Take your mobile power setup to the next level with the BigBattery 12V 2X HUSKY 2 Lithium Battery Kit – Victron Edition, delivering an impressive 10.24kWh of ultra-reliable LiFePO₄ power. Whether you're hitting the open road, setting sail, or going fully off-grid, this high-ampacity kit offers unmatched safety, efficiency, and seamless integration with your Victron system.
At the heart of the system are two of BigBattery’s HUSKY 2 lithium batteries, our most energy-dense 12V solution to date. Each battery features Tier 1 LFP cells, a rugged IP65-rated enclosure, and advanced BMS protections, including over/under-voltage, over-current, thermal monitoring, and self-heating technology for winter-readiness. Full CANBus and RS485 protocols provide total system transparency.
We’ve paired these batteries with Victron’s latest MultiPlus-II 12V inverter/charger, a feature-rich solution offering PowerControl, PowerAssist (up to 100A), built-in copper transformer, and remote monitoring via WiFi. This Victron Edition kit ensures your entire setup runs smarter and more reliably—whether on land or water.
