Burp Battery Charger Kit for Ni-Cd & Ni-MH

Assembly Required

Refer: Silicon Chip Magazine March 2014

This versatile Ni-Cd and Ni-MH charger can charge one single cell or up to 15 in series connected cells (i.e. up to 18V). Features fast charge, top-up, trickle and "burp" charge options. The rapid alternate charge and discharge "burp" process reduces pressure and temperature build-up in the cells, and as a result, increases the charging efficiency. Built-in safeguards include temperature sensing of the cells to prevent overcharging.

Features:
* Adjustable charging time-out
* Adjustable dT/dt (Temperature change rate cut-off)
* Adjustable charge current

Kit supplied with double sided, solder-masked and screen-printed PCB, die-cast case (119 x 94 x 340mm), label and electronic components. Requires a power supply that can supply 1.8V times the number of cells in the battery, max 2.5A.
