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

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.

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

Faced with having to replace the lead-acid batteries on my Ryobi 480e a 3rd time, I decided to switch to a LiFePO4 battery system instead. To get better lifetime and to simplify future battery replacements, if ever needed (for example, this battery weighs a bit over 50 lbs, vs. the almost 200 lbs of the batteries it replaced; also, LiFePO4 batteries can handle way more charging cycles than the original SLA models). Although this new pack has less power capacity than the set it replaced, if it lives up to the longer-lifetime spec for LiFePO4 batteries I'll get way more work out of this replacement than the original, so I'm calling this an "upgrade". Note that I had to change the charger (found a good one on Amazon for $130) and battery monitor (found a good one on Amazon for $30) as part of this change, since LiFePO4 batteries output higher voltage than SLA batteries. The overall cost even with these changes was barely over 50% of what a full SLA battery replacement would cost, and the prices of LiFePO4 batteries continues to decline (unlike SLA batteries). So far I've run the mower through 3 charge/usage cycles since this upgrade and love it! It easily gets 1 full hour of mowing on a large lot with lots of steep inclines, with plenty of capacity left over. Note: I do have good electrical skills, but this was not a difficult install. Just be very careful when battery power terminals are exposed.

For a mobile application (600 W LDMOS amplifier), I needed a battery that was a manageable weight and with enough watt-hours to last for 12-hour competitive events. One of these gives me exactly the battery capacity that I need, and at about 55 lb, it's manageable. It works like any of my 13-V LFP batteries--charges predictably, same size terminals, etc. The case is well-made too. Pulling 20 A out of the battery results in less than a 1-V drop at full charge. The load delivers full power with no hesitation. The battery charges easily from a golf cart LFP battery charger in a few hours. It's hard to find a better value for this kind of capacity.

These have been incredible to me. The metal cases make me feel a little better about the lithium lifepo4 batteries and the BMS (battery management system) protects from over charging, under charging and over current. In my usage I can charge to 58v before it stops charging. And will shut off after reaching 40v as is explained in the user manual. I will be buying two more very soon as the idea of having solar without batteries is not optimal. Here in Sacramento California, our utility company charges 2.5x the off hour rate from 5 to 8pm. That's where the batteries allow you to run off of them and save the most amount of money.

Works great, it's just a lot larger than anticipated. Make sure to measure.

Fit in the Ryobi 480EX mower great. Replaced 100ah of lead acid batteries with more usable power even though it's 50 ah. The mower ride is less jarring with the lighter weight and it climbs hills better. When I first turned it on, the mower shut off, and I could not get it to work, so I hooked a 5 amp fused wire from the positive terminal to the old red ignition wire in the ignition, and it works perfectly now.
