Help, I need an EE
@Scorpio64 Just for reference: Max charge voltage for a lithium cell is 4.2V. You are charging at 48V for a 14 cell pack, at .5A. This is 3.42V per cell, and 1.71 Watts per cell. You should be just fine. Your Echo charger puts out considerably more current then .5A (it’s probably 2A+). You’ll be charging at a lower rate, which is good in your case, for safety. It will take longer to reach your voltage threshold for the pack, but it will minimize the risk of charging too quickly. In any case, I’ll reiterate, do this outside. Away from crap that can burn. Be careful! These batteries can hurt you. They are very energy dense, shorting the cells, charging damaged cells, or charging at too high a rate can have horrific consequences. I know that you know this, but it makes me feel better to say it again, my friend!

Help, I need an EE
Just watched the video. 48V will work just fine. You won’t let the magic smoke out of the charge circuit by pushing less voltage. Current could get you in trouble… I probably wouldn’t go more than 0.5A. I find the lack of cell balancing circuitry a bit baffling. Whatever you do with this…BE FUCKING CAREFUL!!! I shouldn’t have to explain the dangers of lithium batteries. Please do this outside and well away from anything that can burn. I’m really curious as to why they don’t have balancing circuitry built into that pack…

First of all, do you have a DVM?

48V might do. I’d have to see the circuit

She has quite a bit under her belt since commissioning in 1985. She held a lot of leadership positions, although that does not necessarily make one suitable for VCNO, or CNO. Certainly seems to me she’s been groomed for this position.- Close
