Hi Fred, Maybe you can trick your charger by adding a second resistor of the same value parallel to the original for current measurement, so the current measurement shows half the actual current and then configure your charger to charge and discharge at half the max value so that now the 100Ah limit is actually 200Ah It remains a hack, and you will need to carefully document the halved current indication to avoid overloading your charger...

I've searched the world (wide web) over, but haven't been able to pin down the correct specifics to accomplish my goal. I'm hoping someone here has that valuable commodity known as experience and can better advise and/or direct me. I have 180AH LiFePO4 cells that I want to test over an extended period of time. I have an R/C class charger unit, almost perfect for my requirements, but it tops out at 100AH on the charge sequence. It also "bottoms out" at the same value on the discharge sequence. It's exactly what I need, a device to cycle the batteries, measuring the energy in both directions, but for the 100AH limit. Does anyone have suggestions regarding a more suitable device? Even in the R/C world, the limits are so low, but also not something easily found in searches. Suggestions for search terms would be useful too! thanksfred -------------- next part -------------- An HTML attachment was scrubbed...
