Jay,
You may want to look at this charger for sale from Thunderstruck:

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.
