Hi testers ,
Highest cell against lowest cell in the battery pack wil give the real delta.
Difference between MM and charger is normal , but should be as less as possible .
I compared the MM i use with theXL830Ll ;
- Xl830l - € 6,35 incl shipping on ebay ;
DC Voltage |
200mV/2V/20V/200V/600V +/- (0.5%)
|
Voltage DC |

So , according to the specs the xl830l should even be better than the Fluke 110 ( and a lot cheaper !! ) . à i am not going to discuss mm here ;-)
I have calibrated my charger with a little device i made , mainly consisting of a reference temp compensated voltage reference and a 0,1 % resistor voltagedevider .
The benefit of that is , it allows me to set every voltage needed so i can do a low voltage calibrations as well ( fe. 2 volt on all 6 ).
According to the info , what mostly counts is how much energy you can get IN the battery preferably with a safety marging towards the 4,23 V max limit.
A good easy and cheap way of testing a whole battery is the BVM-8S ( chinese cellog 8 knockoff ).
