We have dedicated battery charger up to 1000W. If none of these chargers meets your demands and you would like to choose a power supply as a charger, we advice to pick up one which over load protection (OLP) mode is constant current limiting. The models in this mode provide constant current even when the protection circuit is triggered. HLG series (A-type and with a little adjustment) is a very good range for charging batteries.
The second choice is fold-back current limiting or constant wattage model. In this model, when a battery is running low, the output current of the power supply will gently increase. The level of increase depends on battery’s capacity and degree of exhaustion.
Hiccup or shut down model are not recommended because it will stop to generate current when OLP happens.
