How to choose a quality storage battery: Just think of an onion

Layer 1: The chemistry

This is perhaps one of the most crucial elements. If the chemistry inside the battery is not right, it will not only be ineffective, but dangerous as well. Different chemistries are better suited for specific environments. For instance, automotive grade battery cells deliver extreme temperature resilience and high energy density, which makes them well-suited to environments that rely on these characteristics.

Layer 2: Charging capacity

Once you are satisfied with the chemistry, you need to ensure that the battery chosen has the right capacity insurance. This is to provide the ability to support the charging required and remain within the 48-volt paradigm critical for renewable energy.

Layer 3: Well-designed box

The battery cells must obviously be of the highest grade. The chemistry means little if the battery is not constructed correctly. The physical box must be rugged while the connections to the cells for monitoring and power delivery must be solid. The battery must have a well-designed box that can take shocks.

Layer 4: Safety

The final part is ensuring the battery does not leak or explode. The safety specification of the battery you choose is an important consideration. Chemical devices need to be designed and stored correctly as this speaks directly to their safety.

A lithium battery, for instance, features a battery management system (BMS) that monitors and shuts down the battery if something goes wrong. There are also physical signs to check out as well such as whether the battery is misshapen or has water marks on it.
