Universal Charger iMax B6 can charge the lithium, NiMH and lead-acid batteries. At the same time you can charge up to six lithium batteries. There is a possibility of balancing, but balanced cables in the bundle. I finally bought the wire and take care of the balanced charging.


To charge the batteries connected in series, it turns out that if the physical properties batteries differ (and they always differ at least slightly), part of the battery nedozaryazhaetsya and part recharges. To resolve this problem, use balanced charging, in which the additional wire is connected to each battery.

At iMax B6 has five connectors balancing - at 2, 3, 4, 5 and 6 batteries. On Aliexpress sold balancing sets of wires under all connectors and I bought a set of $1.22.


It turned out that it is enough just one connector - six-pin. Contact all the balancing connectors are connected at the iMax: all connectors on the right minus, then touch the plus of the first battery, then the second and so on. Five jacks for connecting ready made assemblies battery with balanced connectors.

Good soldered holders on six batteries (for $ 1.23 one battery, for $ 1.95 two) and soldered to them six-pin balancing connector.


With this display can be charged 1, 2, 3, 4, 5 and 6 batteries. If the battery is less than six, they are put. from minus contact. Power contacts are connected charging as follows: always negative to negative of the first battery, positive - to positive last (depending on the number of batteries it can be a different contact Holders).

On iMax BAL selected mode (not CHG).


If, during the press charging Inc button will display the voltage of each battery.


For balanced charging it is important that the batteries were discharged the same, otherwise the charging may take a very long time. If the charging current dropped to 0.1 A, the voltage of one of the battery reached 4.2 V, and the voltage is much lower than the others, better then charged and stop charging the batteries separately. This can be much faster.

P.S. In any case, I add the wiring diagram, taken from the Internet.
