Deep Cycle Solar Batteries

Deep cycle solar batteries, gel, agm, lead carbon

The battery powers every off-grid system.

Lead-acid batteries remain the proven choice for commercial installs like telecom sites, remote cabins, industrial backups, and large-scale solar storage. Low upfront cost, predictable scaling via high-capacity 2V cells (up to 4,000Ah), and lead-carbon upgrades combat sulphation for deeper cycling in PV arrays and frequent deep discharges.

Gel and AGM sealed variants add spill-proof reliability, vibration resistance, and zero-maintenance—ideal for marine commercial vessels, remote pumps, mobile generators, and harsh-environment backups.

Fogstar Drift Gen2 LiFePO₄ takes it further for commercial and serious installs. Compact 230–628Ah packs deliver 4,000–8,000 cycles, 10-year warranties, Victron DVCC/Cerbo integration, app monitoring, and cold-weather BMS heating. Replace lead-acid bulk with lighter, faster-charging performance in inverters, telecom, marine, cabins, and enterprise solar—without compromise.
