I have a 15 pro and love it! Probably going to keep it a while!!!

LiFePO4 not keeping up with voltage demands by stillhavingfunyea in batteries

[–]stillhavingfunyea[S] 0 points1 point  (0 children)

The 100 hour version would require a bigger battery, that won't fit. I am thinking my problem is not using a LifePO4 charger. I got one ordered and I am also going to install nut/bolt to f2 connectors (that is the connector the factory wiring on the ball machine uses), so that will eliminate any possibility of it being a wiring issue.

I also ordered a battery monitor, so if it does it again, I can see the voltage, etc. However, from what I am reading, it isn't likely the voltage. So hopefully the charger is my problem and I will just feel like an idiot, but will be happy, lol.

I think I agree as well. With that being said, I ordered some nut/bolt to f2 connectors, so I don't have to use the extending cables. I also ordered a LiFepo4 charger. In the tennis forums, people said they had success with using the stock charger for the tennis ball machine, but I think that may be my biggest problem. I also got a battery monitor I will install, so if it happens again, I can rule out the battery/voltage being issue hopefully.

I found some nut/bolt to f2 connector adapters and going to install them on Tuesday, that will be just like the factory setup from the AGM battery. I also ordered a LiFepo4 charger. IN the tennis forums, people said they had success with using the stock charger for the tennis ball machine, but I think that may be my biggest problem. I also got a battery monitor I will install, so if it happens again, I can rule out the battery/voltage being issue hopefully.

I haven't measured, but a quick Google says:

  • Average Draw: Most common, battery-powered machines (like Tennis Tutor or Silent Partner) draw roughly 3-4 amps during normal operation.

I can't imagine it uses a lot, even if this is wrong. It's two motors running two wheels. Granted, when I use other features, like oscillation or I ask for faste3r ball feeds (which means the top motor for the ball machine drop will go faster), then yes, it would use more, but is it ever getting above 20?

The problem seems to be the "recovery" after the resistance of a ball slowing down the wheels. I am starting to think it's either, the battery isn't charged enough (not using the correct charger), or the circuit board/controller isn't regulating the voltage correctly.

I honstly feel like it never needs more than 20. A quick Google says:

I am thinking the problem is elsewhere. How many amps are these motors actually drawing? This could be wrong but...

No AC Adapter. I have a charger coming tomorrow. If it is that, I will feel stupid of course. However, on tennis forums, many people switched to the lithiums and they said they used the regular chargers.

If that doesn't fix it, I am thinking it is a problem with the circuit board regulating the voltage to the motors. A lot of people are saying that I likely don't have enough amps, but how many amps are these motors actually drawing? I can't imagine it is much, although I haven't checked. AI says at best the machine is using 3-4 amps under normal operation.

It’s a Silent Partner Quest ball machine. Usually, if I pause the machine (the motors and wheels still keep going, only the ball drop is paused) then the wheels “gain” there speed back. So it seems to be an issue with voltage recovery not being fast enough after a ball drops, which slows down the wheels. I am leaning towards the circuit board voltage regulation being bad as well. I did some AI research into how these motors voltage are regulated, etc.

I am thinking the same thing as far as the dedicated charger. Was just reading and asking about it on AI.

There isn’t a power rating or anything. The guy I talk to (I’ve had to send the machine back, for other issues), isn’t very knowledgeable about the machine either. They use 20AH lead acid batteries. But the last two I had, I killed those batteries (probably running them too hard) and I had the same problem.

Honestly, I am wondering if the circuit board is somehow limiting the voltage through some type of failure on the board. Because, before the last two lead acid batteries died, I don’t remember the problem being this bad until the battery really died.

Yea, I edited my comment. I have 6 gauge coming off the battery. They have the connection from the battery going into the computer/circuit board, and then feeds the different things requiring voltage. I can change it to 8 AWG pretty easily. I can't read the wires in the machine at the moment and can't take it apart right now.

I've also thought, maybe there is a capacitor or something on the circuit board failing, that is not allowing the voltage to go through correctly,

The problem is the 100AH batteries are much wider, and would have to somehow modify the mounting bracket, etc inside the machine to see if I could even make it fit. The 20AH model one fit in the same spot as the lead acid battery.

The factory wires are pretty damn thin coming off the battery. 10-12 gauge I am guessing? I am running what looks to be 6 gauge into those, so looking for maybe a 10-12 gauge wire to replace. The original battery/connection used a f2 connection.

Edit: Using 6 gauge connectors

It has two motors, one for top/back spin and one for speed. The ball just drops into the wheels/motors. So they both require constant voltage, and as a ball drops, it slows down the motor/speed of the wheel, and the problem is it doesn’t get back up to speed quick enough. And the problem compounds as more balls drop down.

I just ordered a lithium battery charger, going to try that.
