Need more battery capacity for your power needs? Stack a Wattsun Pack on a Wattsun Dock. The intelligent control system takes care of the rest. Stack up to four Packs on a Dock and create a power supply of up to 11 kWh.
 Stackable
 Need more battery capacity? Stack a Pack on a Dock. Each Pack has a battery capacity of 2.3 kWh. Stack up to four Packs high for a total capacity of 11 kWh.
 Hot swapping
 Our battery system automatically discharges the top module first. This allows you to stack a discharged module (even during use) and replace it with a full battery.
 Portable
 Our modules are easy and safe to move thanks to their light weight (less than 19kg!) and ergonomic handles. Lift our battery system with both hands, or use one hand on the carrying strap to keep one hand free.
 Charging with external charger
 When a Pack is stacked on a Dock while charging, the Pack will also be charged automatically. Want a charger to charge your Pack(s) separately? Then order the Wattsun Charger 360 or the Wattsun Charger 600.
 >1000 cycles
 The Pack's lithium-ion battery cells are of the highest quality, guaranteeing a long lifespan of over a thousand cycles.
