How do I assemble a 48V lithium iron phosphate battery pack by myself?
step:
①Disassemble the battery pack, measure the internal resistance of each battery cell, re-pair; spot welding, reassemble the battery pack.
②Calculate the distance according to the hole, and cut the insulating board.
③After installing the screws, please use flange nuts to prevent the nut from falling off. After the screws are connected, the lithium iron phosphate battery pack can be fixed.
④When connecting and soldering the wire and connecting the voltage collection wire (equalization wire), do not connect the protection board to avoid accidental burnout of the protection board.
⑤Place the protective board, and then package the battery as a whole.
⑥Fasten the entire battery pack with an insulating plate and seal it with nylon tape.
⑦The final packaging is completed, and the output and input are all silicone wires.
Tools needed: electric grinder (stainless steel saw blade, small grinding wheel, sandpaper), needle-nose pliers, multimeter, internal resistance meter, large reservoir capacitor spot welding machine, T12 soldering station.
Required consumables: nickel tape, gold finger high temperature tape, cloth tape, barley paper, heat shrinkable film, wires, XH2.54 terminal line.

What problems should be paid attention to when assembling lithium iron phosphate battery pack?
1. It is necessary to assemble a satisfactory lithium iron phosphate battery pack, select a good quality and reliable lithium iron phosphate battery, and have a sophisticated lithium battery equalization protection board. At present, the protection boards on the market are uneven, and there are also analog batteries. It is difficult to distinguish, it is better to choose the digital circuit control, for example, the energy storage electric is good.
2. It is possible to know a certain technology, because to choose the right battery block, the internal resistance and the like should not be too large, and the parameters should not be too different.
3. Consider the selection of the charging board. If there is no certain foundation, it is not recommended to try, there is a danger of explosion.
4. The lithium battery pack should be waterproof and insulated, and the batteries should be neatly arranged to facilitate future maintenance.
5. After using the newly assembled lithium battery pack for a period of time, check the battery voltage in groups, the internal resistance of the battery before welding, and the current voltage error should not exceed 0.05V to prevent overshoot and overdischarge.
what are the materials used to assemble lithium iron phosphate batteries?
General lithium battery materials include electrolyte, CMC, lithium cobalt oxide, separator, PVDF, high temperature adhesive tape, NMP, graphite anode, SBR, oxalic acid, copper foil, aluminum foil, etc. These are the constituent materials of lithium iron phosphate batteries.
