I'm thinking about 4x 330ah smart batteries for a 48V system. I understand they all have internal cell balancing. plan to use lynx smart bms.
someone tell me if I still need to add 3x balancers to balance the overall battery V between each smart battery? I cannot find an answer... or will the batteries balance out as a whole because the cells will balance out internally?
thanks
nobody has an answer?
@mrbart As per the LBS manual
A 2-hour fixed absorption period is recommended for lithium batteries so that there is enough time for cell balancing to take place. It is important to regularly fully charge the battery. This so the battery spends enough time in the absorption stage. A full charge once a month should be sufficient. However, there are some applications where the cells will become unbalanced quicker than usual. This is the case when the system is used more intensively or if the battery bank consists of multiple batteries in series. To ensure a well-balanced battery, a weekly full charge is required for:
Systems with a battery bank that contains batteries that are connected in series.
Systems that are charged/discharged every day or a few times per week.
Systems that have high discharge currents.
Systems that have short charge periods or low charge voltages.
If you fully charge your batteries at least weekly, balancers would not be mandatory.
Do remember to fully charge each battery before connecting in series.
