Hi I want to change the dead Ni-Cd batteries on my rechargeable drill with Lithium batteries.
It's 18v so i will need 5x 3.7v. The most cost effective way is to use 18650 batteries.
This requires a new charger for them. I have 2 options:
1. Make one
2. Buy an already assembled one.
The problem i face is that i can't find a charger with the money i want to spend (under 10$) that will charge them fast enough. If i use a charger like THIS one, it will take 5000mAh (my batteries) x5 / 5A (charger rating) = 5hours?. I need it to charge within one hour. I could get smaller batteries but i would like to avoid that if possible.
Another problem is that i don't know the max charge rate of the 18650 batteries but i hope that all Lithium based batteries have more than 5C.
Is there a way to modify a charge like the one in the link to be able to output 25A or i will have to make one (I have no idea how) .
Thanks
