Underground Power 40AH LiFePO4 Lithium Battery RGB 5000W

Congratulations on your purchase of our lithium battery. You have in your hand the cutting edge lithium battery. They need careful management to be safe and provide a long service life. Fundamentally, they have serious risks associated with them and these must be understood to avoid danger, loss of property, and personal injury. Lithium batteries are NOT to be treated like lead acid batteries. That seems to be stating the obvious but for the majority of the people reading this instruction sheet, it is a significant one. You are probably replacing a lead acid (flooded, maintenance free, or AGM) battery with this new lithium battery. To get the most out of your new battery, specific care and procedures are required. Read this sheet carefully so that you fully understand what your new lithium battery can and cannot do. LifePo4 Battery Info Warnings To reduce the risk of fire or personal injury including burns: -Do not over charge the battery (meaning exceed the maximum voltage OR amperage and remove the charger once the battery is at 100% SoC.) By its very nature it cannot be considered 100% safe. -Do not short circuit the terminals. Use with alternators requires that the charging voltage be limited to 14.8V or less. 14.4v~14.6v is preferred. -Do not charge this battery if the terminal voltage is below 10.0V. Call Underground Power (1-309-533-5518) for assistance before proceeding. -Avoid high temperature. Never operate the battery in environments above 140oF or if the battery itself exceeds 140oF at any point. -Have a plan in place to respond to possible fire. (use ABC or BC extinguisher) -Disconnect the battery in total before welding anywhere on the vehicle. -Do not submerge in water. This battery is not waterproof. -Do not crush, puncture, or dispose of in fire or water. -Do not attempt to open, disassemble, or service the battery pack. -For battery disposal, most automotive parts stores or battery stores will accept old/used/damaged lithium batteries. Warranty Underground Power warrants that this product will be free from defects in materials and workmanship under normal use and service, subject to the express terms, remedies, exclusions, conditions, limitations, and disclaimers set forth below. Warranty Term and Remedies. For LifePo4 batteries (such as models 40Ah, 60Ah, 80Ah, and 100Ah in their 12v, 24v, and 36v formats), the limited warranty provided hereunder shall extend for one (1) years from the date of the product’s purchase. Should any covered defect in materials or workmanship be discovered during the limited warranty period, Underground Power will repair or replace the product free of charge minus shipping fees. The following damage is specifically excluded: Over discharge below 10V open circuit voltage or jumping your or someone else’s vehicle with a dead battery (under 11volts). Overcharge above 14.8V. Capacity is not guaranteed (ie. if the battery still accepts energy and discharges energy, it is considered “good”) Internal resistance is not guaranteed. (ie. if the battery was at 4milliΩ new and now is 6, 8, 10 or greater milliΩ internal resistance, it is considered “good”) Water damage and resulting internal corrosion. Physical damage such as case cracks from drops, impacts, or crushing it with a battery mount. This limited warranty shall not apply to damage to or failure of a product that results from: Any negligence other than by Underground Power; Accident (including, but not limited to, damage during shipment and natural disasters) Other circumstances beyond Underground Power’s control (including, but not limited to, normal capacity loss or increased resistance due to product aging) Improper installation, operation (including, but not limited to, abnormal or non-consumer use or use in an environment outside the recommended temperature range), maintenance, or storage (including, but not limited to, storage in an overly discharged state) Any other damage directly or indirectly caused by the product’s owner, other third parties, or other products (including, but not limited to, misuse, abuse, overcharging, over-discharging, exceeding of the product’s limitations set forth in the product’s specification sheet or label, neglect, physical damages caused by accidents or crashes, alterations, or connection to poorly-grounded battery chargers). This limited warranty shall also not apply to defects or non-conformities due to the manufacturing process discovered after the expiration of the applicable warranty period. This warranty does not extend to any damage caused by affixing any parts or equipment not purchased from Underground Power to the product and no warranties, either express or implied, are made with respect to equipment or products not produced by Underground Power. If the product is relocated outside of the continental United States during the applicable warranty period, the product’s owner will be responsible for any additional charges (including, but not limited to, shipping and other related charges and expenses) incurred during the warranty process as a result of such relocation. Charging Typically the battery will ship at less than 100% State of Charge (SoC.) It is recommended to charge your new battery as soon as you receive it. Lithium batteries are by their very nature voltage sensitive. Further, the lithium battery is the most vulnerable to damage while charging. It is important that the charging process of the battery be fully understood and carefully controlled. DO NOT use a charger on a “desulfation mode”. Remove the battery charger once the battery is full meaning 100% State of Charge. Unlike lead acid batteries, over charging lithium batteries DOES NOT help them nor cause them to store more power. Instead it harms them and should be strictly avoided. Lithium cells are in a state of stress when at 100% SoC and beyond. Continuous charging must be avoided. If the system is not full in 8 hours, call Underground Power. (1-309-533-5518) Lithium batteries do not have a “memory effect” therefore they do not have to be empty to benefit from re-charging. Simply recharge them when convenient and avoid overcharging. In general, float charging or battery maintaining should be avoided. Be extremely careful when making connections. Remember there is no low voltage disconnect, reverse polarity, or short circuit protection on the main terminals of this battery. Further, the power output of a lithium battery is four times that of typical lead acid batteries. Short circuits will flow huge amounts of current instantly with the ability to melt metal. Do not expose to temperatures above 60oC (140oF). Avoid mounting this battery in the engine compartment due to extreme heat. Elevated temperatures accelerate the aging process of most battery types and lithium batteries are especially sensitive to high temperatures. Conversely, cold temperatures can adversely affect the performance and charging of the lithium batteries. DO NOT charge under 7oC (20oF). In general, the lithium battery will outperform the lead acid battery it is replacing. If it does not, chances are you have a battery that is too small for the job. Stop now, take it out and return it for the correctly sized model. In general, pulling the battery’s terminal voltage below 10V for even the shortest amount of time is asking for a premature failure. This must be avoided. Lithium batteries have a relatively flat discharge curve when compared to a lead acid battery. The good news is that the average terminal voltage throughout discharge will be 12.8V for a 12V lithium battery. Unfortunately, this can make judging the state of charge difficult when the battery is near empty. Typically, Lifepo4 will rest around 13.3. Lithium ion batteries at a low state of charge will still show a relatively high voltage. It is important to get to know the limits of your battery because over discharge (discharge below 11.0V) must be strictly avoided.
