Having controllers with dedicated LVC trip-points embedded,
when the available chemistries can conflict, is a real hassle.
Manufacturers try to sell product for dedicated series counts,
like 36V/48V, and leave out any chance of using non-standard
series-count builds from surplus sellers because of this.
They NEVER include a choice of chemistries,
so we're all basically all screwed there...
I have several battery chemistry packs I'm comparing, as example,
and I have had to mod my controller with a rotary switch,
to just compare these battery packs to each other.
I don't even know why modern controllers have this function,
it is, and should always be, governed by the BMS anyway...
I've since gone to inexpensive controllers that handle
ranges instead, like 6-50 volts, to test everything now.
(CNC Spindle controllers as example...)
Good controller makers like EBikes.CA provide us
with programable LVC threshold's, thank god,
but the are far from inexpensive.
My above unit costs me under $20 from China,
the later well over $200 + S&H, see my point ?
Please share any popular LVC mods you've found,
or Models/Links to units that are budget friendly.
Thanks
