Title: really need a charger schematic for my nimh battery pack
Post by: superchiku on April 06, 2008, 11:54:40 AM
well battery packs arent available in my place , so i have to buy 5 aa nimh batteries and make a battery pack myself , the problem is off course charging , coz i can charge 4 of them with the charger i bought but the last one cant be charged alone so i need to make my own charger to charge all of the 5

so any of u have any schematics for charging 5 aa nimh batteries do plzz share them so that i can make my charger myself and solve my problem...


THANKS FOR ANY HELP IN ADVANCE....

lithium ion batteries need special chargers and be careful when using them , too high voltage and kaboom!

Depending on the battery you might also need a balancer as well as the charger.
