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.

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 mentioned, Pytes' Australian agent and registered importer is K2 Battery Pty Ltd. Based in Redland Drive Mitcham, Victoria, K2 designs batteries for mobile and specialty applications; exclusively using LFP chemistry.

Comprised of lithium iron phosphate (LFP) cells, each module has a nominal energy capacity of 5.12kWh (recommended maximum depth of discharge is 90%) and a usable capacity of 4.6 kWh is noted in the CEC listing. Up to 96 units can be connected in parallel, using Pytes’ “Hub and Group” architecture for a maximum capacity of a whopping 492 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.
Pytes have also applied for (but is still waiting) for CEC listing of other ESS products; including the PiLV1 stackable battery and the higher power V5 Alpha Plus.
