What separates the Megawatt from old fashioned transformer manual battery chargers is it's adjustable voltage All the difference in the world for safety and accuracy The missing control is a timer...

the 'Grape Solar 40' PWM controller is rated for 40amps
and voltage is completely adj via your android phone using bluetooth, via the app downloaded from them
it has FLA, AGM, and lithium settings
and you can change them to your hearts content
settings will be retained in memory,
change battery, turn on app, connect to controller switch battery types
there is NO amperage control, only voltage settings,
disconnect settings, reconnect settings, float settings, etc. etc.
and timer setting for bulk mode, i think i set mine at 4hrs
to keep bulk voltage for 4hrs, if the sun is available, this way the higher voltage 14.6v could top up the batteries, instead of dropping out to soon
was $49 when i bought mine, i think they are now $79
available on Amazon and Home depot
