Hi all,

So, ive gone and got a 2s2p thunderpower 4000 lipo pack to use as a RX pack in my x-spec ( i got it from skyline's here in the uk).

I am trying to charge it using a schulze 330 charger (ver 8.06 softwear) and i keep getting an error message.

Ive got several powerflite li-ion packs that i charge fine on the same charger but when i connect the thunderpower pack up the charger errors saying wrong cell count.

I am using the lipo charge mode and set the no. of cells to 2.

The pack is brand new but the off load voltage is only 4.5 volts. Is this normal or is the pack faulty ???

Cheers
Tris

I am no expert on Li-Po cells, but when i charge mine, I always check the voltage before charging.
I am fairly sure that the voltage of each Li-Po cell, should not be allowed to drop below 3 volts, If it does you will damage the pack beyond repair. Your pack should indicate at least 6 volts.
It does appear that the pack is damaged.
Hope this helps.
