I spoke about stripping the paint of my Lumenator. Well here is the pic. I think it looks much better.
In other news. I had a lipo incident that happened months ago but lets put it this way... one of the balance connectors on one of my packs was left unusable. The contacts were all gnarled and fused but the connector itself was fine. I just finally broke down and bought a replacement connector. So that should be in the mail.
After leaving my pack on the charger and leaving the battery medic on it over night for a few hours all my packs are like in a super balanced mood lately. While charging all my cells are the same across the board. When it goes up in voltage they all are within seconds of each other. Before it was bad. Taking 20 min between voltage changes for low cells to catch up. It wasnt far out of balance but you can tell it was over due.
Im chargin in a 1s 9p configuration. I have another 3 packs off to the side that I use when I need the extra AH on my ride but it stays charged ready to rock and roll.
I have parallel plug for charging and a series plug for discharging. Very fool proof even for a newb. You cant plug it in wrong.
Its hard to manage packs of different brands and c ratings and keep them all balanced together. I used to run all my packs individually. They sub sections were parallel at the pack level but not at the cell level.
I now charge and discharge my packs leaving the balance taps connected in parallel on each pack sub section. I have 3 sub sections with 3 packs in them for (3) 22.2v 15ah packs. There is another harness that parallels the three subsection at the cell level for charging. I use 1 medic to balance the entire 22.2v 45AH pack at cell level. They stay balanced way better.
Some of you may say one day you are going to forget to disconnect all the packs at the cell level when you series the packs at the pack level. I doubt it . Its happened once but it wont happen again. I dont ride or balance every charge cycle. Im just sorta conditioning my packs so i can slack off and ride more during the summer. But I go over my battery bag several times before plugging it into the controller I spent hours keying plugs and making it to where they only plug in one way. Even color coded labeling. I do all this prep work before I go on rides. I make sure Im not rushed and have plent of times. If its going to be a while between rides I make the pack ready to discharge to where all I have to do is grab and go.
I also bough some buzzers. I should use them all the time but Im going to use them when I know ill be past 2/3 of my pack. But reading GInDC experience with them it seems like they may kinda inaccurate at the alarm voltage.
I have the LVC programmed kinda high on my controller. I plan to wire the CA to hit the ebrake at a certain voltage.
Ive been reading and absorbing peoples advice. I have more capacity than I will use at one time. Even on my longest rides this year I basically got tired and ended rides early with plenty of power left on tap. It took me 1 1/2 hours to drain half of my 20AH pack and I was giving it the business playing around... Jack rabbit starts and what not. Its very good piece of mind that you have almost an endless amount of power on tap. Everyone should go out and look at their riding style and play around with the speed switches. Even though the CA gives you an account for how much you used there is a difference between simulator range and real world range. I know that my real world riding with varing terrain with 25-30mph speed my riding range is about 10 miles per 4 AH or around 26wh/m so a 50 mile real world range. But the trail by my house that has a grade of 1-2% grade either uphill or down hill I can get the range in the simulator cause it is perfectly flat...... almost. So i know my bike can get 5-6 miles per ah pedaling along so thats around 12wh/mi so i have over a 100 mile range. And worst case senario hauling ass my range is 20-25 miles at 50-65wh a mile.
I find that my ass cant outlast my pack. Thats what it boils down to. If you get this valueable date and scale your pack accordingly.
Since my packs are scaleable I can run at many AH capacities. Its easiest for me to run these 66/15 , 66/20, 66/5 although I can run 44v and 88v in different combos also. So know your range know the speed you are traveling know you AH consumption for the area and riding style and carry what you need and 25% more. Dont carry packs if you dont have to. Save the wear tear and cycle count whenever possible.
Thats enough ranting for tonight Now for my final though...
This is how I feel about my bike..... Well put by Jerry Springer...
