Great for my Lobster Elite tennis ball machine
Style: 10 AH
This 10 Ah battery replaced a 9Ah sealed lead acid battery for my Lobsters Elite Liberty tennis ball machine. It easily ran long enough for me to hit balls for two hours — it might run four or five hours the way I use it, but I can’t play that long anyway. It weighs 2.3 lb, far undercutting the nearly six pound lead battery. I needed make no accommodation to fit this into the space left by the old battery. They were the same exact size. The F2 terminals fit exactly. I’m happy to have a power source with battery management hardware. The charger that came with the machine didn’t live up to its claim of preserving the lead battery. I used that charger to top up this battery after every session with no problems. Update of December 5,2022: still no issues. I highly recommend this battery for tennis ball machines. Update December 10, 2022: I replaced the 11.7# lead 18 ah battery in a Lobster Elite 1 machine with another of these. Even at 38# we can manage its weight, having lost 9.4#. ... show more

So far so good
Style: 10 AH
Have been using this for a small solar setup to charge my phone. I have it set up in my south facing window and is working pretty good. Float charge is around 13.6v with my 20 watt panel. Have only been able to get above 14v a few times. Using a renology wanderer for my charge controller. The BMS works well and cuts the voltage when it drops to low. Takes a bit of time to get the battery to charge again after the BMS cuts the voltage. ... show more

Nice durability and current sourcing
Style: 10 AH
I bought this pack to augment two identical packs I've been running (occasionally) for a couple years to power my 50W ham transceiver. Once properly charged, the first two cells carried my radio well through a 36 hour event. Adding the third just assures that my radio will stay powered and ready.

Long lasting
Style: 10 AH
This battery works better than the factory batter in the electric kids jeep. But it seems to go a little slower but it has more power up hills. Charges faster and last longer. The battery is so light I wonder how much actual batter is inside of the case.

Stay in power and keep practicing!
Style: 10 AH
Excellent power source. Have you a neighbor that resents your -silent- piano practice so much as to shut off your utility electric? Be prepared and to plug into this nifty battery. Music practice need suffer not any interruption!

Superior Performance
Style: 10 AH
These batteries were purchased for a gate opener and have definitely exceeded my expectations. The original batteries for the gate did not last long and I was constantly having to charge them, even with a solar powered charger hooked up. I’ve had these batteries hooked up for a month and they are still running strong. They are incredibly lightweight as well. Highly recommend. ... show more
