TommaTech Rack Series 51.2V 102Ah G2 Lithium Battery

The TommaTech Rack Series 51.2V 102Ah G2 is the rack-oriented version of the manufacturer's 51.2V G2 low-voltage lithium battery platform.

Electrically, it shares the core specification of the Modular G2 battery: 51.2V nominal voltage, 102Ah capacity, 5,222.4Wh published energy, 50A recommended charge and discharge current and 75A maximum charge and discharge current.

The major difference is mechanical construction. The Rack model uses model code BTR-P-51.2V-102Ah-R and measures 482 × 664.5 × 174.2mm, with a published weight of 53.35kg.

This physical architecture makes the product more suitable for projects where batteries are organized within a rack or cabinet arrangement.

Because enclosure geometry, rack compatibility, weight distribution, ventilation and service access differ from the standard Modular product, it should remain a separate CMS listing rather than being presented merely as a capacity variation.

Technical Architecture

The Rack model integrates the same 51.2V LFP electrical platform into a dedicated rack-oriented chassis.

Multiple identical units can operate in parallel while the system remains within the same nominal voltage architecture.

Intended Applications

• Battery rack installations
• Cabinet-integrated ESS
• Low-voltage solar storage
• Backup-power battery banks
• Commercial installations requiring organized battery-module mounting

Engineering and Selection Notes

In addition to electrical compatibility, verify:

• rack dimensions
• cabinet load capacity
• battery weight
• ventilation
• cable routing
• connector access
• maintenance clearances
• total number of rack modules

Important Technical Notes

The Rack Series should not be represented as unquestionably current until TommaTech confirms ongoing commercial availability.

Manufacturer confirmation required before quotation.
