Rechargeable Lithium

Certified Safety

Our lithium ion battery features a number of unique features to ensure absolute safety. We use a high-quality ceramic-coated polyethylene (PE) separator to act as a built-in shutdown method in the event of a fault; if the battery core reaches abnormal conditions, this durable PE layer melts down to block ion flow and chemical function throughout the battery. Each battery is also equipped with built-in vent that relieve internal pressure if it rises above normal levels. This stops the battery from reaching bursting point. Together, these and more safety-conscious design features ensure that the GP lithium-ion battery is absolutely safe.

Expansion Free

Each GP lithium-ion battery is made of the highest-quality steel via state-of-the-art automated production methods. Coupled with our innovative designs and built-in safety features, this ensures that our lithium-ion products do not expand or swell — they maintain their precise dimensions and consistent quality across their whole cycle life. This exceptional mechanical stability has been proven over hundreds of cycles — without even minimal expansion.

Quick to Charge

Our perfected lithium-ion battery design delivers fast charging, enabling engineers to incorporate fast-charge features into their products. The GP fast charge model has a step-charging profile and delivers a charging rate of 3C — we also offer a supreme model with a charging rate of up to 5C on request.
