XTAR XP4 Full Set

Professional Li-ion/Ni-MH battery charger with four independant channels featuring three optional charging current (0.25A / 0.5A / 1.0A)

• Can charge up to four 10440/14500/14650/16340/17500/17670/18350/18500/18650/18700 or up to two 22650/25500/26650 3.6V/3.7V Li-ion batteries
• Can charge up to four AAA/AA/A size Ni-MH batteries or up to 2 SC/C Ni-MH batteries

For different types of batteries the XP4 adopts different charging methods:

• For lithium ion batteries, XP4 adopts three-stage charging (TC, CC, CV)
• For Ni-MH batteries, XP4 adopts pulse charging and 0△V,-△V judge method plus stopping charging when overtime and over voltage function
