The expansion battery for the BLUETTI Apex 300. 5,120Wh that nearly triples the Apex tank without changing anything else about how the system runs. Delivered anywhere on Hawaii Island.
READ THIS FIRST
The B500K has no solar input and no outlets of its own. It is a tank, not a power station, and it only works plugged into an Apex 300. If you do not already have an Apex, buy the Apex and add this to the order.
WHAT IT CHANGES
An Apex 300 on its own runs a fridge, a freezer, a catchment pump, a UV sterilizer, lights and Starlink through a full day with zero sun. With this battery behind it, trim to essentials and it stretches to about three days. You keep the 7,680W surge that starts a pump motor and simply gain endurance.
SPECS
5,120Wh LiFePO4, 4,000+ charge cycles
Connects to the Apex 300 with the supplied cable
Up to six batteries per Apex, for just under 20kWh
Only five of these exist. When they are gone they are gone.
Extra wiring runs are $1 per foot, quoted on site. Questions? Call or text 808-319-6399.
