ECO-WORTHY 48V 50Ah Metal Case Lithium Battery,Built-in 50A BMS, 2~3C Peak Current for Strong Acceleration, Lightweight Lead-Acid Replacement, 4000+ Cycles for Lawn Mower, Golf Cart, Solar Off-Grid

Works great, size fit in the Ryobi mower and use some wood to clamp in place and strap down.

Last year I purchased this to replace the 4 x 75ah lead acid batteries on my Ryobi RM480e riding mower. While 50ah is substantially less than the oem batteries, it easilly doubled my mowers working range. Only issue is that it's very hard for the guage to determine the state of charge given LFP batteries flat voltage curve. Overall I am very impressed with this pack. I will update this review if I run into any issues but season 2 is going just fine.

My simplified absolutely easy LiFePO upgrade of my Ryobi RM480ex riding lawn mower using the $400 Eco Worthy 48 volt LiFePO purchased on Amazon. All the original battery brackets and lead-acid batteries were removed from the slide out battery tray and discarded, since the parts were no longer needed. Only the main positive negative cable with the gray Anderson connector is reused. The blue charging connector was disconnected as well as the black cube shaped charger lock out relay and the now unneeded black rectangular temperature sensor connected to the negative battery post. The original charge port is removed by taking off three Phillips screws off the back of the port. The connector for the black cubic charge lock out relay is cut off. The yellow and red wires are stripped and connected together. The rest of the charge port assembly is not reused. The Eco Worthy battery is placed on the slide out tray and its boundaries are marked. 3M double stick tape (I used the clear instead of the foam which will retain moisture.) is placed within the space on the tray where the battery will sit. The battery is then secure with the tape. I used an 8 foot long luggage strap in an X pattern to hold down the battery. Any similar luggage strap will suffice. I then cut out all the protrusions within the charge port cavity and drilled half inch holes in the three places with a step drill bit. Since only the top hole is needed to the small XT60 socket, I covered the two bottom ones with half inch hole plugs, I fabricated two cables with 15 amp fuse and holders to make the charge cables. The 3/8 inch ring connectors were attached to the end to be connected to the main battery. I used 1/4 inch insulated spade connectors to connect the other ends of the XT60 socket to the fused charged cables. THey will go through the 1/2 inch hole to connect to the charge cables, but will not allow the XT60 socket to fall through. The positions of the male female connectors were reverse between the two cables to allow only the positive cable to be connect to the positive position on the socket. The photos show how the charger is connected with an extension XT60 cable with male and female ends, Everything except a few electrical connectors can and was purchased on Amazon.com for about $500.

I bought a 2014 EZGO RXV with Trojan Lead Acid batteries that were end of life and converted it to Lithium Ion with these two 50 Amp Hour batteries. It Rocks! It works great, very zippy, and very easy to convert. Much better performance than Lead Acid as it is lighter with far more power and range. I fabricated a battery box with perforated Aluminum for better air flow and cooling after removing the Lead Acid batteries, cleaning and neutralizing the acid with baking soda and water, fastening it to the existing battery base. Using rubber spacers between the two batteries made it fit perfectly for using the same battery hold down straps and bolts. I added a nylon strap, probably overkill. I added a onboard lithium battery charger Force 15 Amp, and a Shunt battery meter for accurate display of the state of charge and current, fitting into the existing dashboard spot. I used a couple of buss bars to clean up the wiring - I really don’t like hooking up all the wires to the battery terminals. The golf cart works perfectly, very zippy and quick, easy to use and easy to recharge.

Bought this battery to replace lead acid batteries in an older Club Car DS 48 volt golf cart. Upon installing was impressed with how it improved quickness, speed and how long a charge would last compared to lead acid batteries. After about 6 months it started having issues. Wouldn't charge, was giving very odd voltage readings. Upon contacting Eco-Worthy customer service they were very quick to reply to me via phone/email and eventually replace the battery. They diagnosed something bad with the BMS system inside the battery. I certainly hope I don't have similar problems with replacement battery. As I stated above I was very impressed with the performance of the battery but even more impressed with how quickly customer service acted with getting me a replacement.

It's a little early, but with some adjustments, it works fine. For my class of Golf Cart it uses dynamic braking. As such, the motor is a brake, and a generator. It's a 1C charging unit so it can only handle 50amps. The excessive power normally goes to the battery, but if the battery is charged, it dumps into a resistor turning into heat. The resistor has a sensor for heat overload and will shut down the controller (which happened to me). After configuring the Navitas (EZGO) , it's fine so far. Lead can take nearly infinite current, but not lithium. The metal case made mounting easy. Picture rotated, but takes much more space than lead. Had to change mount to make shorter.

I waited over a year so this review is real world. Works great. Highly recommend

This battery fits the Ryobi RM300E mower with minor modifications. The mod entails loosening a few bolts, bending a small piece of metal, and cutting one small metal ear. Only a basic tool set is required, and videos of this modification are easy to find.

La batería funciono bien unas 6 semanas, después un mañana el voltaje bajó a 0.4v.... después de investigar el problema una de las celdas estaba en 0.4v y las otras seguian en 3.29v... lo que indica que este bms a veces no hace su trabajo correctamente... tuve que comprar un balanceador activo y ahora ya funciona bien
