Finn's Pytes Energy Batteries Review & Verdict
Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO
There's nothing on the Pytes Energy Australian website except boilerplate text from the design template being used for it - not a great way to make a good first impression. Thankfully, the Pytes international site is better.
But with these batteries being very new in Australia and in the absence of trusted feedback, I can't recommend them (or otherwise) at this point. Something I will flag is the warranty precondition regarding ambient temperature - which is a maximum of 45°C.
Pytes Energy Batteries: Pros & Cons
- Lack of track record in Australia
- Maximum ambient temperature during operation under warranty is 45°C

Company Info
Pytes Energy was founded under the name of DLG (Shanghai) Electronic Technology Co., Ltd. In 2006 it began offering battery solutions for consumer electronics, and in 2007 its e-bike division was founded. That was followed by establishing a vacuum division in 2014 and the company began making batteries for medical equipment in 2015.
Its energy storage system (ESS) division was founded in 2018 and the company's Shandong, China factory commenced production. Its first battery was the Ebox-48100R, designed for home, small commercial, telco and industrial energy applications.
In 2019, the company renamed to Pytes Energy.
In 2022, Pytes' E-box battery received UL 9540 certification, which provides a basis for energy storage system safety that includes reference to important technology safety standards and codes. In 2024, Pytes Energy launched its high voltage HV48100 battery.
As for Astrum Energy, it is based in Sydney - but past that we can't tell you much as their website (which also happens to be the Pytes' Australian website) is a bit of a mess.
About The E-Box 48100R
The E-Box 48100R is a rack mounted battery solution that has been approved by Australia's Clean Energy Council.
Comprised of lithium iron phosphate (LFP) cells, each module has a nominal energy capacity of 5.12kWh (recommended maximum depth of discharge is 90%). Up to 48 units can be connected in parallel for a maximum capacity of a whopping 245.76 kWh.
The E-Box 48100R's operating temperature range is discharge: -10 ~ 50°C and charge: 0 ~ 50°C (but see notes below on warranty). It has a nominal voltage of 51.2 V and a voltage range of 47.5 V - 57.6 V. Module dimensions are: L: 440mm x W: 620mm x H: 117mm, and the E-Box 48100R's weight is 51 kg.
Warranty Details
The E-Box 48100R's warranty covers 10 years or 6000 discharge cycles (or 26.1MWh of aggregate throughput) at 90% DoD, whichever comes first. One of the preconditions of the warranty is the ambient temperature during operation must not exceed 45°C - and in some parts of Australia it certainly reaches that.
