which tools for mesurement?

[pasteque]

hi , i will be interested to know which kind of tolls you use to test your battery and cells
i use to have a medusa research PA pro , that i enjoy , but medusa stops production unfortunately , so i'm looking for an equivalent........ and for single cells? is there any specific tool that i ignore?
thanks!

Check out CBA III from West Mountain Radio. People around here seem very positive. I'll be buying one a a week or so.

thanks a lot but the problem with CBA III is that , according to their data sheet , it is limited to 150 watts
in fact don't understand cause in some points they say 55v 30A and in another sentence they say 150watts and since i'm not an english speaking person perhaps i miss something
thanks for help

What it means is that it will do 55V or 30A but not at the same time. Max power is limited to 150W so for a single cell it will allow up to 30A. For a bigger pack it will be restricted to the max power handling and may only allow 5A for example. You can add external loads that can increase the power rating to 500W and add additional loads to have a total power handling up to 2000W.

ok , but for 2000w the cost...... :?
isn't there a cheapest solution to monitor discharge curve of lifepo packs up to 16S(or 24s? i can dream) and 1000/1500w? in fact the brother of power analyzer from medusa will be perfect , i have already an adjustable load

Il n'y a rien comme ca. J'ai chercher pour quelques chose comme ca, mais il n'existe pas. Excuse, il existe, mais c'est trop cher. Et le grand probleme avec le CBA, il teste seulment un pile par fois. Je veux tester peut-etre 10 par fois, mais ca n'est pas possible avec les outil maintenant.
