Polinovel lithium iron phosphate batteries have many uses and are commonly used in golf carts, mobility vehicles, solar energy storage, automated guided vehicle (AGV), automotive, marine, boat, medical devices, telecommunication, and much more. The performance of our LFP battery is good. It is often employed in energy storage and driving traction that require a long lifespan and a good level of safety.

Polinovel lifepo4 batteries adopt durable internal structures to ensure they are suitable for the toughest conditions, such as high charge and discharge currents, humid environments, and mechanical shocks or vibrations. These lithium-ion batteries are well-defined performance, long-term stability, are keeping efficiency, last much longer than conventional batteries, giving you peace of mind and saving time and money on maintenance and replacements.

Polinovel batteries power and charging various general purpose and instrumentation equipment. The scope for using lithium iron phosphate batteries in a wide range of applications is limited only by your imagination. Here just included a part of the applications for your reference. If you can’t find your required application, get in touch to discuss your specific requirements.
