The Aferiy P310-B adds 3840Wh of LiFePO4 storage to an existing P310 power station. Connect one unit and you're at 7,680Wh total. Add a second and you're at 11,520Wh -- enough to run a full homestead through a multi-day outage. This is a slave unit. It requires a P310 to operate. If you don't own a P310 yet, start there.
Aferiy P310-B Expansion Battery Key Features
- 3840Wh LiFePO4 capacity per unit -- adds 3840Wh to your P310 system per battery connected
- Scales to 11,520Wh total -- pair two P310-B units with the P310 for maximum capacity
- 4000+ cycle life -- same LiFePO4 durability as the P310 base unit
- Plug-and-play parallel connection -- parallel cable included, no configuration required
- USB-A QC 3.0 (18W) and USB-C PD 3.0 (100W) ports -- the battery itself has pass-through output ports
- MPPT input (11.5-50V, 200W max) -- can accept direct solar input independently
- Compatible with Aferiy P310 only -- not compatible with P210, P280, or other brands
- 36.5 kg, compact form factor -- same footprint as the P310 for clean side-by-side stacking
