Wall charger for rechargeable batteries HELP! Answered
Hi, I'm trying to figure out how to recharge these BATTERIES without having them blow up in my face. I'm very new to making my own electronics and a little timid when it comes to messing with batteries. I believe i need to use this DC jack connector? With this CHARGER? I'm using the battery to power 21 LEDS wired in parallel with resistors (3.4v 20mA) if relevant. I think i need to wire it up like in the picture.
I guess my question is if i wire all these things together and try to charge the battery will it destroy something?
Also if i wired two of these batteries in parallel can I still charge it the same way?
How do i know i'm using the right DC jack connector and charger?
Is there a specific switch i need to use?
Any help would be greatly appreciated!!!
