What I (and a lot of people according to Google) have found, is the pedals have some inherent design flaws with the batteries.
I’m using firmware 3.3.
My pedals would read low and after looking at the ride files, the LR balance would tend towards 100/0. Observing the balance while on a ride, 100% RHS pedalling with my left foot unclipped would result ona 0W reading. 100% LHS would result in a 100% lhs reading. When the RHS pedal was being pickedup, say 20%, the signal would drop out and then be 100% LHS again.
Taping around my batteries did not fix the drop outs (suggested Google solution 1)
My solution wound up being put a small bit of foam under the twin battery prongs inside the pedal. Since then, the pedal readings have consistently been around 45-55 LHS/RHS balance. (suggested Google solution 2)
It’s a bit rough hardware mods are needed for a $1500 bit of equipment to make it work!
