Will the battery still be over-discharged with BMS

Yes, a Battery Management System (BMS) does stop charging once the battery is full. The BMS is responsible for monitoring and managing the battery’s charge cycle to ensure it does not overcharge, which could lead to damage or reduce the lifespan of the battery. 1) disconnect the BMS and loads completely from the battery for long term non-usage. 2) use the remote switch to disable BMS (= using BMS''s LB path to cut out loads) and rely on your solar to supply the 5mA BMS operating current (the spec sheet says it draws 5mA when "off" but still connected). 3) disconnect all loads but leave BMS + solar ...

Does a BMS prevent overcharging?

One key aspect of a BMS is its ability to prevent overcharging. Overcharging occurs when you continue to supply power to a fully charged battery, pushing too much current into it beyond its capacity.

Why do you need a battery management system (BMS)?

Overcharging can cause irreversible damage to batteries, leading to reduced capacity or even complete failure. With a BMS in place, it continuously monitors the voltage and ensures that it stays within safe limits. Furthermore, a BMS also helps balance individual cells within a battery pack.

Is BMS good for lithium ion batteries?

While it’s true that BMS technology is commonly used in lithium-ion batteries, it can also be beneficial for other battery types such as lead-acid or nickel-based batteries. Regardless of the battery chemistry, overcharging can still occur and cause damage. 2. “BMS prevents overcharging by simply cutting off power.”
