BYD BYD Battery-Box Premium HVS 10.2
JouleSpecs does not sell and does not show shop prices: check the price where you buy.
Lithium iron phosphate (LiFePO4) modules, in a tower paired with a compatible inverter chosen separately.
The round-trip efficiency is at least 96%. The battery keeps working even without internet: the connection is for remote diagnostics, not for operation.
Commissioning, on the other hand, does require the app, done by connecting to the battery's own Wi-Fi access point.

A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.
What it really costs
How we worked it out
- stated cycles
- 3650
- warranty years
- 3650
- guaranteed energy throughput
- 3010
How we worked it out
- usable capacity
- 10.240
- weight
- 167
These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.
Pros and cons
In favour
- The round-trip efficiency is high: what goes into the battery comes back almost entirely available when needed.
- The design is modular and can be expanded at any time.
- It works even without a stable internet connection: the network is for remote diagnostics and updates.
- The official list of compatible inverters is extensive and covers different brands, including GoodWe and KACO.
Worth knowing
- The warranty expires at 30.82 MWh of minimum throughput energy or after ten years, whichever comes first: anyone cycling every day can reach the threshold before ten years.
- Commissioning requires the Be Connect app on a smartphone: without it the system cannot be configured.
- The system's usable capacity can vary depending on the brand of inverter it is paired with.
