powerlab 6 "really" !

[Kap'n Krunch]

anyone know why my power lab 6 is overcharging the 6th cell on every single pack i own ?

I'm certainly not a PL expert. Hopefully Greg will chime in. But are you running the latest firmware? Balance wiring type (JST-XH vs FMA-style) is set correctly?

How far is that cell overcharging, for curiosity? Are we talking 4.201V, or 4.5V?

As RO says, which wiring mode are you using and which balance board are you using? Are you charging in parallel or as singles? How are you detecting the cell voltages? Cell checkers are notoriously inaccurate, especially on the last cell in the pack.

Report more details and we'll get this sorted out.

firmware 1.10 using xh/eh wiring with progressive rc balance board
charging 4 to 6 packs with accurate charging at home. I use high power charging at the field

yes over charging to 4.5

Is the charger reporting cell 6 as 4.5V, or is that another device showing 4.5V?

Is this a "normal" parallel board, or one of their new fully-fused modular boards?

"normal" parallel board, and a battery checker showing 6th cell as 4.5 will cross reference with another battery checker asap thanks

Does the charger show cell 6 as 4.20V, or 4.5V, when you're charging? It certainly *shouldn't* allow the cell to read anything higher than 4.20V while charging, but it seems worth asking.

If you have a multimeter, you could also simply check the voltage across the 2 balance pins for cell 6. Just be careful not to let the meter probes touch and short that cell

ok I forgot that i could view the individual cell voltage with the power lab according to it everything is spot on
