2021 Update: We’ve also written about the BYD Battery-Box HV – click to learn more!

BYD B-Box Australia – we wrote about the B-Box from Chinese manufacturer Build Your Dreams a few years ago and how the BYD B-Box compares to the Tesla Powerwall 2 – it has continued to see a lot of interest over the past three years so we have an article today with some more detailed information about the BYD’s product range, pricing, and some live data from the field to see how the B-Box performs in real-world settings.

BYD B-Box Australia – Price

The B-Box comes in high voltage (HV) and low voltage (LV) – with the B-Box LV Residential the most popular energy storage device BYD sell. It has a higher IP rating than the Pro variant, and separate circuit breakers for each battery module. 

It comes in four different sizes – 2.56kWh (2.45kWh usable), 5.12kWh (4.9kWh usable), 7.68kWh (7.35kWh usable), and 10.24kWh (9.8kWh usable). All four variants are IP55 rated and modular – meaning depending on the case you purchase you will be able to start small and upgrade if need be. You can get a total capacity of 57.5kWh which would work for light commercial usage. 

We’ve got some pricing available from some sites below, but please feel free to contact us if you’d like a hand with quoting of getting access to a specific B-Box:

BYD B-Box Pro 5.0 – 5.12kWh – $5315.00 ex GST

BYD B-Box Australia – Review

Things we like about this battery – it has blackout protection, is suitable for single phase and three phase power. They have local Australian support and offer a 10 year manufacturer’s warranty. The batteries are modular and can be partnered with inverters such as GoodWe and SMA Sunny Island for on-the-go monitoring. You can use them on or off-grid. 

The B-Box HV received the “PV Magazine Top Innovation Award” in 2017 and BYD’s factory is currently producing a massive 8.6gigawatts, 8 times larger than Tesla’s Nevada Gigafactory – so there’s plenty of room to grow.

Battery Test Centre have a live feed of a B-Box hooked up to a SMA Sunny Island Inverter and it’s performing very well so far – click here to view the feed and see what real-life application of the battery looks like. The B-Box 25 (2.45kWh usable) they’re using has a DOD (depth of discharge) of 95.7% and a BMS (battery management system) to ensure it remains safe when charging/discharging. The battery is showing 97%+ efficiency. 

The B-Box differs from ‘conventional’ lithium ion batteries (such as the Powerwall) as it uses LFP technology – lithium iron phosphate (LiFePO 4) battery  – a rechargable lithium-ion battery, which uses LiFePO 4 as a cathode material, and a graphitic carbon electrode with a metallic current collector grid as the anode. This is widely recognised as a safer technology than lithium-ion which was built for smaller devices like mobile phones or mp3 players.

BYD in 2021 – Electric Car BYD EA1

I know this isn’t technically related to the BYD B-Box, but I love this news so much I thought I’d share:

BYD has revealed a revolutionary new electric hatchback with a 1000 kilometre range and sub 3.0-second acceleration that will be sold in Australia.

Revealed at the 2021 Shanghai Motor Show, the BYD EA1 hatchback rides on the brand’s new e-Platform 3.0 and receives power from the new 800-volt “Blade” battery claimed to be capable of receiving 150km worth of charge every five minutes.

No word on price yet but I’m confident it’s going to be very competitively priced! Wonder what battery they’ll have in them? 🙂
