    My power supply trips on high current spikes during quick motions. I've been reading that I can use a 12V SLA battery to help provide extra current during these spikes/smooth the voltage drops.

    I'm currently using a bridge rectifier setup as a diode to prevent the EMF from the motors shutting down the PSU.

    Would I want to write the battery after the diodes like this?

    Would I have to worry about over charging the battery in a circuit like this?
    Would a 12v 6Ah SLA battery be suitable for 2x 200W motors that can spike up to 40A each?
    The battery is rated as: "Discharge current max: 81A for 5 sec"
