Too few cells and the voltage across each individual cell will be too high, and the water can reach boiling temperature.
Khim. Nauk 440(2), 1–4 (2011). Oxyhydrogen explosions can be a hazard where water electrolysis happens unintentionally, for example in large lead-acid batteries.
Avoiding oxyhydrogen explosions from gas formation in the battery. 4, 70 (2008). Fiz. Fiz. Degenerate explosion of oxyhydrogen gas at the third ignition limit initiated by the products of a heterogeneous reaction on an inactive catalyst (Quartz). The explosion is the result of accumulation and decay of the intermediate product in the gas, which is hydrogen peroxide produced mainly in the wall of the reactor. Khim., 80, No. 2 Citations.
 Although, if the gas velocity out of a torch tip is too great, there will be ignition difficulty as the flame will tend to blow itself out. 3, 282–291 (2006). When charging lead batteries such as traction batteries for forklift trucks, gas forms as the result of chemical reactions: the water inside the battery is electrolysed into hydrogen and oxygen. A.

Keeping the voltage at such a relatively low value will mitigate waste heat associated with an unnecessarily high electrolytic reaction temperature. Avoiding oxyhydrogen explosions from gas formation in the battery. B. V. Azatyan, V. A. Kalkanov, A. G. Merzhanov, and A. Margolis, M. A. Namoradze, and V. I. Sklyarenko, “Kinetics of the spontaneous chain initiation and catalytic conversion on magnesium oxide in the reaction of hydrogen with oxygen,” Kinet. The main criteria for common ducting is a single gas output hose. When ignited, this mixture combusts to water, making 142.35 kJ (34,116 gram calories) of heat for each gram of hydrogen burned: that is 286.97 kJ/mol of enthalpy. The explosion is the result of accumulation and decay of the intermediate product in the gas, which is hydrogen peroxide produced mainly in the wall of the reactor.

It is less hot when there is an excess of oxygen or hydrogen, or when an inert gas such as nitrogen is mixed in, because there the same amount of heat is added to a larger amount of matter.

Some water torch models mix the two gases immediately after production (instead of at the torch tip) making the gas mixture more accurate; this electrolyzer design is called common ducting.
