Features
High safety design
In terms of battery safety, our products ensure the safety of users through multiple safety protection measures. These safety measures include short circuit protection, overvoltage protection, overcurrent protection, temperature monitoring, etc.
Wide operating temperature range
The operating temperature range of our products is usually between -20°C and 60°C, which enables it to operate stably in extreme environments. Especially in high or low temperature environments, the battery's built-in thermal management system (such as liquid cooling or air cooling system) can effectively regulate the battery temperature to avoid performance degradation caused by overheating or overcooling.
Fast charging and discharging
The ESS Battery Pack perform well during charging and discharging. Normally, the charging efficiency of ESS battery packs can reach more than 95%, and the discharge efficiency can be stabilized at more than 90%.
Long life cycle
The cycle life of our products far exceeds that of traditional batteries, generally reaching more than 3,000 times, and the life of some products can be extended to 5,000 times. In contrast, the cycle life of lead-acid batteries is usually between 500-1,000 times.
