Charger

In September I ordered a Chinoz 144v/8a charger for LFP from evcomponents.com. After it didn't arrive for a couple weeks Dave Kois sent me a loaner Manzanita charger. I've been using that since but still wanted an onboard charger. Finally last week a charger arrived. On the evcomponents.com website the charger I bought was listed as 10.2"x10"x5" and the one that showed up was and Elcon 144v/8a with the dimensions 14"x7"x5.5". So, it wouldn't fit in the bracket I had built for it a few months ago.

So I hunted around for a place to put the charger and found one in the battery rack. When the charger was finally hooked up to the pack I got a "Battery Disconnected" error from the charger. Dave Kois said the charger wasn't programmed for my cells and he eventually sent me another manual with instructions shown below. When I pushed in on the LED/button, it went into the case of the charger and didn't effect the programming. So this one's going back to whence it came.


Choice of Charging Curve (curve 1~10)
1.The LED will flash red several times when AC is first connected, then the LED will flash green once. The number of red flashes denotes the present curve. E.g. If the red flashes three times, it means the present curve is curve 3.
2.To choose another curve, please cut off the power supply first, then unpeel the label, pressing the button while connecting the power. If you want to choose curve 3, release the button after the 3rd LED Flash. Now the selected curve (e.g. curve 3) will be recorded in memory. If you want the charger to work with the selected curve (e.g. curve 3), cut off the power and reconnect it.
3. Factory customizes 10 charging curves before delivery according to customer demand. These are 10 combinations of voltage and battery size for the same battery type.
