Product Description

  • INCREASE CAPACITY – With an additional 2562Wh; this expansion battery will keep your B4000 SST running for even longer. With a full ETL certification, safety features include over voltage, over current, overcharging, over-discharging, thermal, and short circuit protection. The SST battery is rated for 4,000 cycles to 80% (11 years of everyday use).
  • ADVANCED SOLID-STATE TECHNOLOGY—Solid-state technology (SST) is the evolution of lithium batteries, which provide safer, more compact, and lighter power output than their conventional lithium-ion or LiFePO4 counterparts. The new solid-state battery provides safer and more compact power for off-grid and recreation use.
  • FLEXIBLE POWER STORAGE – 48V DC output is available for use when running the
    expansion battery independently, an adapter is included.
  • AWARD-WINNING COMPACT DESIGN – A single solid-state cell holds up to double the capacity of a LiFePO4 battery cell. This maximizes power efficiency in a smaller, lighter, compact unit. Why lug heavy equipment, with Yoshino you don’t have to.
  • MORE POWER WITH INFINITY LINK- Infinity Link allows the ability to connect additional 2,562Wh batteries together to increase capacity. With integrated Infinity Link technology, you can link up to 15 expansion batteries, allowing the ability to match just about any capacity needs of up to 38kWh.
  • HIGHER SOLAR INPUT – This battery is great for increasing the watt-hour capacity. It will also add an additional solar input of 1200W to the Yoshino B4000 SST when off-grid, camping, or in emergencies. Quiet, emission-free, and reliable.
  • FAST RECHARGING – The EXB1 can be recharged using AC fast charging (0-100% within 90 minutes) and optional solar charging (1200W, 3 hours).
  • WHAT’S INCLUDED - (1) EXB1 Expansion Battery, (1) Expansion Cable, (1) Solar Charging Cable MC4 to XT60, (1) Cigarette Car Charging Cable, (1) 48V DC Out Adaptor, (1) User Manual.
