Each Dyness battery undergoes 1-2 cycle tests before shipping and has CE/FCC/UN38.3 certification to ensure maximum safety for our customers. Dyness maintains a local warehouse in Germany to ensure efficient shipping. In addition, we offer a 5-year warranty. If you have any questions about our products, we will reply to you within 24 hours!
Class A+ battery cell, 4,000 deep discharges: The Dyness 100Ah LiFePO4 battery uses four high-quality lithium iron phosphate cells of class A+ (3.2 V, 100 Ah), which are arranged in a safe 4S1P configuration (4 in series, 1 parallel). This ensures a stable output voltage of 12.8 V and a capacity of 100 Ah. Each battery allows up to 4,000 deep discharge and full charge cycles at 100% capacity retention (max. 15,000, 50% capacity retention). Dyness lithium batteries are far superior to lead acid batteries in terms of cycle count and battery life. This saves you time as you do not have to replace the batteries frequently.
An ideal replacement for lead-acid batteries: the Dyness LiFePO4 100Ah battery weighs 9.9 kg and measures 33 x 17.2 x 21.4 cm. This makes it lighter than lead-acid batteries (over 65% weight reduction). It can replace lead-acid batteries in most applications, including RVs and camping, solar systems and off-grid living, household energy storage and marine applications. Lead-acid batteries tend to cause significant loss of capacity and data distortion with increasing service life. The choice of a lithium battery 12 V 100 Ah ensures the stable operation of your application.
100 A BMS and low temperature shutdown: the battery management system (BMS) of the Dyness lithium battery (12.8 V, 100 Ah, with 100 A BMS) has extensive protection functions, including overcharge, over-discharge, overvoltage, short circuit and deep discharge protection as well as a low temperature shutdown. If the temperature drops below 0°C, the lithium battery interrupts charging. If the temperature drops below -20°C, the lithium battery interrupts the discharge process to avoid damage.
