DETAILS
BLUETTI P090A Battery Cable
The long link for your expansion battery
The P090A is BLUETTI’s long (800 mm) external battery connection cable. It connects a B300K expansion battery to an AC300, AC200MAX, AC200L or Apex 300.
Use it when the battery sits beside the power station instead of underneath, or to start a second stack once you pass three batteries on an Apex 300. It’s also the cable BLUETTI specifies for B500K batteries on the AC300, AC200L and AC200MAX.

Flexible layout
Put the battery where it fits
A short cable means stacking. The P090A gives you 800 mm to place the battery beside the power station instead.
- ✓B300K to AC300, AC200MAX, AC200L or Apex 300
- ✓B500K on AC300 (up to 4), AC200L and AC200MAX (up to 2)
- ✓Battery 3 to battery 4 when starting a second Apex 300 stack


Up to six batteries
Two stacks, one system
An Apex 300 takes up to six batteries. BLUETTI suggests a second stack after three, with the long P090A between battery 3 and battery 4 and short CA90 cables within each stack.
Short cables are more efficient; long cables give you layout freedom. Not sure which you need? contact our team.
Frequently asked questions
Which power stations is it for?
BLUETTI lists the AC300, AC200MAX, AC200L and Apex 300. It connects a B300K to any of them, and BLUETTI also uses the P090A to add B500K batteries to the AC300, AC200L and AC200MAX.
How long is it?
800 mm. BLUETTI’s short cable (CA90) is 270 mm.
When should I use the long cable?
When the battery sits separately from the power station, or when you go past three batteries on an Apex 300 and start a second stack. Short cables are more efficient, so use them inside a stack.
Does it work with the AC500?
BLUETTI’s AC500 uses a P150D to P090A cable instead, so this is not the cable for it.
