Q:How to charge our batteries?
A:If you have purchased a peak charger,just stick to the directions.
If you have purchased a timed charger,you will have to be very systematic about charging and discharging your batteries,or else you will ruin them quickly.
Here's how to proceed:
Every time you customize the battery, charge it fully while monitoring time it requires. (New batteries will always be offered fully released.) Can you be sure once the battery is fully billed? By holding battery inside your hands and preventing the charge once the battery begins getting warm to touch.
Place a label around the new battery saying the number of minutes it requires to charge.
Never charge a partially billed battery. Always discharge it by running it inside your UAV before the UAV begins to get rid of its punch (more about this below under "How do you turn off and on?") Allow the battery awesome before re-charging.
Charge a completely released battery based on its label, or perhaps a couple of minutesless. When the battery isn't warm in the finish of charging, you are able to "peak" it by charging a little many monitoring the temperature together with your hands.
You now appreciate why peak battery chargers count the additional money.
Don't charge battery power when it's hot from getting used. Wait for this to awesome, utilizing a fan if you would like it to awesome faster.
Q:How to make the most use of lipo batteries?
A:Structure – Li-Po batteries, as the name suggests, uses a Lithium chemical base and is suspended in a polymer matrix (now you know from where the name‘Li-Po’came). The average cell voltage of a Li-Po battery is 3.7 volts, the operational voltage ranging between 3.3v and 4.2v.
Safety – Li-Po batteries are proven to be safe and user-friendly under normal operational circumstances but they are not known to take mishandlings really well. If you were to use Li-Po batteries for your UAV, be prepared to be a careful handler of these batteries.
Q:What is the charger rate of the batteries?
A:The charging rate of our LPD lipo packs can up to 5C+ without problem, but we usually recommend our customers to charge with 1-3C.
Q:What connectors are on the transmitter batteries?
A:For Transmitter/Receiver lipo packs, we usually can also use above listed charge balance connectors for you for charging.And always use FUTABA/JR or both for you for discharge as you need.
Q:How to ensure the quality?
A:LPD maintains a perfect quality assurance system by implementing most strict quality control and inspection procedures in every stage of the production process
Q:How to check the battey?
A:Plug your voltmeter or muli-meter towards the red-colored and black connections around the battery to obtain total current.
If you wish to check individual cells. You are able to plug as much as the whitened balance plug.
Q:How to storage the batteries?
A:Batteries store at a place with low-humidity and free from corrosive gas within the temperature ranged from -20℃to +40℃.
If storing a long time,batteries must be stored at about 3.8V/cell (approximately 50% charged)/ in the semi-electric status(about 3.8V).Do regularly charge & discharge them for maintenance(about 1-3 times every 3 months.
Q: How fast can I charge a pack?
A:Each Lithium Polymer battery pack has a different maximum charge rate. It is very important to never ever charge at a rating above the specified rate!
Q:What is battery cycling? Is it important?
A:Battery cycling is using some form of loading device (ideally a adjusted charger having a discharge function) to empty the present from the battery power until it approaches the cheapest safe current for that pack, then re-charging those look out onto its peak capacity again.
Frequently 3 complete cycles are carried out to assist 'condition' battery power, ensure that it's able to holding an entire charge, and also to maintainOrimprove the existence and toughness for battery pack. Cycling need not be achieved frequently.
Q:Battery should be removed after finished using it?
A: Yes, you are recommended to remove or detach the battery.
Q:What is Cell Balancing?
A:Lithium Polymer batteries usually come packaged as a pack of more than two individual battery cells. For example, UAV use 3-cell packs. Each of these battery cells has a nominal voltage of 3.7v; which means that each cell can operate when it maintains its charge between 3.0 to 4.2v. To go above or below or below this range can damage the cell and render it useless, or worse, become dangerously unstable and explode.
Q:What is C rating?
A:A lot of radio-control fliers quickly grasp the meaning of most of the battery-associated acronyms but one: the C rating. In fact, many experts have tripped over themselves trying to explain it. However, I've heard a graspable explanation of it from an old Chinese battery manufacturer/expert very recently. Which is: The "C Rating" is the number which you multiply to the capacity of the battery to get its discharge rate.
Q:Who are your OEM customers?
A:Due to we have made agreements with our customers to keep their information as the business secret. Just not for others to advertisement. Hope your kindly understanding about this! Thanks.
Q:Do your batteries come with PCB protective boards?
A:Regarding PCB protective boards, usually we use them for standard discharge current lipos for protection. For high discharge current lipo packs as listed in our prices list mainly for RC models, usually we do not put PCB in them, due to this is not good for the RC models during the process of flying.
As you know that the PCB has a limitation of current, so when you are doing some 3D aerobatic flights or some other motivations which need a high discharge current to support the RC model to finish their flights.
If this high discharge current was limited/cut-off by the PCB, then the RC models will be crash down during the flying process. So for high discharge current, we usually do not use PCB boards. And on other hand, the cost for such kind of PCB is also high. So please just feel free to use our lipos for your RC models. Expect your kind understanding.
Q: What news about shipment?
A:Pleased to inform you that the batteries are nearly finished well, and we will send them out to you tomorrow or next Monday, due to the EMS service couldn't transit the cargo during the weekend. Expect your kind understanding. Thanks.
Q:Price list with my cost and retail cost.
A:Considering our long-term business cooperation relationship, could you please kindly find our special prices list attached for your further reference. And for your retail cost of these lipo packs to end users, we suggest to sell these lipos based on 2-2.5 times of this special prices list for you according. Meanwhile, you can make some proper adjustment according to your local markets status. Thanks.
Q:Does your price include shipping?
A:Our quotation is based on FOB terms, which is not including shipping cost. Thanks.
Q:What connectors are on the transmitter batteries?
A:For Transmitter/Receiver lipo packs, we usually can also use above listed charge balance connectors for you for charging. And always use FUTABA/JR or both for you for discharge as you need.
Q:Are you also going to work with the new li-fe cell
A:Yes, we are also planning to work with the new lipo batteries. I will provide our lipo battery catelogs to you for your further reference when we get this prepared in the near days timely.
Q:What is the warranty of the batteries?
A:Our warranty policy is we will replace the defected lipo packs within 3 months free of charge and 6 month half under proper usages and storages excluding in a crash of our AGA lipos.
Q:How long will it take to ship sample order?
A:Usually we can delivery the goods out within around 10-15days as we have most of the cells in stock to meet our customer
Q:Does your Company produce these in house?
A:Yes, we produce these lipo batteries in our own houses. Just because we were mainly provide our lipo cells to some big and potential distributors in Europe and USA in the past years as OEM services. So we rarely promote our batteries with our own brand. But so far we are planning to and going all out to promote our own LPD brand lipo batteries. And we are also seeking for some potential customers to distribute our batteries. So it is no wonder that you haven't heard our brand in the lipo battery markets before.
Q:The life of lipo packs
A:For example, I have heard people say that the Lipo batteries have a Production and an Expiration Date! Meaning that if the Lipo is "Old"
Q;Danger and Warning and Caution in handing the battery?
