I have powerlab 8 with 24 V, 75 amp PS.

Quick question. Charging my larger batteries 5,000
6 cell in parallel. Should I be using
" High Power " or " Faster Charge ". Which
Would charge the fastest ? I've been using high power with no problems at all, just curious about what " faster charge " is. Thanks.

Brandon.

LiPo presets are grouped by charge current range. The respective preset is tuned for that current range. But you can use the high power preset down to 10ma. Its just that other presets are better tuned for low current charging. Here's the break down by preset.

Presets 1 and 2 (accurate and fast) are 2 to 10 amps. The High Power preset is for 10-40 amps and the under 2 amps is handled by the small balanced and unabalanced presets.

Here are the preset descriptions from the PowerLab 8 manual.

These presets are quite similar. The only difference being the default and max charge rates and default discharge rates.

LiPo Generic Faster Charge
Basic LiPo preset can be used for any LiPo battery. Fuel Table is optimized for generic LiPo batteries from C discharge ratings up to 20C. Selectable charge rates include 1C, 2C, 3C AUTO or 10mA to 10.0A manual. Optimization is for faster charging with termination settings of C/10 and max of 15 min timeout for C.V. mode. This preset does not require that every cell in the battery is charged to exactly 100%. If using high C rate discharge batteries (25C and higher), Fuel Gauge readout may not be accurate and AUTO charge rate may be higher or lower than expected. Default charge rate setting is 2C AUTO. Max Auto Amps parameter is default to 6A for this preset which means that unless you alter it, this preset will not exceed 6A max charge rate during AUTO charge. Other defaults: discharge rate setting is 2A, discharge voltage 3.3V/cell.

LiPo Generic High Power
High Power LiPo preset can be used for any LiPo battery, but optimized for medium to high capacity packs. Also good for balance charging multiple LiPo packs in parallel. Fuel Table is optimized for generic LiPo batteries from C discharge ratings up to 20C. Selectable charge rates include 1C, 2C, 3C AUTO or 10 mA to 40A manual. Optimization is for faster charging with termination settings of C/10 and max of 15 min time-out for C.V. mode. This preset does not require that every cell in the battery is charged to exactly 100%. If using high C rate discharge batteries (25C and higher), Fuel Gauge readout may not be accurate and AUTO charge rate may be higher or lower than expected. Default charge rate setting is 10A Manual. Unless you create a custom preset and generate a custom fuel table, we recommend using Manual charge rate settings when charging using High Power presets. Max Auto Amps parameter is default to 10A for this preset which means that unless you alter it, this preset will not exceed 10A max charge rate during AUTO charge. Other defaults: discharge rate setting is 4A, discharge voltage 3.3V/cell.

Have you installed the Charge Control Software (CCS)? If so, you can use the CCS to compare the values between the presets in question.

I've done this when I've modified a preset and wanted to compare it against the original factory preset.

One nice thing about the CCS is you can run it even if you don't have the USB interface. This is a great feature for those who would like to see what the CCS has to offer, but don't have a PowerLab charger.

The CCS can be downloaded here:

Thanks Ace, I ordered the connection cable from charger to computer but haven't connected it yet. Thanks for the info. I'll do that for sure.
