With the new battery I was getting 5 and a half hrs without any spin nor oscillation and with the standard speed of 60 mph , since I play with plenty spin and with two line or any of the pre-programmed drills , a little over 4 hrs was all I used to get .
Now after 2 years , playing time has dropped dramatically to about 90' , this is not enough for me , therefore I am buying a new one .
I can not buy a bigger size because it wouldn't fit inside the machine so I can only go for bigger capacity .
I was going to buy a silicone lead greensaver 24AH , but then I saw a lithium battery twice as expensive as the green saver , I started doing some research , and apparently , I say apparently because I am not an expert on batteries and I can get lost with the specifications , it can give you much more running time .
Does anyone have experience with Lithium Iron Phosphate batteries ???
Any input would be much appreciated
A friend of mine had a Tennis Tudor with a lead acid battery. He replaced the battery with two white plastic battery holder tubes that had 3 or 4 rechargeable D cells in each tube. I assume that they were Lithium batteries. They were very reasonable in cost.
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.
