Anyway, that's the problem. I just ran it for an hour to charge the 20ah lithium pack, the whole heat sink gets *very warm* under load, I'm guessing it's the older inefficient diodes. But still, it does work properly. I'll put it back in the tractor later and start testing the Lithium pack next weekend.
Yikes! You're using the GE charger to charge a Li-Ion battery pack?That's a dangerous route you're taking. Even with proper protection in the pack. There is not proper protection in the charger for this use, the voltage levels will be different, there's a good chance the current levels will mismatch etc...
Li batteries are much (much, much) more sensitive to charge conditions than lead-acids. Even the LiFe varieties.
