My new battery arrived today in time to play with it over the weekend.
Opened up the hailong case and appears to be 14S3P panasonic GA cells. Seems about half the size and weight of my old LiFePO4 rack battery.
Before ordering a controller, I thought I'd take a look at my existing controller. Turns out it is a Nine Continent 36/48V Infineron type 9 fet 22A controller. However it is marked as set to 31.5V LVC rather than 42V. When I bought the kit 5 years ago, I was told that the controller was only for 36V, but I guess the reference is to the hardwired LVC. I'm keen to give it a go, even if as a temporary measure until a new sinewave controller comes from China. Can I safely ignore the LVC, provided I keep an eye on my battery level?
If not, on the PCB there is an occupied point marked +48V that links off towards a cap (I think), immediately next to it is another point linked to the end of a 200 ohm resistor (only connected to the circuit at the other end). Would it be likely that a simple jumper wire between these two points will add appropriate extra resistence set it to 42V LVC?
There are also three other points in same row. One heads off in the same direction (towards cap), another links to a point alongside the other wiring points and the final one is a ground. I'm guessing these may be for an external LVC switch and I could safely ignore them?
If it works, I imagine I'll still have the artifical 32km/h limiter to try and hack. Is this linkly to be a hard wired setting, or software only? There are five programming connector points (though no pins).
Time for bed. Thanks in advanced for any suggestions before I potentially blow it tomorrow!
Will be nice to have power again!!
