Y5-BAT | 5040Wh High-Capacity Expansion Battery
5kWh power station expansion battery manufacturer for Y5 and R5 systems
Y5-BAT adds 5040Wh of stored energy to compatible YAZO Y5 and R5 systems. The corrected product baseline allows up to 15 Y5-BAT packs with either host family, while the host power station continues to determine AC output, market voltage and load capability.
Host-First Compatibility
One 5040Wh expansion battery supports two different power-station roles
Y5-BAT provides an additional 5040Wh of energy storage capacity for compatible YAZO Y5 and R5 systems. Both Y5 and R5 systems support up to 15 Y5-BAT expansion battery packs.
| Host Power Station | Verified Y2-BAT Limit | System Role |
|---|---|---|
| Y1 | Up to 15 packs | Adds stored energy to the Y1 2000W inverter platform |
| Y2 | Up to 15 packs | Adds stored energy to the Y2 2500W inverter platform |
| Y3 | Up to 15 packs | Extends runtime on the Y3 3600W platform |
| Y5 | Up to 15 packs | Adds capacity to the Y5 5000W platform |
| R5 | Up to 15 packs | Adds capacity to the R5 IP44 industrial platform |
Expansion Interface
Two covered extra-battery ports support modular system connection
Y5-BAT features two covered EXTRA BATTERY PORTs on the side for connecting expansion batteries. The front display provides battery status information.

Charging Method
Y5-BAT Charging Through Portable Power Stations
Y5-BAT is designed as an expansion battery and requires connection to a compatible portable power station for charging. The battery pack itself does not have independent charging input ports and cannot be charged directly through grid power, solar panels, or vehicle power sources.Y5-BAT receives charging power from a compatible portable power station through the expansion battery connection. Charging performance, including charging power and charging time, depends on the connected host power station model.
For bulk procurement projects, the following information should be confirmed based on the compatible host portable power station before publishing fixed charging parameters or charging time:Compatible expansion battery models,Battery connection interface,Maximum charging power,Charging time specifications.
Energy-Reserve Use Cases
The same battery pack can extend home-backup or industrial runtime when paired with the correct host
Add runtime without redefining host power
The current application image positions the battery around office, home-backup and industrial energy-reserve use. Connected AC power still follows the host Y5 or R5 specification.
Useful when recharge opportunities are farther apart
Additional stored energy is relevant where the application needs longer intervals between charging opportunities. Runtime should still be calculated from the connected host and real load profile.

Updated Pack-Out Evidence
The newest package image now shows one battery expansion cable
Older verification notes correctly treated the cable specification as unavailable. The newer August 26 package material now visibly shows a Battery Expansion Cable ×1, plus the user manual and warranty card.
Battery Expansion Cable ×1
The cable is now visibly included; its detailed voltage/current rating and connector specification are still not published here.
User Manual ×1
Confirm language and private-label document requirements for the destination market.
Warranty Card ×1
Use the approved commercial warranty wording for the final printed pack.
Factory Release Checks
Y5-BAT factory inspection should follow the approved host and pack-count configuration
The current model-specific QC image shows Y5-BAT units at electrical inspection stations. For a bulk expansion-battery order, release controls should be tied to the approved Y5 or R5 system configuration.
- Verify Y5-BAT model identity and 5040Wh capacity marking
- Check status display and both extra-battery connection points
- Verify the applicable charging routes for the commercial version
- Confirm pack quantity does not exceed the verified host-model limit
- Match the expansion cable, manual and warranty card to the order
- Record tested hardware/firmware requirements when supplied for the project
Wholesale 5kWh Expansion Battery Program
Bulk Y5-BAT quotations should start with host type and required energy reserve
We supply Y5-BAT for distributor, project, fleet and private-label expansion programs. The RFQ should identify the host model and required pack quantity before branding or packaging details are finalized.
Y5 or R5
Identify the host because the expansion battery inherits system-output behavior from that power station.
Up to 15 per verified host
State the requested Y5-BAT count; do not substitute a calculated public system-capacity claim.
AC, solar or vehicle route
State which charging routes will be used so the applicable input and cable specifications can be confirmed.
Quantity, label and documents
Provide order volume, branding, packaging, manual language, warranty wording and delivery target.
Frequently Asked Questions
Y5-BAT compatibility, expansion and purchasing questions
Q: Which YAZO power stations are compatible with Y5-BAT?
A: The corrected compatibility matrix lists Y5 and R5 as the verified host models.
Q: How many Y5-BAT packs can be used with Y5 or R5?
A: The verified compatibility limit is up to 15 Y5-BAT packs for Y5 and up to 15 for R5. This page does not convert that count into an unverified maximum-system-capacity claim.
Q: Does Y5-BAT increase the AC output power of Y5 or R5?
A: Y5-BAT adds stored energy. Continuous AC output, voltage, bypass and other inverter behavior remain host-power-station specifications.
Q: Can Y5-BAT be charged from AC, solar and a vehicle?
A: The latest charging image shows AC Input, Solar Input and Car Input. Exact input power, voltage and current values are not stated in that image and should be confirmed for the commercial version.
Q: Is a battery expansion cable included?
A: Yes. The newest package image shows one Battery Expansion Cable, one user manual and one warranty card. Detailed cable electrical specifications still require confirmation.
Q: What are the Y5-BAT dimensions and weight?
A: The current dimensional graphic lists 641.5 × 304.5 × 437.5 mm and 43.85 kg.
Q: Can I buy Y5-BAT expansion batteries wholesale?
A: Yes. Wholesale Y5-BAT requests can be reviewed from host model, pack quantity, charging plan, destination market, branding, packaging and documentation requirements.
Q: What should I provide for a bulk Y5-BAT quotation?
A: Provide the host model, requested Y5-BAT quantity, destination market, planned charging route, branding, packaging, manual language, warranty-document requirements and target delivery date.
