BATTERY CHARGING USING THE B6 - Part 3

START CHARGER

Be sure you follow, exactly, the printed instructions included with the charger. B6 charger charge parameters I use are:  LIPO - 3.7 V - 1.2 A. Press and hold the "Start" button for 3 seconds to begin charging. 

The charger will check your settings (LIPO - 3.7 V - 1.2 A),  and read the voltage of the battery to be charged. The "battery" 5x pile on the cable will be "seen" by the charger as: 1 battery at 3.7 V (nominal).

Remember they are in parallel ( all + to +, and all - to -,  and done automatically by the cable wiring). This means the voltages don't add, just the mAh values. 

Effectively those 5X batteries are now seen by the charger as one (1) battery @ 3.7 V, but the charger doesn't know there are 5X are in parallel.

What it will do is charge them all at the same time until it reaches 4.2 volts. This will take longer as  compared to a single, 600 mAh battery. 

But since the charger is set to 1.2 A ( double the UDI charger rate), the actual time will be closer to 2.5 hours for 5X batteries. That's about twice a quick as a single battery charging at 600 mAh. The B6 charge current will be about 240 mils per battery.

If all is correct it will allow you to press "Start" again and begin the charge sequence. In will automatically shut off at 4.2v (standard 100% or full charge). You are doing a parallel charge of 5x batteries, the shutoff will occur automatically at 4.2 V.

Check the voltage of all the batteries after the charging. There may be 1 or 2 batteries charges to 4.18 or so. Close enough. After measuring and sorting out the fully charged 4.2 V batteries, charge singly (one at a time), the remaining, now slightly undercharged (below 4.1 V) batteries. 

When the charger is done, it will shut off automatically. Put them in finished pile. When all are done, put the finished batteries into your flight case or box or what ever else you use to transport you equipment in.

Any batteries left? Repeat until done. I use 3X B6 chargers. I do 5x batteries per charger. It takes 2+ hours to complete the charge cycle at 1.2 Amps. With 3X chargers I can do all 14 batteries in about 3 hours. 

That's a lot better than the UDI charger which would have taken 15 hours to do 15 batteries. Then I'm ready to fly again. Why 14 and not 15 batteries? I fried one battery using the charger that came with the UDI U818A :(

BAD CHARGER!

First couple of times the UDI charger worked correctly, Them, for no apparent reason, it charge the next battery to 4.5 volts before it shut off. 

Yes, the battery died. 

I also have other chargers. Cheap stuff  I got from eBay. About 1.5" square, 5 charge ports, and uses the USB port on my computer for power. Works ok. It too has overcharged batteries. Now I use the B6 for ALL final charging.
