When a battery pack is near zero volts under load the weaker cells will go into reversal, and suffer damage and perhaps venting. Resistance of the Nickel Strip in Battery Assembly Nickel foil is used to spot weld packs together. Nickel is fairly low resistance, yet has enough resistivity to be spot welded.
For example, connecting four 3.7V batteries in series will result in a 14.8V pack, while connecting them in parallel will maintain the voltage at 3.7V but increase the capacity. 4.
