I have a 9.6V 2.2Ah Ni-Mh Batteries ! I plan to make the charging circuit on my own. I have known that a good charger must have the following properties:
1 - An Ideal charger must have supply constant currrent and should have a current limiter
2 - The constant current should be a minimum of 0.1 * battery Ah (Ideal)or maximum of 0.4* battery Ah(Maximum limit).
3 - The charging potential should be equal to battery potential ( maximum of +10% of battery potential )
any other parameters i need to consider ? and any links to good charging circuits ?
