Have you experienced the battery shutting down before it's fully charged, yet claiming it is 100%? On numerous occasions, my batteries will cut off alleging they're 100% full, but the voltage is only around 16.3 volts. It will be charging away, still pulling 5 amps, and cut off saying it's full. Then of course, it thinks it is full and cannot resume charging again.

I've just discovered this problem. I have a new battery with less than 3 cycles on it. I just finished a charge cycle and the battery shut off. My multimeter is showing 16.22 volts which is 4.05v per cell.

Something is not right

I'm waiting on my 2nd battery to finish charging so I can measure it.

Plot thickens. Put the battery in the solo and powered it up. Solo app reports 16.6 volts and 98% charged. My 2 multimeters both measure 16.2 volts.

Battery #2 - purchased at the same time (only 3 cycles). Fully charged 16.3 volts on my multimeter. In the solo powered up the 3dr solo app reports 16.6 volts and 99% charged.

Note: I charge my batteries with the stock charger.

@PdxSteve, just to clarify is the cc/cv charger you mentioned an actual charger (like we use for other lipo's) or a power supply only?

 

[PdxSteve]

It's only a power converter and needs an external DC power supply. I'm using a 120/240 AC to 12 Volt/50 Amp DC power supply to feed 6 of them to charge 6 batteries. They boost the 12V to 16.8V and also limit the current to 6A which is the max the solo battery can take.

Anybody try one of the B6 chargers yet?
