Hello John,

The Hybrid Auto Center is where I bought the modules from.  I had them 
pre-balance all the cells which all came in at 3.9 volts.  I also got the Orion 
BMS from them which the assembly manual recommended a range from 3.6 v to 4.1 
volts.


I am using a Manzanita Micro PFC-50 charger that is set at mode 8 for these 
types of cells. In mode 8 or switch 8 on while all the other switches 7 to 1 
are off will not allow the charger voltage go above 4.0 volts.


My daily driving range is 2 miles, which is 1 mile up hill and 1 mile down 
hill.  Once a week, its 3 miles up hill and 3 miles down hill.


The number of cells and assembly was calculated on the maximum continuous motor 
ampere, which is 200 amps for a Net Gain  Warp 11 motor. Not battery ampere 
which is normally lower.


According to all the people at Hybrid Auto Center, Manzanita Micro and Net 
Gain, My motor and battery pack should have a easy life which could be more 
than 10 years my last battery did.


Roland

If you charge to 3.8V, you'll get more like 42AH capacity.
Generally, charge to 4.1V is considered reasonable.

Hybrid Cars, Batteries, EV Conversion kits, Toyota Prius ... Charging. Every 
cell should not go over 4.2V during the charging in any case.
