Product parameters:

The attribute of the lithium battery protection board:

charging pressure range: 4.28 v + / - 0.05 v

discharge voltage range: 2.5 + / - 0.05 v

The maximum working current: 100 a (Pay attention to heat dissipation)

Working temperature: - 40 - + 50 ℃

Maximum instantaneous current: 100-120 - a

storage conditions: - 40 - + 80 ℃

Static electricity: less than 30 ua

useful life: more than 30000 hours

Resistance: less than 300 m Ω

short circuit protection, can protect, delay the recovery.

The equilibrium current: 65 ma

Charging voltage: 12.6 V, 13 V

charging current limit: 10 a

T point: 

add a normally closed temperature induction switch can expand the temperature protection, should remove the solder side 0 r resistance.

Note: 

more than 3 a current discharge products, battery discharge rate is more than 3 c.

Ratio calculation formula: 

1 c rate of the battery, 2000 capacity is equal to 2 ah * 1 = 2 a working current.

3 c ratio battery, 2000 capacity is equal to 2 ah * 3 = 6 a 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.

Note 1: 

in accordance with the diagram wiring 0 V, 3.7 V (B -) (B1) (B2), 11.1 V, 7.4 V (B +), C - negative, C + battery positive and negative P + P - output output is, don't deliberately short circuit!

Note 2: 

after connected line need to recharge, just can have output.

Note 3:

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).

With 10 MOS tube, the powerful aluminium heat dissipation, sustained current limit 100 a. apply inverter, xenon lamp, solar street lamps and other three series of lithium-ion battery pack.

Warm prompt:

the protective plate cannot be used for electric fish machine, hernia lamp this kind of product.
