Features
BERSH Series, with its proprietary grid alloy and paste formulation, provides superior performance in both high cycling and floating applications.
By combining the newly developed Nano Gel electrolyte with high density paste, it offers high recharge efficiency at very low charge current.
The acid stratification is highly reduced by adding Nano Gel.
It is suitable for off-grid photovoltaic, wind or hydro power application.
