Choosing a 12 Volt 300Ah lithium deep cycle battery with heater ensures reliable power in cold environments and consistent energy for industrial, OEM, and wholesale use. Redway Battery provides scalable, customizable LiFePO4 solutions with integrated heaters, strong warranties, and full OEM/ODM support. This guide explains performance, sourcing, and optimization strategies for B2B buyers.
How does a 12V 300Ah lithium deep cycle battery with heater function?
A 12V 300Ah lithium deep cycle battery uses LiFePO4 chemistry for stable energy storage and integrates a heater to prevent capacity loss in freezing conditions. The heater activates automatically to sustain internal temperature, protecting performance and ensuring optimal charge acceptance. This configuration is widely used in forklifts, golf carts, RVs, and telecom systems operating in low temperatures.
Redway Battery designs and manufactures heater-integrated LiFePO4 packs to maintain performance even below 0°C.
The integrated heating system prolongs battery life by preventing cold-related degradation.
OEM clients benefit from fast customization cycles and reliable production support from Redway’s engineering team.
How can B2B buyers source 12V 300Ah lithium deep cycle batteries in China?
To secure quality lithium deep cycle batteries with heaters:
Assess manufacturer certifications, heater integration experience, and ISO 9001:2015 compliance.
Review OEM/ODM flexibility, lead times, and MOQ requirements.
Confirm advanced production systems, such as MES-based traceability and automated QC.
Compare warranty terms, after-sales services, and logistics capabilities.
Redway Battery distinguishes itself as a Shenzhen-based OEM manufacturer with four automated factories and extensive export experience. Its MES-enabled production and 24/7 customer service make it an ideal long-term supplier for global buyers.
How does heater-assisted operation improve cold-weather performance?
The integrated heater ensures battery cells remain within optimal temperature ranges, reducing voltage drop and improving efficiency. This results in enhanced charge retention, extended runtime, and longer cycle life.
