3S 15A Three series 11.1V electronics circuit board to 12V 12.6V PCB BMS circuit board assemblies

3S 15A Three series 11.1V electronics circuit board to 12V 12.6V PCB BMS circuit board assemblies

The custom printed circuit board cannot be used for lithium iron phosphate batteries, hernia lights, hand drill battery packs, electric fish machine battery packs,bicycle battery pack, children's car battery, 550 or more power motor, 1W fish-eye LED light, please pay attention to customers who purchase the above combination!

electronics circuit board application:
Massager battery back-up power, LED backup power, 12V electronic products, solar street lamps battery pack,monitoring standby power and other products.

• Note: more than 3A current discharge products, battery discharge rate is more than 3C.
• Ratio calculation formula: 1C rate of the battery, 2000 capacity is equal to 2AH * 1 = 2A maximum working current.
• 3C ratio battery, 2000 capacity is equal to 2AH * 3 = 6A maximum working current.
• In use battery heats is ratio is not applicable to, this kind of situation can't use for a long time, the battery will soon be damaged.

• In accordance with the diagram wiring 0 V, 3.7 V (B-) (B1)(B2), 11.1 V, 7.4 V (B +), don't deliberately short circuit!

• After connected line need to recharge, just can have output.

• 3 series battery, please make sure that each set of battery voltage, if not, please separate with each set of batteries in series.Discharge test, the battery voltage drops quickly is a bad battery.

• Note: don't put the good cells and in bad!Three groups of battery capacity/internal resistance as close as possible!(2 + 1 good battery,the use effect of poor battery = the use effect of three bad battery ).
