When a lead-acid battery’s display is used with a lithium‑ion battery, the state-of-charge reading is inaccurate. The root cause lies in the fundamental differences between the two battery types in terms of voltage characteristics, state-of-charge measurement principles, and system design. A detailed analysis follows:

Is active balancing on a BMS protection board necessarily better than passive balancing?
In battery management systems (BMS), active balancing and passive balancing are two distinct strategies for equalizing the state of charge across a battery pack, each with its own advantages and disadvantages. Active balancing is not necessarily superior to passive balancing in all scenarios; rather, the choice between the two should be carefully weighed based on specific application requirements, cost considerations, and system complexity.

What are the categories of reliability testing?
Reliability testing is conducted to evaluate a product’s ability to perform its specified functions under defined conditions and within a prescribed time frame. Such tests can be classified in various ways, primarily based on factors such as the test objective, environmental conditions, and the stage of implementation. The following are common classification schemes and their specific types:
