What is
IP65 protection?
IP65 protection?
With IP65 certification, Star batteries are fully protected from dust and resistant to water jets from any direction. That means you can safely install them in a garage, basement, utility room, or even in a covered outdoor area — without worrying about weather or dirt.
Recommendation for outdoor installation:
Install in a protected outdoor cabinet, ventilated technical room, or under a roofed structure. Avoid direct weather exposure to ensure battery safety and long-term performance.

What means 90%
depth of discharge?
depth of discharge?
Most battery systems only let you use 50-80% of their total capacity. Star batteries give you up to 90% usable energy, without sacrificing lifespan — so you get more value, more self-sufficiency, and fewer charging cycles.
Standard batteries (e.g. lead-acid)
Typically only 50-60% depth of discharge to preserve lifespan.
Lower-cost lithium-ion batteries
Often around 80-85% depth of discharge.
Ngen Star EP
Offers up to 90% usable energy per cycle — without compromising battery life.
Ngen Star EP 5
