Usage & Charging

!!!!! IMPORTANT!!!!! These are immensely powerful batteries, and extreme care should be taken using them. Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these batteries with proper LiFePO4 chargers and equipment. Lithium Iron Phosphate batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge. 

Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

• Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
• Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
• Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
• Do not short circuit your batteries! NEVER short circuit any batteries! Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
• Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
• Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
