| Apr 6 at 9:12 | comment | added | SA A | @winny Can you draw a schematic (related to my schematic) to show how the ideal case (6.7 CC-CV power supply) can be included in my circuit? | |

| Apr 2 at 19:20 | comment | added | winny | Without a Zener clamp or some shunt or pass transistor, it won’t be regulated, but adding diodes would perhaps make it good enough. The ideal case would be a 6.7 CC-CV power supply. | |

| Apr 2 at 17:22 | comment | added | pipe | Voting to close because the circuit is obviously not as described, LED1 could never light up. That makes me think more things could be wrong, and everyone's just chasing ghosts. Maybe a good photo of the board could help. | |

| Apr 2 at 17:03 | comment | added | SA A | Yes it passes 7.2 volts (2.40 for each cell) and causes battery gassing. Using diodes to drop voltage, will not give constant 6.80 volts. | |
| Apr 2 at 16:57 | comment | added | winny | Oh, lead-acid. I somehow read NiCd or NiMH. Is it slowly boiling off the battery? Stack more diodes in series with D1 to drop off some volage? | |

| Apr 2 at 16:44 | comment | added | SA A | @ winny The problem I am trying to solve is that the closed circuit voltage goes beyond 6.80 volts; I want to prevent it from going beyond 6.80 volts. | |
| Apr 2 at 16:41 | comment | added | SA A | @Spehro 'speff' Pefhany What I see is that LED1 lights up when I plug the appliance. | |
| Apr 2 at 16:37 | comment | added | winny | If the battery is rather large, it will clamp the voltage to lower than the open circuit voltage. What's the problem you are trying to solve? | |
| Apr 2 at 16:36 | comment | added | Spehro 'speff' Pefhany | Seems unlikely that LED1 will ever light with a direct short across it. | |
| Apr 2 at 16:34 | comment | added | SA A | @greybeard On the circuit board, it is a trace that is connected to 2 resistors in the florescent bulbs' circuit. | |
