MegaPower Infinity 960SR / Robbe Power Peak Infinity 3

with LCB-12S balancer.

What it does not make clear in the balancer manual is that you have to combine the red wire from the first balancer cable harness to the first wire of the second harness, if you use it with a pack of more than 6 cells. Spare harnesses are available from Robbe - Item 1-4021, Voltage sensor cable 7-P.

Below are a couple of graphs of the 960SR near the end of charging a 10 Cell pack of A123 Lithium cells. The iniial charge current is 4 Amps. The 960SR reduces the current when the pack voltage gets to an average of 3.7 Volts per cell, but you would want to charge at a much lower inital current (around 0.5 Amps) if the cells were badly out of balance.

Bought a PC connection lead from Robbe - item 1-8295, Interface Cable Infinity 2+3. Can be used with LogView, although V2 seems to be only available in German at the moment. I just used it to capture a log file and save into an Excel spreadsheet.

After the first charge, I left the balancer connected for 30 mins or so, continuing to balance. I then briefly disharged the pack and performed a second charge - graph 2, which resulted in the pack being well balanced.
