TP10 and TP210 balancer different reading then cellpro 4s

[528hemi]

After a completed charge on the cellpro 4s all cells report 4.2 volts balanced...
On the TP1010 connected to the TP210 balancer at 100 percent full charge the cells report about 4.18 per cell?

Is the TP1010/210 out of calibration? The total voltage from the charger on the TP1010 says 12.6 volts total but the balancer say slightly less?

Are other s seeing the same thing on the 210 balancer?

Thanks for the help

Only you can tell us for sure which is out but you'd need to use a DMM that itself is in good cal and has very good accuracy

However, the difference between 4.18V and 4.20V is 0.48% which is pretty darn good.

The Cellpro manual says the cal accuracy is +/- 6mV (0.006V) but only a +/- 10mV measurement accuracy. Worst case is 0.016V inaccuracy - about what you are seeing.

Both could be out a bit, and this little bit I wouldn't worry about.

Thanks Dave!

Out of the box the TP charger is set to 95% charge. Change it to 100% and you should be good to go.
