3S 40A Li-ion Lithium Battery Charger Lipo Cell Module PCB BMS
Protection Board For Drill Motor 12.6V with Balance
Product Description:
Description:
- 3S 12.6V 40A lithium battery protection board (comes with recovery
function-AUTO Recovery)
- Scope: Nominal voltage of 3.7V lithium battery (including
18650,26650, polymer lithium battery)
- Product Size: 41 * 55 * 3.4mm (Enhanced Version), 41 * 60 * 3.4mm
(Balanced version)
- Product weight: 8.8g (enhanced version), 9.8g (balanced version)
- Charging voltage: 12.6V - 13.6V
- Continuous discharge current (upper limit): 40A (if the cooling
environment is not good, please reduce the load current )
- Continuous charge current (upper limit): 20A
Enhanced version:Suitable for electric drill with starting current
below 80A and power below 130W .(without balanced function)
Balanced version: Suitable for electric drill with starting current
below 80A and power below 170W .(with balanced charging function)
- Note 1: To successful starting the drill requires three 15C-20C
power batteries, or six 10C-15C power batteries (ordinary 18650
battery can not start the drill!!).
- Note 2: When you wiring 0V, 4.2V, 8.4V, 12.6V, please do it
strictly according to the wiring diagram.Do not deliberately make
it short circuit.
- Note 3: When the battery is charging,the "430" resistance heating
is normal,it means the balance circuit is working.If the "430"
resistance is also heating without charging,please check if the
wrong wire is connected.
- Note 4: Do not use a mix of good battery and poor battery,please
make sure each battery is the same in capacity and internal
resistance. 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! 3 sets of
battery capacity / resistance closer to the better! (2 good battery
+1 Poor battery use effect = 3 poor battery use effect).
