Will a CBA II load test an data log? Or do I need a new version?

What is the Ah of a single 8.2V module?

 

I don't have a CBA II but from my own research, it should data log if you connect it to PC.

If you just want to load test a module, all you need is 12v/55w light bulb. Sylvania Xtravision 9003 H4 would work perfectly, especially if you connect two light bulb together = 55w+60w (high beam + low beam) = 115w/8v = 14-16 Amps of current, which is enough to load test a module. The pack of 2 light bulbs at Walmart should be around 20$.

The initial voltage of a module is 7.2v, there is 6 NiMH cells inside of a module, each cell is 1.2v. The Ah of new module is 6.5Ah, after years of use, it can drop to anywhere from few hundreds to 4000-5000mAh. Hope this helps)

 

Thanks, I've been doing a 50 W load test and trying to record voltage drops every 5 minutes and recording 2 A charge voltages up to 14 V then separating back to the single battery and charging it to 8V at 1.5A. Very long process, and easy to miss the 6 V stop point.

 

So, you are trying to cycles all the modules to regain some capacity by charging and discharging?

 

Cleaned the nuts bus bars and battery connections with CLR and yes tiring to find any bad batteries and regain some capacity.
