48V 100Ah Lifepo4 Golf Cart Lithium Battery, 200A BMS Low-Temp Protection 48 Volt Battery Support up to 5kW Motor 6000+ Deep Cycle Perfect for Golf Carts RV, and Off Grid Applications

I have a 36v EZGO TXT 4 seater running on the 38.4v 100ah variety and 48v Cushman Hauler running on the 51.2v 100ah version. When I first hooked it up to my TXT cart there must have been a sudden high current spike which caused the BMS to cut the power. Capacitors in a controller that's been sitting unused can cause current spikes. Sitting on a steep incline will require a lot of amps to get moving. Sticky brakes or a stuck brake pedal will increase resistance and cause a spike in current. I was able to wake the battery up by hooking it up to a charger. I was very cautious and went easy on the accelerator initially, but now both batteries are hooked up and powering my golf carts. They seem to be well made. The batteries came with their own wired displays. The display that comes with the 48v/52.1v colorful version displays the battery voltage, battery percentage, and real time AMP draw while in operation, compared to the 36v/38.4v version which only gives voltage and estimated percentage remaining.

WARNING: THIS BATTERY DOES NOT HAVE LOW VOLTAGE DISCONNECT Make sure your equipment is programmed to keep the voltage up. Our battery tested with a capacity of 40AH, which is no good, and ran down to 3 volts, which means the low voltage disconnect isn't there. Don't buy.

The battery is advertised at 48v 100 ah. When received, I charged at a constant current, constant voltage, with a desktop power supply set to 58.4v and 5.0 amps until the BMS shut down the charge at 55.2v. I then discharged at a constant current of 2.75 amps DC (well within tolerance). The batterys BMS shutdown the discharge at 52.5v well before the max discharge of 40 v and only allowed discharge of 78 ah total. A second test was run yeilding almost exact result. The vendors replys were all met with exact answers and additional testing but all they claimed was that was acceptable due to line loss and inefficiency. 22 Ah losses are not negligible, and i did not utilize any dc to ac conversion or high discharge rates, nor did i have large line losses though 12 in of wire at 2.75 amps, and i feel their is something discrepant, or the battery was mis-represented in the ad. Beware no returns are accepted sobif you get a bad one you are out 600+ dollars without any recourse. UPDATE The seller eventually sent a return shipping lable to correct this issue. Prior to returning, i decided to cycle the battery fully a few more times, and low and behold, the bms began to function properly. I am now getting the advertised output, (actually better 106ah). Needless to say if it keeps functioning as advertised this is an excellent value.

Worth every penny. This battery exceeded my needs and worked great on a my golf cart. Strongly recommend.

51.2v 100Ah battery arrived yesterday. Measured voltage out of the box: 20v. Thank you for the bad product. Will be returning this 40lbs paperweight.

so far so good but have only been used 4 times .it has made the cart quicker and no loss of power from the first hole to the last hole .so long as it keep performing like this for most of its life span i will be happy . Only thing so far i,m not happy with is the meter didn't work . And not certification of/for warranty sent . i contacted the seller and was offered a $30 discount but i asked for a working meter replacement .His reply was the meter was a gift as a type of good will gesture not part of the sale but is clearly advertised in the heading as part of the package .

Great battery delivered promptly. Also came with a Battery Meter which was an unexpected bonus. Battery works well as required.
