I normally build 11 plate dry cell with great gas production.
I recently built a 6" x 6" 6 plate dry cell but only producing 10 amps max even though I added another teaspoon of KOH. This has been monitored for 2 days.
The previous dry cell was an 11 plate dry cell and used a PWM to control to 15 amps.

Don't understand this as the config on the 11 plate are +NNNN-NNNN+ (one side of positive on each plate using blind gasket & both side of negative plate) and the 6 plate cell are +NNNN- (using both sides of the NEG & POS plates)

Is this normal ?

Any advice appreciated
