Create 14.4V energy storage battery pack

To create a 14.4V energy storage battery pack as a replacement for lead-acid batteries using 33140 lithium iron phosphate batteries, follow these steps. The 33140 lithium iron phosphate batteries have a similar fully charged voltage to lead-acid batteries but are safer. Each 33140 cell has a capacity of 15AH, which is four times higher than the best 18650 batteries, and it's only slightly larger in size than two 18650 batteries. These cells can be discharged over 1000 times, making them an excellent choice for energy storage and electric vehicle battery packs.
First, connect the four cells in series using nickel steel strips. Next, weld the battery charge and discharge protection board to the cells. Apply insulation above the batteries, securing it with adhesive tape. Finally, encase the batteries in heat shrink tubing to complete the battery assembly.#DIY #lithiumbattery #lithiumbatterypack #lifepo4battery #batterypack #energystoragebattery #energystorage
