stored energy solutions for a demanding world
EosG Series
Model: EosG300
The EosG range of gel technology batteries offers outstanding
performance including a 15+ years design life. The EosG
series batteries is designed based on the Eos series, using
the polymer gel electrolyte. Built to the highest standards and
compliant with the latest IEC60896- 21/ 22 standard. this range
also offers 100% capacity out-of-the- box and is capable of
handling deep discharges for complete peace of mind.
The use of flexible connnectors and the ability to be installed
both horizontally and vertically allows for multiple installation
possibilities.
