| Jan 30, 2022 at 9:17 | comment | added | Alex | @Drew lack of electrical knowledge was what led me to the point of buying a 2A smart charger, which didn't work, and then nearly a 10A smart charger, which probably will not work. I will be looking for a dumb charger. Thank you all of you for your advice. | |

You can even buy croc clips with a screw terminal on the back to attach a wire. Just get some electrical tape and a pair of wire strippers and wing it, you'll figure it out. | |
| Jan 30, 2022 at 8:44 | comment | added | Alex | @Drew I cannot find a 12V supply which outputs to crocodile clamps, are these readily available? The motor was modified to turn a heavy rotisserie, the total weight is probably about 6 kgs. | |

It won't need to supply 10A since the motor won't draw that unless it has a heavy load. You'll probably need more like 3A. | |
| Jan 30, 2022 at 8:17 | comment | added | Alex | @SolarMike I do not understand your comment, do you mean I should attach my smart charger to a battery and then run crocodile clips from the battery to my windscreen wiper motor? | |
| Jan 30, 2022 at 8:14 | comment | added | Solar Mike | So get a battery to go with the smart charger. Battery size depends on run time… | |
| Jan 30, 2022 at 8:13 | comment | added | Solar Mike | Cheaper probably because they don’t use a big transformer and components used are cheap so they don’t last long. | |
| Jan 30, 2022 at 8:08 | comment | added | Alex | thanks @Neil_UK that is what I suspect. So why is it that all the smart battery chargers are much cheaper than the the battery charger that can be a power supply? | |
| Jan 30, 2022 at 7:32 | comment | added | Neil_UK | It sounds like you need a power supply rather than a battery charger. A smart battery charger expects to find a battery at the end of its leads. If it doesn't behave like a battery, then the charger may shut down to avoid damaging the battery. An old style battery charger was dumb, more like a power supply. | |
