X P4c is a professional compa ble intelligent charger, which is
compa ble with 14500/14650/16340/17500/17670/18350/
18500/18650/18700/22650/25500/26650 3.6V/3.7V rechargeable
lithium-ion ba eries and AAA/AA/A/SC/C rechargeable Ni-MH
ba eries.
Xp4c has the ba ery-type recogni on feature-based on the ba ery
type, the charger could choose the different charge method
automa cally. For 3.6V/3.7V lithium-ion ba eries, XP4c adopts
three-phase charge method (TC, CC, CV); for Ni-MH ba eries, XP4c
has the trickle charge and pulse charge plus the 0

any other slot with real- me display of ba ery status and intelligently
charging.
For the memory effect of Ni-MH ba eries, XP4c's CH1 slot has the
specialized discharge func on that intelligently helps to repair the
ba ery capacity.

The XP4c uses a high efficiency DC - DC step-down circuit,
which can greatly reduce energy loss while resul ng in a more
reliable, safer, and efficient charger. In addi on, the XP4c
provides reverse-polarity and short-circuit protec on.
①
Two charge current op ons (4*0.5A
、
2*1.0A)
allow you to
choose a suitable charge current to balance charge me and
ba ery lifespan. The XP4c uses a so -start func on, to avoid
damage from large charging currents when charging starts.
In addi on, the X P4c has ac va on func on, which helps to
repair the over-discharged ba eries.
