I bought another BMSBattery 12 MOSFET 500 Watt Controller and it arrived yesterday. Although it has the same title as the controller I purchased and reviewed last year, it is NOT the same controller that I previously purchased and reviewed here: viewtopic.php?f=4&t=13691
This controller is available for 25$US from http://www.bmsbattery.com/
You can also find it on eBay by searching for the eBay username ecitypower. Shipping may seem a bit expensive at 24 $US but they use Federal Express (at least to the USA) and it only took THREE DAYS from Guangzhou, China to NE USA and this included Saturday and Sunday!!! I had the tracking number and was amazed that it kept moving over the weekend and arrived Monday morning. It was shipped LATE Friday evening just before midnight.
BE WARNED: Communicating with these people can be an exercise in frustration. It may depend on who you get as I sometimes get very clear responses and at other times it's obvious they did not comprehend what I was asking.
I have been running the older model of this controller at 60 volts @ 25 amps (1500 watts) for over 6 months with no problem feeding a gutted 350 watt Bionx motor. After three failures of the internal Bionx controller (inside the motor!) I had enough. I brought three phase and sensor wires out of the motor and called it good. I am presently running the system without the hall sensors. Only the 3 phase wires are hooked up. I have no idea as to whether or not the controller I just got will work as well or not. Only time will tell. My main purpose of writing this review is to alert everyone that what is being sold now is NOT the same as what I reviewed here: viewtopic.php?f=4&t=13691
It looks like the controller still features regen braking which works VERY well on the older model. This model appears to add EABS but it looks like cruise may be missing in the newer model.

Note: Not all the MOSFETS are the same in my controller???
They are left to right as follows:
1 = T430 BV941N
2 = T430 BV9413
3 = T430 BV941N
4 = T430 BV941N
5 = T430 BV941N
6 = T430 BV941N
7 = T430 BV931C
8 = T430 BV941N
9 = T430 BV9316
10 = T430 BV941
11 = T430 BV9413
12 = T430 BV941N
The T430 is probably some kind of date code. However, so far I can't seem to find any info on these devices. Anyone have a clue?
===== UPDATE:2010 July 28 =====
T430 appears to be the device number.
Thanks go to mwkeefer for figuring this out
^^^ Water seal gasket. Looks and feels like a sheet of clear silicon rubber!
Capacitors are rated at 63 volts I'm going to attempt to run this controller as the same voltage I'm running the older model at. (60 volts)
^^^ Click to enlarge! All writing on the board is legible when viewed full size.
I will add more info after I run some tests.
