Direct Communication

Pylontech RT12100 12.8V 100Ah 1280Wh Lithium Iron Phosphate (LiFePO4) IP67 Battery with RS485 / CAN / Bluetooth and Dry Contact Communications communicates directly with Victron CerboGX, eliminating the need for a BMV-712 or SmartShunt, and providing accurate State of Charge.

Small footprint, high performance  

Compared to lead-acid batteries with the same capacity, the Pylontech RT12100 offers twice the usable capacity and more than three times the life cycle, with only 40% of the weight. (Dimensions: L 12.8 in x W 6.8 in x H 8.9 in, Weight: 28 lb). 

Waterproof casing

Rugged IP67 enclosure offers protection against dust, water, and liquids, up to and including immersion in up to one meter of water. 

Built-in heater

Below zero temps will damage lithium batteries. Switched on manually, via the app, or with a relay, this battery's built-in heater is a significant value-add for vehicles and portable power storage units operating in environments as cold as -4°F and or left in storage at as low as -40°F. 

Outstanding BMS

Unlike many competitors who merely assemble batteries from components made by different manufacturers, Pylontech manufactures its battery cells and the battery management system (BMS). Pylontech's internal BMS carefully monitors and wisely manages the charging/discharging process to ensure cell balancing and prevent damage due to overcharge, over-discharge, overcurrent, temperature, or short circuit. 

Expandable up to 4 in series and 4 in parallel

this battery's embedded BMS allows for seamless networking of up to 16 Pylontech 12V batteries to create a 48V 400Ah battery bank.
