I wouldn't chance that charger, I've had a few like that and haven't lasted long/been safe. Something like this http://www.bmsbattery.com/alloy-shell/23-alloy-shell-180w-lifepo4li-ionlead-acid-battery-ebike-charger.html would be better, plus you can customise the setup when ordering to ensure the right voltage/current/plug type.
