Building High Capacity 32650 Lifepo4 Battery Pack for emergency or daily use - 12V - 24Ah #1

This is my 12V-24Ah 32650 Lifepo4 Battery Pack for emergency or daily use with 30A BMS. After finished, I decided to reduce the battery capacity from 24Ah to 18Ah to have more space to add a quick charge circuit for the phone and a 20W LED light for emergency use (Part 2).

Cell voltage
Minimum discharge voltage = 2.5 V
Working voltage = 3.0 ~ 3.2 V
Maximum charge voltage = 3.65 V

The lithium iron phosphate battery (LiFePO4 battery) or LFP battery (lithium ferrophosphate), is a type of rechargeable battery, specifically a lithium-ion battery, using LiFePO4 as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. LFP chemistry offers a longer cycle life than other lithium-ion approaches.
Because of the nominal 3.2 V output, four cells can be placed in series for a nominal voltage of 12.8 V. This comes close to the nominal voltage of six-cell lead-acid batteries. Along with the good safety characteristics of LFP batteries, this makes LFP a good potential replacement for lead-acid batteries in applications such as automotive and solar applications, provided the charging systems are adapted not to damage the LFP cells through excessive charging voltages (beyond 3.6 volts DC per cell while under charge), temperature-based voltage compensation, equalisation attempts or continuous trickle charging. The LFP cells must be at least balanced initially before the pack is assembled and a protection system also needs to be implemented to ensure no cell can be discharged below a voltage of 2.5 V
Compared to other lithium chemistries, LFP experiences much slower degradation when stored in a fully charged state. This makes LFP a good choice for standby use.
