Purchasing a power supply that can take in any voltage between 120 VAC and 240 VAC and put out 10 to 30 VDC will keep your options open.
Likewise, purchasing a charger that can take in 12 or 24 VDC will also keep your options open.
Some, to save money on the power supply opt for salvaged/surplus Dell or HP server UPS power supplies which can be put in series to achieve 24 VDC output....
but that will depend on their design configuration as parallel can do damage as well..... or you can go this route:

Additional information:
You are approaching the threshold where you will need to seriously consider 24 VDC power supply and charger. But also you might want to seriously consider using 220 VAC versus 120 VAC residential outlet.
The reason for that is that 120 VAC circuits are restricted to 15Amp max breaker sizing and those will trip too frequently at 120 VAC with the type of battery load you are trying to charge.
Safety warning: Do not upgrade you house distribution panel for 120 VAC circuits above 15Amp breaker sizes. Those breakers are sized to protect your house wiring.
Any higher and you could burn down your house.
I ran a subpanel to my garage from a 2 pole 30 amp breaker in my house main breaker panel c/w 220 VAC rated wiring. That allows me to quickly switch up to 220 VAC if/when I need it whether for PHEV "pluggable hybrid electric vehicle" or big capacity MR Battery charging.
Hi All
Would like to know what power supply and charger you guys would recommend for charging large batteries ....9000mah and up?
Something with more then 5A max . My old charger just does not seem to be up to the task. Any make and model that does a quick job
of getting full charge
Thanks William
