New for 2018 is varying battery capacity. We have 3Ah, 4Ah and 5Ah +packs. Bigger packs will take longer to charge from empty. The +capacity is on the cell label next to the yellow connector.
This is blue charger with 3 LEDs, and diagrammatic charging info on RH side. CHarges at up to 100W.
+This is the set of 3 (2 half-width) chargers made from old Makita chargers. They have a set of 4 LEDs. (The full-width one only has 1 LED in 2018). Charges at 40W.
+ +This is black all-purpose charger with blue LCD display. CHarges at up to 50W
+ +The Yellow Propeak chargers do the same job, and insturcuctions are +similar, but have no fan, no backlit display, and if pack is low +voltage will charge at C/10 (10% of normal) until voltage rises +sufficiently. Ensure that charge rate is set to 4000mA otherwise +charging will be very slow. Charges at up to 50W (5W in C/10 gnetle start).

For 2018 this was done for 7 of our +packs, and 3 automatic balance chargers built.Note that the drills have no battery-voltage monitoring at all, and the monitoring circuit is bypassed when conected to the drill (the charger
