Alright guys. I thought I would make a little video of the charging process of a bank of 6 2700 farad caps. Some people may be a little intimidated about the process, so I thought I would give them an idea both visually as well as with the meters so you can get an idea of what kind of current these things can draw when charging up.
Its really not as bad as some may think. Just make sure you have large enough wire to handle the current, don't try using some cheap under sized 10ga or you will probably melt it. Get some good 4ga or larger and you will be fine. Or do as I did and use some jumper cables.
I chose to use a small 35ah battery as you can see as my main source to bring them up to a decent voltage were the charger will handle it. As you can see in the video the intial current spike is 200A+(which is probably due to the batteries limited capacity, I have no doubt had I used a larger battery current draw would have been greater. But still 200A is usually to much for any normal charger to handle.
So anyway I seriesed all the caps together for a 15v bank. I charged them up with the battery intially then I used my Diehard 2/10/50A charger to top them off. I have had this charger for years and have monitored it very closely. It always has shut down right around 14.3/4v and floats from there until it drops below 12.7v I believe.
Well as you can see in the video its a pretty simple task and people shouldn't be too intimidated about the process. HOWEVER, once charged they do hold a LOT of energy that will do some damage. So once the are charged be VERY carefull with them.
