Hello all,
I have converted a 1980 Kawasaki 440 LTD motorcycle over to a 8kW brushed DC motor.
Originally I set it up with (4) 12V 35AH SLA batteries. (very heavy & not much capacity)
Now, I am upgrading to a 2kWh section of a Chevy Volt Lithium ion battery. (less weight, more capacity, quicker recharge time)
I have done "tons" of research on this "battery" but, I could use some help on finding an "appropriate" charger.
Here is some info:
These batteries were made (for General Motors) by LG Chemical
The chemistry is Lithium Maganese Oxide (liMg204)
There are (3) pouches per cell & 12 cells in series (3P12S)
The cells are 3.7V (nominal) (x12= 44.4V (nominal))
The "safe" usable voltage range is 3.0V - 4.2V
...but, during my research I have found that, "to be safer" many are using them in the 3.3V - 4.1V per cell or 39,6V - 49.2V
From what I understand, this battery needs a "smart" charger or a charger with the top charge voltage "preset" at ~49V
but, most "48V chargers" have a top charge set at 54.6

Can the top charge be "easily" preset or adjusted on a battery charger?
