What Makes High Voltage LiPo Batteries Different?

LithoTop provides high voltage battery customization based on your product design, electrical requirements, charging system, and assembly space.

A standard LiPo battery is usually charged to 4.2V per cell, while a high voltage LiPo battery can be charged to 4.35V or 4.4V per cell, depending on the cell chemistry and project design.

This higher charge voltage allows the battery to store more energy in the same physical size, making it a strong choice for compact products where battery space cannot be enlarged.

Unlike high rate LiPo batteries that focus on large discharge current, high voltage LiPo batteries are mainly designed for higher energy density, longer runtime, and compact device design.

Avoiding Common LiHV Battery Mistakes

Decades of experience help us stop field failures. We intercept specification risks to keep your assets safe and your professional reputation intact.
● Common Mistake: Capacity Waste

Why use standard chargers for high voltage cells?

Standard 4.2V chargers leave 15% of your paid capacity unused. This kills your project runtime and your ROI.

Expert Advice

I mandate a 4.35V dedicated profile. Never trick old chargers. It leads to lithium plating and early cell death.

● Common Mistake: Space Planning

Why ignore the 5% expansion gap?

Cells expand during hard work. Tight mounts crush the internals and lead to shorts or equipment fires.

Expert Advice

Stop designing zero gap mounts. I recommend a 3mm air buffer to allow the battery to breathe under load.

● Common Mistake: Storage Decay

Why store high voltage packs at full charge?

Keeping LiHV at 4.35V during storage causes rapid chemical decay. Your internal resistance will spike within weeks.

Expert Advice

Move cells to 3.85V for storage. I recommend a storage charge policy to save your battery life and your budget.

Global Industrial Power Validation
