LiFePo4 batteries can replace SLA (lead acid) batteries with many benefits. The LiFePO4 battery uses a lithium-ion-derived chemistry and shares many of its advantages and disadvantages with other lithium ion battery chemistries. The key advantage for LiFePO4 when compared with LiCoO2 is higher current or peak-power rating.

While LiFePO4 cells have lower voltage and energy density than LiCoO2 Li-ion cells, this disadvantage is offset over time by the slower rate of capacity loss (aka greater calendar-life) of LiFePO4 when compared with other lithium-ion battery chemistries (such as LiCoO2 cobalt or LiMn2O4 manganese spinel based lithium-ion polymer batteries or lithium-ion batteries).

As LifePo4 batteries can handle deep charge/discharge cycles a 20Ah battery will have the same lifetime and capacity of 40 pounds SLA battery. Every LFP battery has a protection circuit ( BMS ) that handles the following functions :

1) Overcharge protection 2) Over-discharge protection 3) Short circuit protection 4) Over-current protection 5) Over-temperature protection Balanced protection 6) Balanced protection

Every Audioroot eSMART battery (li-ion and LiFePO4) embeds a micro controler which handles and records the main parameters of the battery such as : identification, type of elements, cycle count, build date, serial numbers and many other parameters. The micro controller monitors the battery's status and behaviour (power consumption, temperature, voltage, etc...) and can directly communicate these informations to our smart power distributors. Our eSMART LiFePO4 batteries are directly compatible with the following power distributors for plug and play operations :

eSMART BG-DU - Power distributor / universal fuel gauge eSMART BG-DU-REG - Regulated power distributor / universal fuel gauge eSMART K-ART - Dual battery location sound cart power distributor

This battery can be recharged with our eLC-PO4 low cost travel charger.

Poor quality — squeaker lasts 2 minutes
Color: Blue Squeak Toy, Size: Medium
These balls used to be great quality and long lasting. Something changed about a year ago and now the quality is considerably less to include the squeaker becoming inoperable within 2 mins of play. Not sure if the raw materials or the manufacturing process changed, however the decline in quality is obvious. I do not recommend this product to anyone who has a dog that is larger than 10-15 lbs.

STROBE: Favorite Ball, durable, decent battery life
Color: Glow in the Dark Strobe Toy, Size: Medium
*Update since Outward Hound redesign: The new version doesn't seem to light up as consistently on every bounce and seems to light up in a more seizure inducing way (I'm sorry I couldn't think of a better description). The light also seems to die much faster with the new version. The inner light and batter actually popped out its encasement in one ball after about 2 months of use, only by my Golden who doesn't chew particularly forcefully on it. I did notice right away and check regularly for damage, just putting that out there as a warning. It is still by far my dog's favorite ball. Original: This is my Golden Retriever's absolute favorite ball! Particularly the strobe light up ball but she's happy with any Planet Dog ball to the point that she looks at me for the "good ball" to fetch with if i try to have her play with a ball from a different company. Pros: by far my dog's favorite ball - good bounce, and good squish factor yet durable -larger size: safe for large dogs -lights up to see at night -decent battery life -rain does not affect battery Cons: -battery is not replaceable/ rechargeable (though I'm not sure it's an option without seriously altering the design) -regular glow (once battery is dead) is not great -only lights up on a bounce and shortly after that - If your dog bites down particularly forcefully it can displace the battery which typically kills it; if submerged in water (my dog tends to place it in her water bowl when she takes a break while fetching), it is reduces battery life, both make me worry about safety The ball always out lasts the lifespan of the battery for the light, I'd say we average about 1 month per ball while the light works with about 1 hour of use almost everyday. The ball does hold up to some of my dog's friends that are super chewers including one that is a Cane Corso. I don't let them sit and work at chewing it but they definitely squeeze it in their mouths with a good bit of force. My girl is happy to play with the ball even once the battery dies but I prefer to have the light so I can find the ball when needed. The glow color does glow when placed under a flashlight for a few minutes first but I find it doesn't glow as well or as long as other company's glow toys. My dog has a tendency to drown it in her water bowl to keep it nearby or rinse off any dirt and that definitely shortens the battery life but using it in the rain doesn't seem to affect the battery life I think this being my dog's favorite has to do with the good bounce and squeeze factor this ball has. I like that it's slightly bigger than a tennis ball so I'm comfortable with large dogs playing with it. It fits in the "large" chuck it ball launcher. I actually discovered this specific ball when another dog had it and my dog kept taking it instead of her other light up ball that she had played with happily for months.

