Thanks Niner, good to know I can retask my 10 turn trim pot on a Mega watt if that is what I wind up with.
Mena, confirmation can't hurt but don't go through any (more) hassle for me.
So Niner, you want me to acquire the 400 watt Megawatt?..... How bout draining that T-1275 to 75 amps hours from full, Set the MW to 15.0v, hook it to the battery and let that megawatt loose on it, max it out. See if it does the 33 amps for 30 minutes then 30 amps for 3 minutes then 33 amps again for 30 minutes like the claims on the homepage. If it does, I'll click place order on confirmation.
If it drops to 20 amps in a warm climate, No thanks.
I smoked the cheapowatt charging the screwy 31, not the AGM. The AGM was charged the night before and I moved the trim pot about 12 times in 70 minutes to keep the amps above 32amps and under 36.2 amps, and then kept lowering it slightly afterward to keep battery voltage from going past 14.7v.
On the screwy 31, I set it to 14.7v, hooked it to the battery, and blue smoked it at the 17 minute mark.
That kind of makes me wonder about the condition of your Screwy 31? I have no idea how this Mega Watt will handle batteries in poor, worn out sulphated condition, or on their last death bed, shorting out a cell?
