Can you tell me how I should count the voltage
Sku: BLDC-80

If I want 288v nominal and continous
should I go;
3.2v x 90cells = 288volts (is this nominal)
or
3.8v x 76cells = 288volts (or is this nominal)

About charging:

I have my eyes on the on manzanita PFC-20
2050$
what is buck enchence? + 400$
or Meter? + 250$

and how can I charge a pack of 288volts with a 110v AC wall outlet?
the charger just does it?

Hey Pirape,

3.2 volts is typically the nominal voltage for LiFePo batteries, if this is the chemistry you are considering.

Regarding the battery Ah rating you choose... you should evaluate the specific battery specs as they relate to the current vs time you expect to use in your application. example 90 Ah battery rated at 2C continuous is good for 180 amps.

The Buck enhancement option allows the charger to make more current when the battery voltage is less than the peak of the line voltage powering the charger. This option increases the power available below these voltage thresholds by about 50%.

The meter is just that...a meter which shows you how much current you are drawing.

Yes.... the charger is a rather smart little devil.... :p
