3S 40A 12.6 Balance
Application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650.26650, polymer lithium battery).
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;Suitable for the drills with starting current below 80A, power 135W below.
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 the load of the motor brush is used, try to connect to the non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
Note 4: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.
For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try 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).

ESP32 is a complete,small form factor(SFF)802.11 b/g/n/e/i(2.4GHz)WLAN plus BT4.2combo solution optimized for low-power,mobile consumer electronics,wearable andInternet of Things(IOT) devices.ESP32 integrates all WLAN and BT functionalityin a single package to support a low cost,layout-friendly implementation whileallowing flexibility for platform specific customization.
   ESP32 is a highly integrated solution withless than 10 external components.
   ESp32 integrates the transmit /receive RFfunctionality including the antenna swiches,RF balun,power amplifier,low noisereceive amplifier,filters,power management,and advanced calibratiom ciacuitriesthat allow the solution to dynamically adjust itself to adapt to externalcircuit implefections.
   The entire solution reduces Printed CircuitBoard (PCB) area,time-to-market,and bill-of-material(BOM)costs while addingcapablities and processing power.the mass production of ESP32 does not requireexpensive and specialized Wi-Fi test equipment.
   ESP32's uitra low power consumption radioarchiteature and proprietary power save technologies extend batter life inreal-world applications,using the following features:
   Fine granularity clock-gating
   Multiple low-power modes,and
   Dynamic voltage scaling
   For instance,in a low-power IoT sensor hubapplication scenario,ESP32 is woken up periodically and only when a specifiedcondition is detected;low duty cycle is used to minimize the amount of energythat the chip expends.The output power of the power amplifier can also beadjusted,so that an optimal trade off between the communication range,data rateand power consumption is achieved.
