Built-in Battery Management system (BMS).4000 cycles to 100% depth of discharge! 100-amp continuous discharge current, 50-amp maximum charging current, -20C° to +60C° operating temperature range, 65% less weight than a comparable lead acid battery (22.85 lbs total weight), LIFePO4 technology provides a more stable and safer alternative compared to lead acid batteries.Wirelessly connect to Android and Apple devices by downloading the App from the App Store (instructions provided). See photos in the photo gallery for more information. Monitor and configure all battery information using your cell phone or tablet.Additionally, WindyNation’s BattaMax lithium battery is incredibly lightweight compared to similar deep-cycle lead acid batteries (22.85 lbs vs. BattaMax lithium batteries are designed specifically for deep-cycle performance for applications where the battery will be completely discharged and recharged thousands of times (the battery can handle 4000 cycles of 100% depth of discharge). The maintenance-free design is ideal for the following applications: aerial work platforms, floor cleaning, golf carts, inverters, material handling, oil, gas, recreation (RVs, offshore marine power, etc.), remote telecom, and renewable energy. Welding Battery Cable with Lugs and Heat ShrinkīattaMax Series LithiumLIFePO4 Batteries by WindyNation are true deep-cycle lithium batteries, specifically designed for providing off-grid power.And the defective battery needs to be returned to our US warehouse, and will be checked and tested by our technical team. ②If the problem can’t be solved, we’ll send new battery replacement to the defective battery. ①We’ll assist to analyze customer’s problem within 24 hours, and help solve problem, restore battery usage, and introduce the optimal use method And our five-year battery warranty includes the following privileges when used correctly in accordance with the manual instructions: And to fully charge the battery, the DC charging voltage should be between 14.2V~14.6V, and charging current less than 100A (for 12V 100Ah battery).ģ.We provide five-year warranty for all our batteries. And we recommend battery charger that support lithium battery charging. We don't provide a charger adapter with the battery. Because the golf cart generates a high current when starting, going uphill, or accelerating, the BMS board is activated for protection over time, the BMS will be damaged, resulting in the degradation or even destruction of the battery system performance.Ģ. Generally, we do not recommend using our battery for any application that need to be started. If you have any further questions, please see the product link below:ġ.Our battery is the storage battery instead of the start-up battery. Would you mind considering our self-heating battery models if you need to charge the battery at a freezing temperature? It has been released for battery charging at low temperatures and allows for battery discharge/charge at -20☌. Dendrites of lithium continue to grow with the cycle of lithium-ion batteries, eventually penetrating the diaphragm and causing positive and negative short circuits. Low-temperature charging of batteries may result in the formation of lithium dendrites in the negative electrode. However, charging the battery at freezing temperatures is not recommended for the following reasons: We’re really sorry for the confusion and the misunderstanding. If they need to charge the battery, they will take it inside the home (where the temperature above 0C). Many customers live in cold area, they are happy to use our battery, since it can be discharged very well, and their load can work under low temperature. After careful research, our team has decided to block this function. At the beginning, we had set up the low temperature cut-off function for our battery, but later many customers responded that they needed to be able to discharge it under 32F/0C. The BMS in our battery has low temperature cut-off protection function, but if we set this function on our battery, the battery can neither be charged nor discharged under 32F/0C. Even if charging in low temperature environment, it will not damage the battery. And we’ve used auto motive grade battery cells which have superior quality. Operating Temperature: Charge: 0☌-50☌ Discharge: -20☌-60☌.Ĭurrently our battery can be charged at low temperature, but it is charged with a very small charging current. It is like most kinds of the battery in the market now: Our battery can be used well below 0C (can be normally discharged), but we don’t suggest charging the battery below 0C.
