Great product! I use it in my enclosed RC airplane trailer to power a small refrigerator, TV, and battery charger. I followed a YouTube assembly video, and everything works perfectly. I would definitely buy another one from HAKADI.

I bought 16 battery cells and i am very happy with them fast shiping and good quality

Everything it was perfect

The cells were delivered in excellent conditions. All cells of the same production month and all of them with the same voltage. Highly recommendable.

Excellent service and support

Der gesamte Ablauf, von der Bestellung über zügige Lieferung bis zum Nachsenden eines fehlenden Teils lief sehr gut und sehr Entgegenkommend. Gerne wieder.

The batteries were without defect, and they are purple. I like purple.

It is tough to find more to say about them, they are batteries, after all. The box they came in looked cool.

Zakupiłem obudowę do samodzielnego złożenia. Solidna i w przystępnej cenie.

ordered Catl 280Ah battery cells on 20.11.2026 and they were delivered really quickly. On 27.11.2026 I had the cells. I received the tracking IDs for the shipment the next day from the order and it was nice to follow the delivery. Thank you Hakadi.

Great manufacturing quality, I will gladly buy again from the seller.

Une super batterie lifepo pour mon voilier.
Grosse capacité de 660ah avec un bms de 300a.
Pratique à assembler carrément a l'intérieur du coffre dans laquelle je l'ai installée, ce qui évite de porter trop de poids en une seule fois. Fonctionnement parfait pour le moment.

La batterie est simple à monter et à paramétrer.
Avec un convertisseur de 3000 W je peux utiliser tout le matériel électrique dont je dispose.
Je suis très satisfait.
