18650 polimer lítium akkumulátor 3S 4S 5S univerzális védőlemez 20A rövid ideig tart 40A
18650 polymer lithium battery 3S 4S 5S universal protection plate lasts 20A short time 40A
Model: Ternary lithium battery 3 series 4 series 5 collusion protection board
This protection board uses mature protection circuit, special IC, imported large current ultra-low internal resistance MOS (single MOS internal resistance is as low as 3 milliohms), with perfect and stable charging and discharging of various protection functions.
Small size and large current can be used for power tools, model aircraft and other occasions with large current.
This protection board is a power type high current lithium battery protection board, suitable for large current equipment, such as power tools, motors, electric drills and other equipment.
Notes:
Note 1: B- and C- wires should be connected with thick wire, and ensure that the welding pad is correctly welded with the positive and negative terminals of the corresponding equipment.
Caution 2: Before installing the protection board, ensure that the batteries are well matched (the voltage difference of each battery is no more than 0.05V, the internal resistance difference is no more than 5m ω, and the capacity difference is less than 30mAh). The protection board is used to protect each battery string. If the voltage of one battery string is too high or too low, it will be protected. The better the consistency of the battery, the longer the power of the battery, the better the performance of the protection board.
Note 3: Connect a single battery to a required number of battery strings, and then connect the battery strings in series.
Note 4: When three batteries are connected in series, ensure that the voltage of each battery is the same. If the voltage of each battery is different, charge each battery separately and use it in series. In the discharge test, the group of batteries whose voltage drops quickly is the poor battery.
 
Note 5: do not mix the good battery and poor battery use together, the capacity of the battery pack, internal resistance as close as possible.
Note 6: This guard plate cannot be used for lithium iron phosphate batteries.
 
Note 7: Do not use the lithium battery protection plate in series.
FAQ:
1. Can MY battery use this protective board?
A: There are two issues to consider whether you can use this protection board: how many strings of your battery, you should buy the corresponding number of strings of protection board. Second, what is your battery made of? We have lithium iron phosphate and polymer two parameters of the protective plate, if your battery is lithium iron phosphate single nominal 3.2V need to choose lithium iron phosphate 3.2V in the classification, if polymer (ternary, cobalt acid, lithium manganese oxide battery) single battery nominal 3.6V (or 3.7V) please choose polymer 3.7V classification.
2. How can I tell what my battery is made of?
Answer: you can take a look at your battery nominal voltage, lithium iron phosphate battery is generally standard 3.2V, other batteries are generally standard 3.6V or 3.7V, you can also directly ask the seller of the battery is what material of the battery, many buyers said my battery is 18650 or 26650 soft package, this is the appearance, not the material oh! We cannot determine your battery protection parameters according to this.
3. How many protective boards should I choose?
A: How many amps to choose depends on your load power, our protection board is the same port output, output 1 series of current is 16A, 2 series of current is 25A.
4. My battery is 20AH, can I use this protection board?
Answer: your battery capacity size and use the current size of this board actually have no direct relationship, the capacity is not the battery is large, mainly look at the continuous current, that is to say your load is bigger, you choose the protection board continuous current is bigger, with the battery capacity has no direct relationship.
5. How to set the charger voltage?
 
Answer: lithium battery must be charged with a special charger for lithium battery, do not use lead-acid battery charger, lead-acid charging may have high voltage breakdown of the protection plate MOS tube, resulting in protection plate overcharge is not protected. Charger voltage setting: use your battery string number *4.2V which is the charging voltage of non-iron lithium battery, the charging voltage of iron lithium battery string number *3.60V which is the charging voltage of iron lithium battery, the charging current standard is 0.2 times of the capacity.
