You can waterproof other shapes of batteries too, the main thing is to take care to keep the contacts clean while you seal all the gaps. you might need to put some tape over the contacts (cut to shape with a knife), then apply the waterproofer, then peel off the tape after it is dry. Did you make this project? Share it with us!
The fundamental is very simple: Just to combined the number of LiFePo4 cells in series and parallel to make a bigger pack and finally to ensure safety by adding a BMS to it. The LiFePo4 cells come in a variety of sizes, but here I have used the 32650 type. My Book : DIY Off-Grid Solar Power for Everyone
To make the battery pack, you have to first finalize the nominal voltage and capacity of the pack. Either it will be in terms of Volt, mAh/ Ah, or Wh. You have to connect the cells in parallel to reach the desired capacity (mAh ) and connect such parallel group in series to achieve the nominal voltage (Volt ).
Any short circuit in the battery pack may lead to the catching of fire and explosion. First, add a layer of insulating Barley Paper over the top and bottom side of the battery pack. Barley Paper is pure cellulose with high electrical insulation properties that have made it possible to use them for the making of portable lithium-ion battery packs.
Lithium-ion batteries have become a go-to option for energy storage in solar systems, but technology has advanced, a new winner in the race for energy storage solutions has emerged: lithium iron phosphate batteries (LiFePO4).
To make the battery pack, you have to connect the 18650 cells together by means of Nickel strips or thick wire. Generally, Nickel strips are widely used for this. In general two types of nickel, strips are available in the market: nickel-plated steel strips and pure nickel strips. I will suggest buying a pure nickel.
