How long will my Lifepo4 BATTERY Packs Last?

-High Energy Density , from Laboratory testing, it can  theoretical reach a capacity of 180mah/g and mass production capacity as high as 165mah/g.
-10x Longer Life span     In comparison with lipo battery which has a cycle life of 500 or 1000 cycles, LiFePO4 battery can extends its battery life up to 3000-5000 cycles.
-High temperature performance, since lifepo4 batteries are mostly used for solar storage, street light, mobile satellite station, Ebike or even EV Car, so it's very important to have chemicals that can endure high temperature, for LiFePO4 battery, it can have  High thermal stability of phases up to 500C.

LiFePo4 batteries are considered to be safe, non-flammable and non-hazardous by international regulated standards among all kind of lithium battery packs

For Battery packs that contains too many battery cells, since battery cells voltage and capacity is not performing the same all the time, that's why BMS comes out. A BMS is a simple electronics system to measure and control voltage and current. and it will stop charging when the desired voltage is reached.

For example, in 10 cells pack, some battery cell may reach its full capacity already, while others might only 80% full. In case battery cell are already charged full, the BMS will shut down the power flow, in case there is no BMS, the already fulled charged battery cell will go on with the charging and thus will short its life or even cause heat or fire.

Some BMS can even monitor many factors such as temperature,humid,etc.. some can even send data to computer or App, so people can read the data on time.
