What are the main advantages of LiFePO4 batteries?
Service life of 4000+ cycles at 80% depth of discharge (over 10 years of daily use), up to 98% energy conversion efficiency, 100% usable capacity, discharge from −20 °C to +60 °C, thermal stability and no lead or cobalt.
How long do the batteries last and what warranty is offered?
Cycle life is 4000+ cycles at 80% DoD for the 12.8 V batteries. We offer up to a 10-year warranty on stationary systems; the exact term depends on the product.
What does the built-in BMS do?
The smart BMS (up to 200 A) monitors every cell voltage in real time, balances cells actively, protects against overcharge, deep discharge, short circuits and overheating, and tracks State of Health (SOH) and State of Charge (SOC).
What is the difference between the 12.8 V 12 Ah and 20 Ah models?
The 12 Ah (153.6 Wh, about 1.5 kg, 151 × 99 × 99 mm) is a compact option for portable electronics, fishfinders, alarms and routers. The 20 Ah (256 Wh, about 2.2–2.3 kg, 181 × 77 × 167 mm) gives higher power and longer runtime for e-transport, marine, camping, solar, medical and industrial equipment. See full specifications.
Can I connect several batteries together?
12.8 V 20 Ah batteries can be connected in series — up to four units — to build 24 V, 36 V or 48 V systems. Parallel connection depends on the BMS and is not recommended without consultation.
Which solar inverter brands do you supply?
We are an official dealer of Solis, Deye, Growatt and GoodWe. See examples from their catalogs on our Solar Inverters & Storage page.
What types of inverters are available?
