To be honest I dont like your charger choice one bit. There are two reasons:
1) You will have to charge your pack in steps - 3 steps - that sucks and leads to imbalance. Dont even think about taking your pack apart to charge in parallel and discharge in series. This always, always, ALWAYS leads to mistakes that cost you a lot of time and burnt fingers.
2) That charger is only 200W. 66V 10Ah = 660Wh so that means it will take a minimum of 4 hours to charge your pack. More likely much longer. 750W is a nice charge power.
I understand you are making due - but please try to get away from changing pack configuration to charge ASAP. At least 1 in 3 of my customers who try this end up making a big mistake. At least 2 in 3 make a small mistake. Take it from a guy who has burnt the skin off his fingers many times..... and I dont make mistakes.

Kinni420 wrote:im spent the day burning my brain trying to figure out how to go from series to parallel for charging. Im pretty smart but wtf? I could use a lot more wires and some switches, would rather not. currently working on a pattern for building a battery/controller box in the triangle out of plastic. Ill post some drawings later
BTW methods wife kit is on the way to my door.
Voltage Cutout: A low voltage cutout is used to protect a battery pack from being discharged too deeply, which can cause cell reversals in NiMH/NiCad packs, permanent cell damage in Lithium packs, and sulfation in Lead Acid batteries. The programmable low voltage rollback allows you to set an appropriate low voltage point tailored to your pack.
Kinni420 wrote:I understand the whole series vs parralel thingy, its just how do you get around switching from series to parallel? I mean with 2 chargers, Im looking at charging three batteries per, all in parallel; when Im running 2p during discharge. seems like I have to unplug everything from the discharge harness, then replug into the chargers harness? I read your lipo charging post cover to cover twice. and I dont recall you showing anything about building a balancing harness. (if its possible).
great stuff to see it step by step btw.
doesnt the Cycle Anylyst work somewhat like a BMS? And im smart enough to know to shut it down before minimum (65.7)

Id love to see pics of everything...I already built the charging harness today exactly as you laid it out. with every single part. I also got lucky today and found this lamp/ alligator clip wire holder for 3 bux in the thrift store. ill get a pic tomorrow. looks like a robot or something great for soldering.
I have a ton of this wire. http://www.jr.com/monster-cable/pe/MC_OMC500/ all 12 gauge. as long as Im not an idiot and cross colors (I would probably die of embarrasment anways) would it be good wire to use? seems like a stupid question to me lol.

btw I never noticed the polarity thing on those AC wires. Learn something new every day. Monster Cables are designed to handle up to 10000 watts I believe? although its very flexible so I really dont trust it. Think I'll research some better heat resistant 12g wires.
I braid all my wires. Since my background is really in 60-70's car wiring, boat wiring and rock climbing Im very used to creating harnesses and knots (but only 12v with boats sometimes going parallel on a '1-both-2-off' switch), i solder a lot, and get the DC thing. never had to deal much with 24v systems in vehicles except for snowcats, which i only drove, not worked on. still i want minimal resistace from a connection so if i could use gold wire, solder and connectors Id be happy but................
btw explain "wicking" more on the post...its fun to watch and makes a so-so connection into something to celebrate. I could hang my bike from that 3 to 1 connection.
need a triangle bag before i learn to sew and make my own and start my own business.
Goodbye Davy Jones, I loved ya.
