Send the factory enough to design to: the application and duty cycle, voltage window and energy, continuous and peak current, charging method, physical envelope and mounting, operating temperatures, communication needs, target certifications and markets, annual volume and commercial terms. Separate

It isn’t automatically a fault. LiFePO4 cells stay close together through the flat middle of their charge curve and then separate at the top, where voltage rises steeply. The first cell to get there shows higher. It becomes a concern when the spread grows over several charge cycles, when charging re

Don’t connect them straight away. Small differences on arrival are normal, because batteries are usually shipped part-charged. But paralleling batteries at different states of charge causes current to flow between them and leaves the bank out of balance from the start. Charge each battery fully on i

The headline only tells you the voltage class and capacity. Price gaps usually come from lines that are easy to skip: the actual nominal voltage and energy, the BMS continuous current, the conditions behind the cycle-life figure, the enclosure and IP rating, communication and display options, certif

Start with the communication path, not the battery cells. Most of these faults come from one of four things: the cable is in the wrong port, the pinout doesn’t match, the protocol selected on the inverter doesn’t match the battery, or the master battery’s address or DIP setting is wrong. Check those

Often, yes. When a cart cuts out under hill load and recovers after a rest, the BMS has most likely tripped over-current protection. It can also trip on low cell voltage when one cell sags under load. That is not proof the battery is defective. It usually means the pack’s continuous discharge rating
