ordered in late May 2025, arrived safely and securely packaged and undamaged, when checking the Genuine and original code identifier i was pleasantly suprised to find all of my cells were manufactured by EVE in late December 2024, they are genuine fresh cells. Will not hesitate to order from Hakadi in the future, if you are concerned with purchasing due to unscrupulous sellers on the internet, Hakadi is safe with genuine A cells from EVE as per sales description. Regards from Australia.

I had 6 pannels 48V 550W and the system not working properly. Today I connect
6 more and then reconnect the outside power and the house working properly.
Thank you.

These came in really good quality

Bought 4 3.7v 314AH cells CATL brand and am very pleased, cycle tested I get 345AH and that wasn't to 10v as I stop at 11.2v so yea they are great.

Battery works good. Cooperative with jk BMS well. I like especially flexible bus bar.

Perfect
