At higher temperature the capacity will be reduced and constant exposure will cause increasing capacity fade.
At lower temperature the impedance will be higher reducing efficiency of charging and discharging.
The BMS will protect the system from short term over temperature and low temperature operations but the installation must keep the batteries within the recommended temperature.

A The important factors are to match;
· the battery pack voltage and system minimum and maximum voltages.
· the battery capacity in Amp hours needs to be matched with nominal current consumption and run-time.
· the system peak discharge current must be carefully matched to battery specification and if necessary a larger capacity pack chosen to prevent overheating.
· the total weight and dimensions also need to balance with these overall factors.

A No, chargers need to be suitable for lithium. Higher capacity batteries can also create higher currents, which emphasize the need of thicker cables.

A No, please refrain in just using one battery type per system.
