Better for what?

For the main battery for my go kart

the 33ah are going to last longer than the 10ah putting out 36v, how long? I couldnt tell ya

Amp=watt/volt
Amp=1000/36
Amp=28
33/28=1.2 hours or 1 hr 10mins approximately off a full charge.
I would get an extra 12v battery if you can afford it, as people usually overclock motors by 12v.
Also check out rapid online for cheap batteries.

the lipos are going to be waaaay lighter but you would need 3 of those packs in parallel to get close to the same amp hours (read: Runtime) that you would get from the SLA batteries.

They are also well expensive!!!
Reminds me of my brothers torch battery,12v 15ah about £150!!! It's lithium though and weighs about 1/5 of sla.
