So it begins...... Battery spot welder

Ok, towing Fionagirl in her chariot with new BAK battery, our top speed increased from 19 to 23 mph.

23mph was just barely achievable solo, with these motors, when that battery was new with all urethane wheels.
I'm running 8x3" pneumatics at only 8psi up front now, which have far more drag.

Unloaded max speed on the bench is 26mph.

There is a very noticeable torque increase when towing Fiona on the crushed shell trail.

The remote has a 4 bar battery level indicator on it. It used to fall to one bar on our way to the water on the CST. It now stays at 4 bars.

The extra torque and top speed is because of much less voltage sag under load, because.of quality Tabless cells.
No idea how hot this battery will get, nor the amount of increased range, yet.

I've a tracking number for new 90mm hub motors, shipping from nearby.
Same motors as I had before I dunked them in the bay and dislocated my shoulder.

They were a lot quieter, and smoother, with longer freeroll, and had top unloaded speed of 30mph and I once hit that solo, wind and terrain assisted. It's too fast.

I have extra 90mm urethane sleeves for them, and can get more.

Some 105mm sleeves are available too, but at the cost of lost torque and braking force.
