Battery Pack Welding | Battery Tab Welding

Voltage feedback is the typical mode of choice when welding battery packs, but the IPB-5000A can also weld in "combo mode" (current and voltage) to address even the most challenging battery welding applications. It is capable of a maximum output of 6000 amps, making it ideal for welding thicker tabs. Safety is another concern when selecting resistance welding equipment

18650 battery pack

I am trying to find a good way to remove (quite thick/strong welds) nickel strip from 18650 battery packs without damaging the 18650 cells...and having a relatively flat surface (on the cell''s terminals) in order to be able to properly weld on new nickel strip in the future.. The nickel strip on the battery packs I have is approx 0.3mm thick and is nickel-coated steel strip.

Is there a way to secure an 18650 battery pack together without

Constructing battery packs without hard mechanical connections is usually a very bad idea. Or worse. In some cases the environment may not be hostile BUT an ebike is not such an environment. 40A is at least 10S2P for any 18650s. (If you know of any manufacturer rated 40A discharge 18650s please point me to them - I''d be genuinely interested).

I''m guessing, it''s possible to disconnect the cells while still in-pack, and then insulate them, so the pack doesn''t need disassembly, and you can then test them for resistance and charge using a clamp, and voltage, and capacity, and without removing them, reweld them back in place if they test ok. Bad cells can then be cut out normally, or simply left insulated (disconnected),

6 FAQs about [How to replace the battery pack without welding]

Should I Build A LiFePO4 battery pack?

After reading around I decided I want to build a LiFePo4 battery pack, mainly because it's more chemically stable and heavier (I actually need the weight). The battery format 18650 seems to be the most standard, so it seems logical to go for that. As far as I understand I need a spot welder to connect the batteries together.

How do I know if a battery pack is bad?

These 13 packs were then connected in Series with the positive of one pack connected to the negative to another. Use an electrical meter to test every cell grouping to see what the voltage is. I usually write the bad cell voltages on the side of the batteries that have failed.

Should I use a 25R or 26F battery pack?

If you chose to replace batteries in your pack with a different kind of lithium battery (not recommended) you should use packs that are similar in capacity and power capability as the cells you are replacing. I used 25R cells because it was what was easy for me to get my hands on and they only have 100MaH more capacity than the 26F cells.

How do you solder a positive wire to a pack?

When you are connecting the large ground or positive wires to the pack you can try to solder them to the nickel strips on the pack or you can solder them to a scrap of nickel strip and then spot weld that strip to the pack.

What should I do if my battery is corroded?

If there are cells that are physically damaged or badly corroded you may want to stop what you’re doing and just send the pack away to be recycled. If the battery starts producing smoke then the correct course of action is to bury it in sand outside for 30 days out of the rain, then dig it up and recycle it.

Can a cell pack be glued together?

If the cells are hot glue gunned together then it will probably be impossible to get the pack apart to replace the dead cells. If the pack is glued together you can leave the existing cells inside the pack as dead weight and add new cells to the outside of the pack and reroute the cabling. Although this sounds pretty complicated it’s really not.
