Serial-parallel correct connection of battery cells.
We certainly do not recommend connecting two „strings“ together at the high DC level. The LiFePO4 cells have very small internal resistance and connecting cells at high level voltage (e.g. one pack is 53V, the other pack is just 48V) will cause extreme currents that may cause damage to the ce

Safety of work when installing batteries
We use insulated tools when working with the battery.
Always secure hand tools to avoid short-circuiting the battery in the event of careless handling or accident.
An unwanted short circuit when installing the battery is the most common cause of cell damage.
An example ofself-made insulated tools can be
