I burrowed the machine. Although I did not do long hitting secessions I found the performance to be very satisfactory for running the machine. They are much lighter than a lead acid battery. I guess that you could analyze running time using amp-hours.
The machine manufacturers should research using them instead of lead acid.
I posted the details in this forum I believe but did not find searching so far.
Thanks for the input .
What I would like is to hear from someone who bought a brand new tennis machine , because they all come with lead acid or gel at the most , and then decided to switch to lithium .
I would like to hear from someone like this , because that person would know exactly the parameters of both batts , and that can really help .
