- Supports up to 7 packs for 16384Wh total capacity
- LiFePO4 cells rated for 4000+ cycles
- Plug-and-play BMS recognition requires powered-off connection
Who it fits
Good fit for
This expansion battery suits users who already own a BP3000 power station and need more runtime. It is ideal for multi-day home backup, extended RV trips, or off-grid cabins. If you run high-draw appliances like fridges or ACs, doubling your capacity to 4096Wh helps. You can also stack up to seven packs for massive storage. It fits users who want a simple, modular upgrade without buying a new main unit.
Who should skip it
Skip this if you do not own a BP3000 power station. It is an expansion battery only, not a standalone unit. It lacks independent charging ports or a display. You cannot use it to power devices directly. If you need a complete system with multiple output types, look elsewhere. The requirement to power off both units before connecting also limits convenience for quick swaps. It is not for users seeking a primary, self-contained power source.
Verdict: This is a specialized expansion pack for existing BP3000 owners. It adds significant capacity but offers no standalone utility. Buy it only if you need more runtime for your current host system.
ApaxFolleawall B2000L Key Specs Explained
Capacity: 2048Wh
This value indicates the total energy storage in the expansion pack. Adding one pack to your BP3000 doubles your total capacity to 4096Wh. This increase allows for longer runtime when powering essential appliances like refrigerators or medical devices during outages. You can stack up to seven packs for a total of 16384Wh. This high capacity suits users needing extended off-grid power for cabins or RV trips without frequent recharging.
Battery Chemistry: LiFePO4
LiFePO4 stands for Lithium Iron Phosphate. This chemistry is known for safety and stability compared to standard lithium-ion cells. It offers a lifespan of 4000+ cycles, which translates to up to 10 years of regular use. This durability means you do not need to replace the battery as often as with other chemistries. It is ideal for buyers prioritizing long-term reliability and reduced replacement costs over initial weight savings.
Max Expansion: 7 Packs
You can connect up to seven B2000L units to the BP3000 host. This configuration reaches a massive 16384Wh total capacity. This feature supports multi-day home backup or remote work setups. The smart BMS automatically recognizes connected packs, maintaining consistent charging logic and safety. You benefit from scalable power that grows with your needs, avoiding the need to buy a larger, more expensive standalone unit upfront.
Expansion Charging: AC 1800W, Solar 1000W
Even with expanded capacity, you can charge the full system through the host BP3000. AC input supports up to 1800W, while solar input handles up to 1000W via MPPT. This allows you to store daytime solar energy efficiently for nighttime use. The fast charging capability ensures you can replenish the large battery bank quickly. This is crucial for users who rely on solar for off-grid living and need rapid turnaround between cloudy days.
Design and Build Overview
According to the listing, the B2000L expansion battery measures 14.4 inches wide, 11.7 inches long, and 17.5 inches tall. These dimensions define the physical footprint required for your setup. The unit is designed to stack with up to seven packs when connected to the BP3000 host station. This modular approach allows you to scale storage from 2048Wh up to 16384Wh. The physical layout supports this expansion by using a standardized connection interface. You must power off both units before connecting them. If either unit is below 5% charge, you need to connect an input source first to activate the link. This requirement ensures the smart BMS can recognize the new pack correctly.
The listing does not specify the outer shell material or the exact weight of the unit. It focuses on the internal LiFePO4 chemistry, which contributes to a lifespan of 4000+ cycles. The physical design prioritizes compatibility with the BP3000 power station rather than standalone use. You cannot use this battery as a primary power source. It serves strictly as an expansion module. The controls are managed automatically by the host BMS, which handles charging logic and safety protections. This means you do not need to adjust settings on the expansion pack itself. The build is intended for users who need to extend runtime for fridges, ACs, or job site tools without adding a second full-sized power station. The size allows it to fit alongside the host unit in most storage or transport scenarios.
Setup and Everyday Use Guide
Setting up the ApaxFolleawall B2000L expansion battery requires careful attention to power states. You must connect the unit only when both the host BP3000 power station and the expansion pack are powered off. This is a strict requirement for safe integration. If either unit has a charge below 5%, you need to connect an input source first. This step activates the system and allows the connection to proceed. Once powered on, the host Battery Management System automatically recognizes the connected packs. This plug-and-play design means you do not need to configure complex settings or manage charging logic manually. The safety protections remain consistent across the entire system.
In daily use, the B2000L integrates seamlessly with your existing BP3000 setup. Adding one pack doubles your total capacity to 4096Wh. This increase extends runtime for high-draw appliances like refrigerators or air conditioners. You can stack up to seven packs to reach a total of 16384Wh. This configuration supports multi-day home backup or extended off-grid trips. Charging remains efficient after expansion. You can charge through the BP3000 host using up to 1800W via AC or 1000W via solar MPPT. The LiFePO4 chemistry ensures the battery lasts for over 4000 cycles. This longevity translates to up to ten years of service. The smart BMS protects against overcharge, over-discharge, and temperature issues during everyday operation.
Before You Buy This Expansion Pack
You need the BP3000 host unit to use this pack. It does not work alone. Check that your main station supports up to seven expansion modules. This stack reaches 16384Wh for long off-grid stays. You should also verify solar input limits. The BP3000 handles 1000W MPPT input. This pairing stores daytime energy for night use. LiFePO4 cells offer 4000+ cycles and a ten-year lifespan. This chemistry is safer and longer-lasting than older types. Keep both units powered off before connecting. If battery levels drop below 5%, plug in an input source first. This expansion fits well if you already own the BP3000. It adds significant capacity without buying a new system. Other portable power stations may not accept these packs. Confirm compatibility before adding this to your cart. It is a specialized add-on, not a general replacement.
Check before you buy
- Confirm you own a compatible BP3000 power station host.
- Verify the host supports stacking up to seven expansion packs.
- Ensure both units are powered off before connecting modules.
- Check if input sources are needed if levels drop below 5%.
