There are reports of different maximum voltages by users here as to the Megawatt's capability. Some say 15.3, others 15.5v.
I am space limited, and only wanted to deal with one AC charger and spent 127$ for a MEANWELL RSP-500-15, and it will put 41 amps into my depleted battery until battery voltage comes within 0.3v of the voltage I set it to before hooking it to the battery.
It will also do 16V which is more in line with Mex's prescribed eq regimen. Heck, it will do 19.23v if I crank it all the way up, but that capability is useless braggin rights territory only.
But it is a manual charger, which is fine with me. I'll take a manual charger capable of constant current rather than a one size fits all converter which perhaps comes close to the battery manufacturer recommendations.
It acts perfectly as a converter when set to a float voltage too. Powers any load under 41 amps and holds the battery at any desired voltage between 13.12 and 19.23
Through experimentation and testing and a hydrometer, I found my battery manufacturer's recommendations a bit conservative, and 15.7v could not do in two hours what 16v could do in a quarter of that time.
So now I don't screw around with anything less than 16v when I want an EQ on this particular 12v group31 battery.
When this battery fails the meanwell can be adjusted to any Lead acid battery which I buy to replace it and perhaps some other chemistries too, if they ever become an affordable option..
