I've got 4 of the

Controller:
We have some led lights hooked up, a controller fan and a speedo all probably drawing less than 5amps at 12v.
The problem is that when the battery draws down to ~56%, but go kart starts to sputter/surge. Seems like a capacitor is filling up and discharging every second or so. I assume this is normal behavior for these SLA batteries and there's nothing I can do about it. But I'm hoping this is not normal behavior and I can either introduce a component or adjust a component to allow the battery to drain to closer to 10% before power is lost.
