this requires some battery baby sitting,
if your cells are staying very well balanced then your voltage cut off

Wise words indeed. The price of a BMS is so cheap these days that it is
almost inconceivable not to fit one.

Thanks guys for the information. Ken and I are reaching out for help so
don't spank us yet for putting in something dangerous lol. In my case,
where I plan to use a BMS but want to reuse a lead charger, a BMS and
voltage cut-off so the charger doesn't just send amps to the shunts when

Hi guys,
I'm not trying to "spank" anyone. Just get them to look before they leap!
Did you ever have a (usually teenage) friend say, "Hold

Hi guys,
This is kind of long (I tend to run on, sorry). Please bear with me and
I'll eventually come to the point.
I'm sort of the electronics equivalent of a shadetree mechanic. I've hacked
(in the good sense) electronics since I was a teenager. ICs weren't really
available to hobbyists then. My e
Any charger has internal sensing of its output voltage. This is nearly
always in the form of a resistor divider network.
If you place an additional resistor in parallel with one of the
sensing resistors, you can influence the voltage that the charger
'sees'. Raise the apparent voltage high enough
