I bought the Humsienk 12V 100Ah (1280Wh) LiFePO4 battery to build a DIY home backup power station, and I am extremely satisfied. The real capacity perfectly matches the declared specs (I verified this myself using a high-precision coulomb meter). It handles heavy loads easily through my inverter without any significant voltage drops, and the terminal build quality is solid and reliable. I use it to run my household electronics, TV/console setup, and even to charge another portable power station via DC during blackouts. Excellent value for money and a very stable power source. Highly recommend!
