I have 2 rechargable battery packs,1) 6V, 3200mAh2) 7.2V, 3600mAhQ1) Can I attach both of them in parallel (by first making sure they measure same volts at that time) because I was wondering, what would happen when I'll charge the combined battery !? as one of the packs can reach 7.2V, while the other 6V only. [if not, any alternate solutions?]Q2) Would I get a total power of 3200+3600 6800mAh ?Thanks.
Don't do this, Each of the batteries will have different resistances, also when the 6V battery is fully charged you need to keep going for the 7.2v battery, which means that you will be heating and boiling the electrolyte in the 2nd battery.
NO, they are different voltages, what will happen is that the second will discharge into the first, until either one is discharged or the other is overcharged and damaged. If they were of equal voltage, you could put them in parallel, and perhaps you could charge in parallel, although that depends on the charger. It may be risky. Yes, in parallel, the mA-hours do add. No, no alternate solution, it just doesn't work. .
q1, No, not a good idea. q2, No, the 6V pack will add very little. But if you added a cell to the 6V pack, or removed a cell from the 7.2 V
Any good rechargable AAs (like the 2500mAh Energizers I have) will last just as long as the Nyko Wiimote packs. But the AAs have several advantages: 1) About the same price for a charger and 4 AAs as for a Nyko charger and 2 packs. But Spare AAs are cheaper and easier to get. 2) AAs and chargers for them can be used for other devices. 3) AAs can be charged outside the Wiimote, meaning when they run low, you just swap them out. 4) You can buy a 15-minute charger for the AAs. No so for the Wiimote battery packs. 5) Major battery manufacturers are less likely to go bankrupt or stop supporting their solution for the Wiimote.
