5 tips for charging battery 18650 rechargeable

　　1. First make sure you are using the correct charger

　　Charge any polymer lithium battery at 1C, almost all drone lithium batteries can be charged at 1C and should be charged at that rate. 1C charging does take a little time, but this charging speed is the easiest for your lithium battery charger and won't cause overheating. This charging rate will give your battery the longest life possible, letting the balanced port do its job. For example, a 3400mAh battery charged at 1C would set the charger to a charge rate of Amperes.

　　2. Don’t let your battery drop below the minimum voltage

　　This is a flight issue, not a charging issue, but it needs to be addressed. While flying, try not to let the battery drain until the speed control starts to shut down unless you replace it. Then you have more time, more power until you land the drone. This avoids drone frying and you can control the minimum speed cutoff, set above the minimum voltage of the battery pack to have some extra time to set up for landing.

　　3. Unless the manufacturer's battery permits, accidents will occur

　　Charging the battery to above 1C, if the battery is using a higher charge rate, can save a lot of time when needed. Try not to charge these batteries at a higher rating if you don't need to. But other than that, I always use slower rates at home because it extends battery life.

　　4. Please do not leave the room while your battery is on the charger.

　　This is a mistake almost everyone makes and the number one safety concern when charging. This prevents any minor incident from becoming a major incident without leaving the room. Fires can happen at any time while charging while you are not in the room. You need to be there to monitor your battery while it's charging. If you must leave the room, stop the charger and disconnect the battery from the charging cable. Then when you get back to the room it recharges again.

　　5. If your battery has not been used for more than a week

　　Then please recharge your batteries, this will keep them balanced and stable. Storing charge prevents individual cells from becoming unstable and out of balance. I almost always charge my batteries and give them a full charge the night before.
