Re: 12V battery BCI Size?

Lead acid sucks as a storage battery, but it's hard to beat the safe, reliable, low maintenance, and dependable nature of a lead acid starter battery. Tesla uses a regular lead starter battery just like everyone else. To save weight and extend range, Boeing tried to use lithium as starter batteries ...

What is to be gained? What is the Benefit?

But why-- Because it weighs less? That is too little useless a benefit for the risk of failure. The price for this little UPS battery is the same as the full-sized lead acid in the miev. Plus it is way undersized for the current loads of a running car with headlights ON. The chemistry requires a dif...

Re: new program for monitoring charge readings

i think what is puzzling to everyone is why do the BMU and CMU voltages not match up exactly--there is about 0.100 volts difference between the two for the same cells. Which value is correct, and why is there an indicated difference in the readings? This is a problem that needs to be answered before...

Project to add temperature reading to odometer button

Maybe someone is interested to explore their car and help out? i got a PM from a fellow in EU that wants to redo the 93c66 eeprom in the speedometer to add the outside temperature to the push button options of the odometer gauge. It seems that the EU cars don't have that feature-- i don't know? This...

i would bet that your problems will go away when you replace the OEM aux battery. Put the money for the obdii tool toward a new battery. i hardly ever use my scantool, but i use that battery every day...

What is the age and condition of the 12V aux battery--is it the original OEM or has it been changed, etc.? We have a separate thread devoted to troubleshooting the OBC/DCDC Converter with lots of detailed information in post #2 about testing the 12V aux battery. i would have expected to hear that th...

Re: Turtle at Half Charge?!?!?!

Please add "under load" to your subject line. Usually if turtle mode is triggered, it doesn't turn off until the pack is re-chargged. But in your case the light comes on under high load with a full throttle and with the Heater ON, then turns off when you release the throttle. Try again wit...

Re: Battery Degradation

But the fact that the cells do not fall to the required level of 2.8 V is also caused by a bad cell ?? and what can be done now? It is believed that if you replace one new element, the device will stop charging, is it true? The car will shut down when only 1 cell reaches the low voltage limit, and ...
