Home > Product & Solutions > SOLAR Series – Hybrid Gel Deep Cycle Battery

By combining the newly developed nano gel electrolyte with high density paste, BSB created the innovative range of Solar batteries. The range offers high recharge efficiency at very low charge current which is very common at renewable energy systems. The acid stratification is highly depressed by adding of gel. This range battery is highly suitable for the energy storage for renewable energy such as PV and wind turbine power systems.
