Manufacturers how to assembly production of lithium batteries? - Shenzhen battery
nowadays us every minute of everyday life is not a lack of electricity, electricity every minute are for all of us in intimate service. Most of us with all the electricity are all derived from the power plant electrical, home appliances with large and medium-sized life doesn't always move, therefore, with a power socket, all of them are safe to use anytime and anywhere, every time we must use often carry electronic security products, not every minute with a power socket, and therefore must be safe use battery to supply electric power transmission and distribution for all of us, for lithium battery if you have a lot of questions? Below we look at the manufacturer how to assembly production of lithium batteries. 7 all also can see us. 4 v2200mah underwater vacuum cleaner 18650 lithium battery specific parameters.

lithium electricity protection, overcharge protection, discharge protection, over-current protection discharge, discharge short circuit protection, etc.
the preparing work before lithium battery assembly
a, 7 in well packaged. Before 4 v lithium-ion battery pack, you must first according to lithium battery enterprise product size and shape of the motor load capacity and calculation done, then the required capacity is calculated according to the enterprise product must be packaged lithium battery capacity, then according to the formula to the choose and buy lithium battery.
2, lithium batteries will do a good job of neat put first, and then the safe use of materials for each series of lithium batteries will do a good job. In stabilizing after each series of lithium battery, the best safe use, like barley paper insulation partition each series of lithium battery, put the lithium battery after skin damage and cause a short circuit conditions.
3, solid lithium battery container must also be prepared to arrange the lithium battery pack pack prevention, a move will cause change. string will do a good job segregation of materials, and in order to better effect, every two lithium batteries with silicone rubber glue adhesion together.
7。 4 v18650 lithium battery assembly detailed basic tutorial
the first step, select the appropriate batteries, batteries type, voltage, resistance must be matched, packaged before please keep the balance of batteries. Cutting electrode and opening.
the second step, on the well hole distance, the system insulation board.
the third step, ready for screws, safe use flange nut, please avoid nut off, ready for screw connection is good, can keep the lithium battery pack pack.
the fourth step, cohesion and welding line, connecting line voltage acquisition ( Line of balance) Don't external lithium battery protection board, avoid accidentally burn out lithium battery protection board.
step 5, insulation resistance silicone solid again, this kind of silica gel in the long run will cure.
step 6, put the lithium battery pack protection board, if the balance of batteries, forget to do before it is lithium battery assembly before the last chance, can do balance through the line of balance.
step 7, and to stabilize the whole battery pack with insulation board, wrapped with nylon tape, nylon tape more endurance.
step 8, and then the whole batteries packaging format, please try to secure good batteries and lithium battery protection board, all of us fall batteries measured 1 m height still to ensure the normal work.
step 9, with a solid insulation board to the lithium battery pack, wrapped with nylon tape, nylon tape more endurance.
step 10, the integral form of encapsulation batteries again, please try to secure good batteries and lithium battery pack protection board, all of us fall batteries measured 1 m height still to ensure the normal work.
then, output input adopts silica gel line. Because of the whole is lithium iron batteries, also is the total weight acid half of body cell.
then, basic tutorial has been completed, we do the inspection after the completion of measurement, lithium-ion batteries can meet the requirements of all of us.
However, custom lithium ion battery isn't the only producer in domestic, and many people feel that Shenzhen Chuangneng Ruiyuan Electronics CO.,LTD.'s service leaves much to be desired in terms of functionality and design.
Knowing these basics of is every essential. But if you don't know how to choose the proper for your specific need, let Shenzhen Chuangneng Ruiyuan Electronics CO.,LTD. experts be your guide. Enquire us at Ruiyuan Electronics.
Regularly improving custom lithium ion battery in accordance with customer feedback is a great way to show your brand listens and cares.
Shenzhen Chuangneng Ruiyuan Electronics CO.,LTD. will give you a suitable price for purchasing custom lithium ion battery.
