6PCS 3S 40A Li-Ion Lithium Battery Charger for Drill Motor 12.6V

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 x 55 x 3.4mm (Enhanced Version) 41 x 60 x 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 below 130W .(without balanced function) Balanced version: Suitable for electric drill with starting current below 80A and below 170W .(with balanced charging function) Note 1: To successful starting the drill requires three 15C-20C batteries or six 10C-15C batteries (ordinary can not the drill!!). Note 2: When you wiring 0V 4.2V 8.4V 12.6V please do it strictly according to the wiring .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 a mix of good battery and poor battery please make each battery is the 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 ! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery effect = 3 poor battery effect). Colour: green Material: plastic Package Contents: 6 * Lithium Battery Charger Module Only the above package content other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