Great for my pitbull, worth the price! the warranty isn’t what it seems so check their site first.
Color: Orange Squeak Toy, Size: Medium
I’ve now purchased 3 and I don’t see myself ever stopping! My 55lb Staffie (pitbull) has absolutely obliterated every ball and toy (rope, rubber, stuffed) before this one in a matter of minutes. You take your eyes off it, and the next time you’d look back it would be in pieces. Kong Xtremes and other “indestructible” toys only lasted a week, tops. He also goes nuts for anything that squeaks, so keeping him happily entertained for a while was a challenge because the second he’d chomp down on a squeaker, it’d break. He’s now had this blue squeak ball for a MONTH and it STILL SQUEAKS!! He regularly falls asleep with it still in his mouth, or tucked under his chin. That’s how obsessed he is with this thing. I would 100% recommend this to anyone who needs a seriously durable toy for their super powerful chewer as that’s been my experience! This material is super bouncy and he can bite down (unlike some rubbers, Kong/West Paw) without puncturing it somehow. It’s perfect for fetch, and floats too. He’s never had a toy last this long, so this is a welcome break for my wallet despite being a more expensive toy. I was buying a few toys every week until we tried this one! Cons: The first two balls didn’t squeak after a few days, so maybe they’ve improved something since then. The warranty replacement process is more tedious than others like West Paw, and only replaces them ONCE. It’s also requires more force to squeak this given the nature of the material, but since it extends the life of the squeaker I’m totally fine with it.

This ball has lasted and still have it after many months or longer. My dog loves it.
Color: Pink Squeak Toy, Size: Medium
My Belgian Malinois can really chew through inferior play toys and balls, etc., and this is one of the few that has lasted a long time, and he really likes it. Another bonus is that it gets quite slippery with his saliva and the ball will bounce a little bit unevenly, so it can either slip out of his mouth or bounce in an unexpected direction that can fool him. He has such quick reactions that is hard to get a ball past him, but with this ball, I can score extra points on him when he can't block it. Otherwise I have no chance, and he beats me every time.

Please go back to the original ball design and squeaker!!
Color: Pink Squeak Toy, Size: Medium, Color: Pink Squeak Toy, Size: Medium
Review update: I am updating my review for a few reasons. 1) The ball I ordered below was the 3rd time I purchased it. I originally bought one years ago, Pre-Covid, for my old pitty. My now Corgi, Jett loved that ball so I got a 2nd one for times when we couldn’t find the original. Well, the ball was slightly larger, the squeaker stopped working, and Jett preferred the original. 2) The newest one doesn’t squeak at all and is also slightly larger than the original. The original fell down the sewer drain that is in our backyard, and we lost the 2nd ball, so we ordered the ball again. My husband ended up having to retrieve the original from the sewer drain because Jett would pace around the sewer looking for the original. I ended up returning the 3rd ball because Jett doesn’t want anything to do with it & it doesn’t squeak. The video I provided is Jett squeaking the original that is at least 5-6 years old. I highly recommend the company go back to the original design that has not only stood the test of time and heavy use but is also the preferred size and for some reason has a much better, more reliable squeaker. I bought 2 of these balls for my Corgi mix and another for my son’s girlfriend’s Golden Retriever. Both dogs love the ball. They love the squeak and the ball is very durable. The ball doesn’t easily squeak by hand but will when they bite down on the ball or when it bounces. Speaking of, it has a decent amount of bounce to it too. Our dog loves to jump in the air to catch it after it bounces off the ground. I highly recommend this ball for medium and large dogs.
