A long while back I showed a fence charger I had designed. Wookie mentioned the float charge circuit was flawed.
Here is what that section looked like.
Here is the same schematic revamped.
The idea is the battery is kept fully charged, but is used to provide a large rush of current if needed. The actual discharge is quite low (30ms pulse every second). I got the idea from working on gap discharge units, where large amounts of currents are needed for extremely short duration.
I basically picked R13 out of the air (100ma max) and would like some feedback on it and the rest of the concept. Thanks.
