2 specifications: many battery chargers are available on the market, but few of them are universal chargers that can be used for all battery types. Using our kit, batteries of different voltages and capacities can be charged both quickly and normally. In order to ensure that the battery is fully dis...
3 assembly hints 1. Assembly (skipping this can lead to troubles ! ) ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 make sure you have the right tools: • a good quality soldering iron (25-40w) with a small tip. • wipe it often on a ...
4 assembly hints 1.3 soldering hints : 1- mount the component against the pcb surface and carefully solder the leads 2- make sure the solder joints are cone-shaped and shiny 3- trim excess leads as close as possible to the solder joint remove them from the tape one at a time ! Axial components are t...

9 connection 24. Connection connect a battery to the accu + and - connection. One of the battery holders from our range can be used such as: • type bh9v for 1 9v cell. • type bh322b for 2 aa cells (penlight). • type bh341b for 4 aa cells. • type bh363b for 6 aa cells. • type bh383b for 8 aa cells. T...
10 • mount a shunt over the 14h position. • select the battery voltage to be connected using a shunt on the 1.2v to 9.6v connection. • select the charge current with a shunt between 15ma and 750ma. The charge current of a battery can be determined by dividing the battery capacity by 10 (then select ...
11 • mount a shunt over the 52 min position. • select the battery voltage to be connected using a shunt on the 1.2v to 9.6v connection. • select the charge current with a shunt between 15ma and 750ma. The charge current of a battery can be determined by dividing the battery capacity by 10 (then sele...
12 note: only use the quick charge facility in the event of an emergency, as this type of charging can reduce the battery lifetime. Never mix batteries of different capacities. Never select two voltages or current settings simultaneously. Fast charge (52 mins).
