GRAPHENE 12 Volt 100AH Lithium Ferro Phosphate Inverter Battery, Solar Compatible, Back Up More Than 180AH Lead Acid Battery, Long Life Up to 20 Years, Works with Any Normal Inverter, 5 Years Warranty

The Graphene 100Ah Lithium ferro phosphate battery is an excellent package and it can provide better back up than a 150Ah lead acid battery. It is very compact in size weighing just under 10 kg and can be coupled with the regular home inverter system and the installation process is very simple and the supplier is also very much customer friendly.The battery itself comes with a Bluetooth device which can easily be paired with your mobile after downloading and installing a BMS App from Google Play store (Supplier will guide you for the installation). This App will display all relevant information of the battery pack which include battery voltage, charging/discharging currents, left out capacity of the battery, individual cell voltages, cell temperatures, Number of charging/discharging cycles etc. etc.One point, which need improvement is the output terminal (wires) provided with the battery. The battery pack is provided with two flexible wires each of about 8- or 10-inches length (fully insulated up to the end) and two connection clips which need to be crimped and fitted after removing the insulation from the tips. But this must be done with extreme care as there is every chance of getting short circuited. Again, the connection clip provided with the battery is not compatible with the universal inverter connection clips available with the inverters and a separate nut/bolt need to be used for coupling with the inverter inputs. Further, these joints need to be insulated with insulation tape which give a shabby look. More over, think of a case where your inverter/battery pack need some repair/servicing. While disconnecting, it is really going to be cumbersome process as you have to remove the old sticky insulation tape, loosen the nut/bolt, insulate the disconnected end and repeat the same for the 2nd terminal etc. etc. So, my suggestion is that instead of providing the two flexible wires, provide two fixed terminals on the battery unit itself (just like the Lead acid batteries) so that the inverter terminals can be directly connected/disconnected quite easily.Let us hope that the manufacturer will note the above point(s) and implement the suggested modification(s) soon.

Since the day I purchased this bettery, it is so easy to manage and very much durable and high power backup. The great thing about this product from my personal experience is the after sale support. This product has excellent customer support system. I am planning to buy one more unit and add it in the current capacity and I am recommending everyone to replace their traditional old Acid batteries with this one. It is also very small and lightweight which makes it easily manageable.

Quality is good, little expensive than what local assembler is offering.

After three months of usage, the GRAPHENE 12V 100AH Lithium Ferro Phosphate Inverter Battery has demonstrated significant performance degradation, falling substantially below expected technical standards. The battery's charge retention, voltage stability, and overall power output have been critically compromised, suggesting potential manufacturing or quality control issues.The battery's performance substantially deviates from standard LiFePO4 battery expectations, raising serious concerns about its reliability and technical integrity. These unexpected performance limitations require immediate technical investigation and potential product replacement.Urgent manufacturer intervention is recommended to address these critical performance challenges and ensure product quality meets advertised specifications.

Excellent product. It's really too much better than lead battery. Value for money.

Very nice battery,too much portable BMSMobile connectivity useful for user.Customer Care Service satisfactory.

My graphene is not performing well at all it has just increased my worry since it was installed and is now not functioning what should I do please contact me as soon as you can

Graphene lithium phosphate battery is a very good battery for every normal inverter it is capable to celebrate every inverter.It is working very good with my sukam brainy plus inverter.Backup time is great and more than lead acid battery.❤️
