Pytes V5 5.12kWh 51.2V 100Ah Lithium Iron Phosphate Battery
The Pytes V5 LFP Battery is an innovative lithium iron phosphate (LFP) battery designed for optimal home energy storage. Featuring a safe, high-performance 51.2V, 100Ah capacity that delivers 5.12kWh of energy, this compact and maintenance-free battery bank is ideal for a range of applications from residential to industrial systems. The battery is easy to install, requires no upkeep, and supports parallel assembly for expanded capacity. Its key features include a self-heating function to facilitate charging in cold climates and a robust 100A maximum continuous charge/discharge rate. Up to 16 batteries can be stacked without the need for a Pytes Energy Hub.
As a 48V server rack battery, the V5 slots into new or existing solar systems and pairs with leading hybrid inverters through CAN or RS485 communication.
How the Pytes V5 Self-Heating Function Works
Integrated Heating in Pytes V5 - Here's how it functions: The battery's heating system is solely powered by the charging source, such as an inverter or charge controller, consuming up to 180W per battery. It efficiently heats the battery at a rate of up to 10°C per hour within an operational range of -4°F to 50°F (-20°C to 10°C). The heating initiates when temperatures drop below 41°F (5°C), raising the temperature to 50°F (10°C). For temperatures between 35°F and 41°F (2°C and 5°C), the heater activates and charges simultaneously until it reaches 50°F, then ceases heating while continuing to charge. Below 35°F (<2°C), heating takes precedence until the battery warms above 41°F, after which it resumes normal charging. This system does not impact the battery's state of charge (SOC).
Server Rack Installation Requirements
The V5 battery requires 4U or 7" of space for each unit to ensure proper busing and adequate cooling. For instance, installing three batteries would necessitate a 12U server rack.

Pytes V5 vs E-BOX-48100R: The Next-Generation LiFePO4 Battery
PYTES Energy V5° LFP Battery 5.12kW 100Ah 48VDC LiFePO4 Self-Heating. The new V5° lithium phosphate battery is the latest in home energy storage and the next generation after the venerable E-BOX-48100R model. The V5 provides a safe, well-designed, and high-performing battery bank solution. The battery pack is compact, easy to install, maintenance-free, and can be assembled in parallel when adding more capacity. It has wide applications including residential, small commercial, industrial, and telecom systems.
The big brother to the E-BOX-48100R LFP Battery, the new V5° LiFePO4 battery also provides self-heating that auto-starts in cold environments and facilitates charging below freezing temperatures. The new V5° LiFePO4 battery also has a higher 100A Maximum Continuous Charge/Discharge rate.
What's New in the Pytes V5
- Updated State-of-Charge Indicator
- Phoenix terminals with busbar connections that have higher ampacity instead of the previous wire cables used on the E-BOX-48100R
- Smaller and lighter than the E-BOX-48100R
- Continuous charge/discharge rate of 75A which can be increased to 100A with a firmware update
- BMS includes overcurrent alarm and Short Circuit Protection
- Built-in 320A fuse in each V5 battery
- The built-in heating pad automatically activates when the BMS senses that the ambient cell temperature falls below 41°F. The heating pad will remain on until the temperature reaches 50°F. The heating pad will not work in temperatures below -4°F. If auto activation of the heating pad does not result in a change in temperature after 30 minutes, an alarm will trigger.
- With the optional WiFi Dongle, you can have real-time monitoring, remote upgrading, and alarm notification of your battery bank system on your computer, tablet, or mobile phone.

Frequently Asked Questions
Can I mix the PYTES V5° battery with the PYTES E-BOX-48100R battery in the same battery bank?
No, these batteries cannot be mixed in the same battery bank. They would have to be separate battery banks.
How fast does the heater work?
The temperature rises an average of 10 degrees per hour after the internal heating pad is turned on.
How much power does the internal heating pad use?
The built-in heating pad uses 170W of power while in use.
Is the Pytes V5 a 48V battery?
Yes. The V5 has a nominal voltage of 51.2V, which is the standard for 48V lithium (LiFePO4) batteries. So it works with any 48V hybrid inverter or charge controller that supports lithium batteries.
Can the Pytes V5 charge in freezing temperatures?
Yes. The built-in heater activates automatically below 41°F and warms the cells before charging. It works down to -4°F, so the V5 keeps charging through cold winters in garages, sheds and unheated rooms.
How many Pytes V5 batteries do I need?
Each V5 stores 5.12kWh. Two batteries give you 10.24kWh for essential-load backup, three give you 15.36kWh, and four give you 20.48kWh for whole-home backup. Remember to allow 4U of rack space per battery, so three batteries need a 12U rack.
Which inverters are compatible with the Pytes V5?
The V5 supports closed-loop CAN and RS485 communication with most mainstream 48V hybrid inverters, including Sol-Ark. Contact the Liniotech team to confirm compatibility with your inverter model and firmware.
How long does the Pytes V5 battery last?
The V5 is rated for 6,000+ cycles at 90% depth of discharge, with a calendar life of 10+ years. It also carries a 10-year limited manufacturer warranty.
What is the difference between the Pytes V5 and the Pytes V16?
The V5 is a 5.12kWh server rack battery for modular indoor banks. The Pytes V16 is a 16kWh wall or floor-mounted battery with an IP66 outdoor-rated enclosure. Choose the V5 to build capacity in small steps, or the V16 for maximum storage with fewer units.
