G'day folks,

just bought a new Hitec X4 4 port charger. Friend has one and he has been caning it with not a problem, seemed to be bullet proof so I bought one too.

Charged a 4S lipo pack no probs so then hooked up some other packs. charged at 1 C

• 2 packs of 5 cell, 6V, 2400mA/h Sub C NiCd - charged at 1amp
• 1 pack 5 cell, 6V, 2000 mA/h Eneloop NiMh - charged at 1 amp
• 1 pack 1 cell, 1.2V, 3600 D cell, NiCd - charged at 0.5 amp
• 1 pack 5 cell, 1100mA/h AA cell, NiCd - charged at 0.5 amp.

Charger works fine if only 1 or 2 ports are used, if I put 4 packs on at once all charging at 1 amp or even 0.5 A, then one port will go into breakdown. I can be any type of pack or port. I swapped packs, ports and leads around.

Has anybody experienced this before? According to the manual it states the charger has a fault. I am sending it back under warranty but would like to guage how common this problem may be.

cheers
Peter

I sent mine back and hitec gave me a new one............still does the breakdown on the new unit.........A electronics expert at out field after me describing the break down,said I should look for a Ground loop problem might be giving the NIMH or NICAD modes problems......mine also does 123 or Lipos with no problem. Ground loop problem sometimes were a pia on music speakers. Worth a look anyway.

Opps forgot to add mine does the breakdown on NIMH/NICAD anytime I hook more than one battery up at a time as soon as I put on the second NIMH or cad the first channel will trip into breakdown mode if I reset that channel the second channel will go break down......and both batts are same chemistry and amps.

so how did you go with the mythical ground loop?

I'm assuming he means an earth return issues on the mains side?
