ECO-WORTHY 48V 50Ah Metal Case LiFePO4 Battery, Built-in BMS, Replacement of Lead-Acid Battery, Allows Discharging at -4℉ and Charging at 32℉, Stackable, for Solar Off-Grid, Golf Cart, Lawn Mower, RV

I purchased this single 48V Lithium battery to replace the 4, 12V lead acid batteries that were in my Ryobi 1st Gen riding mower. While these have half the amp-hours of the original batteries, I still get over 2 hours of mowing time with this single battery. The best part is that this 1 battery weighs less than 2 of the previous batteries, so the overall weight is cut in half. Full charge time of this battery is about 4 hours using the "DC HOUSE 48V 18A Lithium Battery Charger, 900W Fast Charger" which I also purchased on Amazon. The original charger that came with the Ryobi can not be used with lithium batteries. Overall I am very happy with this battery.

I am seriously impressed with this battery after replacing all 4 of my lead acid batteries in my Ryobi electric mower with this one 50Ah battery. It has better life than when I got the mower brand new, which used to struggle to finish my 1 acre yard on a slope, whereas this battery finishes the job with plenty of life left. As long as it keeps up this kind of performance for a couple years, I will never not buy an Eco-Worthy battery (if it dies before then, I'll update this review).

By far these are the best bargains for stacked batteries. Purchased when they have been offered at a discount. Easy to install. Solid quality build, shipping was excellent, no problem, package was extra boxed so the internal box was not scuffed up, it's nearly 60lb.Charge to 58.4vdc or 100% no issues. BMS prevents overcharge. Fast and efficient shipping.

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.
