+ | Lithium battery banks are lighter and have higher energy density than lead-acid batteries. | ||
+ | |||
+ | |||
+ | Lithium banks come in three main forms: | ||
+ | * " | ||
+ | * DIY banks, often " | ||
+ | * manufactured complete banks that do not mimic the physical shape of lead batteries | ||
+ | |||
+ | ==== BMS ==== | ||
+ | Because of the very high energy density and sensitivity to temperature and voltage extremes, most Li banks are equipped with a Battery Management System (BMS) which monitors and controls the bank and the cells in it. | ||
+ | |||
+ | Depending on the BMS, features may include: | ||
+ | * protection from overcharging individual cells | ||
+ | * "top balancing" | ||
+ | * protection from over-discharge | ||
+ | * protection from excess current in charging and/or discharging | ||
+ | * prevention of charging when temps are too low((typically freezing or below) | ||
