Description:

4S 12.8V 40A   Iron lithium battery   protection board 

 

Scope: Nominal voltage of 3.2V, 3.6V  Iron lithium battery  (including 18650,26650, polymer lithium battery)

 

Product Size: 44 * 55 * 3.4mm (Standard Version), 45 * 60 * 3.4mm (Balanced version)

 

Product weight: 9.2g (standard / enhanced version), 10.2g (balanced version)

 

Charging voltage: 14.4V - 16V

 

Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)

 

Continuous charge current (upper limit): 20A

 

 

Package include:

2*Iron lithium battery Charger Protection Board

 

 

Standard version: suitable for starting current below 80A, power 200W below the drill.(Not balanced function)

 

Balanced version: suitable for starting current below 80A, power 200W below the drill.(with balance)

 

Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!).

 

Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.

 

 

Note 3: When charging the battery, the "360" resistance heating is normal, indicating that the equalization circuit is working; if the "360" resistance is also heating in the non-charging state, please check whether the wrong line is connected.

 

 

For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 4 sets of battery capacity / resistance closer to the better! (3 good battery +1 Poor battery use effect = 4 poor battery use effect).
