Q & A of lithium-ion batteries


  • Q & A of lithium-ion batteries of lithium-ion batteries


A ask:  How to check Cell Volume Energy Density?
Answer:  If Lithium-ion cell is a type of INR18650-3.6V-2200mAh,  so the calculate formula is 3.6 x 2.2÷(0.9 x 0.9 x 3.14 x 6.5÷1000)= 480Wh.L

B ask:  How to Inspections Material of Lithium-ion Battery pack?
Answer:  * Li-ion cells testing passed by battery's separator.
               * PCB testing passed by the Electronic testing machine system.
               * Check plastics & stickers by Quality Check Department.

C ask:  How to Inspections the Battery pack?
Answer:  All battery pack must be repeatedly charged and discharged by Aging machine.

D ask:  How to Inspections for Sample?
Answer: Random Inspections passed by the testing machine (testing items: voltage and capacity and data information).

E ask: How to the Battery Current storage?
Answer:  Usually the batteries current keeping on 70%~75% storage.


F ask:  How long will this last at 100% charge?
Answer:  This depends on the RC model work current. Normally it can work about 15 minutes on 450 Quad for 2200mAh 11.1V 25C lipo battery pack.

 

G ask:  What is the charge time of the battery?

Answer:  The max charge rate of battery is 5C, but for maximum lifespan and performance, it is better to charge it with 0.5C-1C (balance mode of charger).

 

H ask:  Can I wire 2 of these in series and double the power?

Answer:  Yes they can be wired in series to double voltage or can be wired in parallel to double amp.

 

I ask:  Can I use a higher mAh battery than what is recommended?

Answer:  Yes, you can use the highest mAh battery that will fit in your rc model. The larger you go, the more weight you will add and the more run time you will get.

 

J ask:  Can I have some samples for testing quality?

Answer:  Yes, you can buy some samples of any our products for testing quality and market.

 

K ask:  What is delivery time if we place an order?

Answer:   It depends order quantities. Usually, we can deliver goods within 3 -5 working days for small orders, for more QTY. order, let's confirm when you place offical order.

 

L ask:  Do you accept OEM or ODM?

Answer:  We support OEM & ODM service: Please don’t hesitate to tell us your ideas.
