There are 277 pages to that thread....
I would check out the thread before committing to building it.

Jay,
I would check this one out, it meets all of your requirements

I'm looking to buy a kit (or an assembled) battery charger for a 120v lead
acid
system, with an eye to upgrading to a LiIon system in the future (also near
120-130
volts, limited by my controller/motor combo).
Requirements:
-Must support customizable charging curves that I can tweak between Lead
Acid
and LiIon or differing number of cells.
-Must be able to auto-switch / auto-sense 120 vs 240 volt feeds.
Most likely, this will mean it has a PFC front end.
I specifically do NOT want to have to switch cables around.
(Ideally it will be able to limit draw to 15/20 amps on 120 and 30/40 amps
on
240...but I'm willing to toggle a menu option myself if needed for current
limit.)
-Needs to support a minimum of 2,500 watts of charging at 240 volts.
I'd prefer 3.3k or 6.6k, but 2.5k is a minimum. I don't really need a super
high
powered charger, but would consider a higher power charger if the price was
right. I
have a NEMA-14-50 outlet, so max of around 40 amps at 240 volts or 9-10kW
range.
Features I'd like:
-I'd like to keep the price low, and am very comfortable assembling a kit
of parts.
(But I want to be able to buy a complete kit, I don't want to have to source
parts
from all over...)
-A BMS input to turn off charging (I don't want to fuss around with a
separate AC
relay...)
-I'd prefer an open source solution over a closed source solution, but as
long as I
can manually tweak the battery charging curves and amp draw, I'd accept a
"black
box" that is cheap.
-Ability to have sdcard, bluetooth or wifi access to charge data logging
would be
very nice, but is not needed.
My maximum price point is around $2,000, and I'd really prefer to be closer to
$1,000, so I'm willing to trade power for cost as long as it supports 2.5kW to
3.3kW
charging...
Suggestions/recommendations/reviews or things to stay away from?
Thanks,
Jay
P.S. I currently have a 120 volt charger and a 240 volt charger that are both
designed
for lead acid, so I'll be saving some space by replacing them both, plus
gaining
flexibility for future upgrades.
