51.2V 100Ah

  • I purchased these home backup batteries for the off-grid power project. Attention to detail was very good for a complete the box ready for-action product. It was simple to assemble and install the batteries into the rack and hook them up to have battery backup at the ready. Secondly, I like the protective shell inside the battery and the wide handle, which is rare but outstanding in its category on the market. The LCD screen and buttons used to operate the BMS system are also very user-friendly in design, making it very simple for me to keep track of the battery's status.
  • Shipping was not as fast as I expected, but after receiving the goods, I was impressed by the appearance of the whole battery. After using many homogenized black casing batteries on the market, EFG's white casing and built-in white cell cover are undoubtedly refreshing. Connecting it to my solar power system also worked smoothly; it was a good value purchase.
  • It took a lot of time from placing the order to shipping the battery to Joburg, but even after a long journey, the battery inside the package is still 100% brand new. I think this is due to the company's emphasis on the packaging. I haven't had time to install the battery into my solar system yet, as the mounting frames I purchased elsewhere are still on the way in the shipping. Still, after a brief review of the product's exterior, the cells, and the instruction manual that came with it, I think shopping is worth the money this time.
  • Batteries are well packed arrived. They are loaded and ready to use. The quality is outstanding. Delivery time was the current circumstances appropriate. Best!
  • So I connected the battery as a storage device for the solar system. After a period of operation, I can only report positive things. Even a discharge current of 100 A is no problem. Hope it stays that way in terms of quality and reliability.
  • This is a terrific battery for the cost and it appears to be very well made compared to most of the other brands I have seen. Not only am I very satisfied with the battery, but also with the company itself and their customer service which is top notch and second to none that I have dealt with in the past. I was very impressed with their responsiveness and help throughout the process.
  • The battery is successfully connected to my inverter. The BMS had written the communication protocol with the inverter, and the installation did not take more than 5 minutes. Great!
  • Excellent battery and company. Ships fast, well-packed battery with no damage. The battery is good quality and has proper attachment bolts, which will help me mount it on the wall easily. I have not had time to install them yet. I will add another review when they are in use. so far so good.
  • I have used this battery several times while living off-grid on the land. With this battery, I can recharge using my roof solar panels, which seems to be a great way to charge it. With this battery, once it has a full charge, it lasted me almost 4-5 days, depending on how much use it got within that time. It came with everything needed for me to connect something to it to power my device up and connect it to my solar panels. Within the 2-3 weeks, this outlasted my old battery by days. This battery is still going strong and does pack a powerful charge.
  • I've only had this battery for a couple of days, but so far, it works great. I bought this one specifically for the heaters as I am using it for my garage in the far north. I'm currently running a fridge and a TV with this battery, and it has plenty of power storage for those needs. I'm debating on buying another to double the capacity. But maybe if it is on sale at a discount, I'll snag a 2nd one of these.
  • I’m using this batteries now. Best built in BMS I’ve seen. I especially like that I can add more batteries, when the budget allows, without having the existing units affect the new such as the case with lead acid battery. I recommend this product and seller.
  • I finally got the product. It was a perfect shopping experience
