Mega Watt only 15.34V?

Thanks

I don't think anyone here has a S-400-12 yet.

I believe RJXJ has one. I''ll try pm'ing him.

Thanks Niner! I'll measure today!

Thanks for all the advice. After following a charging plan can I safely say that SG is the best indicator that the batteries are completely charged? And is there a range or specific SG number that indicates full charge?

1.275 or slightly higher, for all cells, is a good number. The higher, of course, the better.

I put my Schumacher sc2500a into storage today.

It too will do mid 16's, even on the AGM setting, and it won't go there slowly either, but blow right past the mid 14's and pump 15+ amps into a single battery at 16.4v, which is quite abusive in my opinion.

I had to monitor that charger like a hawk, or come back and find ridiculous currents being pumped into the gurgling spitting battery. 1 time out of 5.

If we are just seeking maximum voltage as some sort of urinating contest, my MeanWell rsp-500-15 will do 19.23v at well over 30 amps.

A useless feature for battery charging, but for a urination contest, quite the battle ax.

But if you want 16.0 or 15.5, or 14.8 you're screwed, right? It's like cooking RJ take a 10 lb king salmon stick it in the oven at 1,500F for three minutes and it all adds up right? The beauty of power supplies is they are voltage adjustable.

You don't troll at 40 knots for a reason. Simply yanking on a knob on a charger don't cut it.

Back the Mega back down to 13 and let the DC booster above to do the higher voltage stuff.

charge factor:

"the factor by which the quantity of electricity on discharge has to be multiplied to determine the quantity of electricity on charge required for the battery to recover its original state of charge"
