Re: 108 100ah calb cells It is a divider board I built to spoof the bms ... I can use any size pack up to 384 volts with it since it makes the truck think all the batteries are

Re: ranger-ev Yes but I only use the Ranger around town, so the drag should not be so much on an issue? I will see if I can get a watt meter and check out my charger. Mike

Re: Additional Batteries in the Bed The ICS200 reports the time and charge in KWh, I don’t know how accurate that is, and I agree that 16KWh’s is only about half a charge. Could I get 60

Re: Additional Batteries in the Bed How are you measuring kWh? My BMS shows amp-hours so a little easier on the math. In theory if you have 100 Ah cells (3.2V nominal) then you have about 32 kWh
