Almost ready to start testing. picked up an icharger 106b+, with CB1010 balance board. Still need to figure out which connectors to order to wire to battery/plug into balance board. Testing will start with 1 individual pack, leaving it complete with whatever built in bms it has. I'm...

An example of this strategy would be appreciated.

When I begin testing these, would I solder the 3 leads of each polarity together and use that, or do I have to open each of these cells to remove that board? I'm not sure if what I'm assuming is a built in bms based on a few online searches. I'm guessing it is a bms based on the labels on the...

Update- I picked up the batteries today. I carefully peeled back the covering and took some photos. Hopefully someone can make heads or tails of the board attached to them. breakdown: 1S2P 3 positive, all originating from the same solder point 3 negative, same thing. White wire originates...

That's great, because the info I've been reading is pointing towards $3-400, which is pricey but acceptable long term. Problem is I don't know if I have several hundred duds or not so I'd like to limit my up front expenditures until I know what I have.

Thanks very much for the replies guys. John, the provided wattage/amperage is only at roughly 3mph. WOT is 5mph, drawing upwards of 30 amps from what I've seen in testing posted by others of the same motor. I wanted a 15 mile range for the "drop me off at X, pick me up at Y" trips I like to...

I'd happily use either of the 2 cell types. If it'd be much easier to use the 1S2P 10,400 Mah, I would. I just trying to drum up uses for the ones I have (and recently sold the torqeedo so the timing was right for a new battery setup for the minn kota thats replacing it. Question- I see...

Yes, deck of a kayak, which previously ran a torqeedo 403 so I've never used a heavy marine or auto battery. The rig is a Jackson Big Tuna, and with my heavy self in the solo seat positiin I still prefer to put the battery up front. Hillhater, the cells will be TCL Hyperpower cells from a...

dilkes, Would the data in the link apply to the lipo cells I intend to use? I'd go with 18650's if I didn't recently purchase a manufacturer liquidation stock of over 300 lipo packs originally intended for tablet use. "If you are drawing a 180 watts for 5 hours continuously, you need 900Wh of...

Thanks for the replies guys. Use will be the front deck of a kayak. Likely enclosed in an aluminum or kevlar housing. The thing I wanted to wrap my head around the most is the rated Ah of a pack vs its actual usage Ah available if you're trying to charge to 4.15 V and discharge to 3.6...

Hello guys, I'd like to ask a question (or several) about the capacity difference consideration when trying to calculate how large of a battery you would want to replace a deep cycle marine battery. I understand that a deep cycle battery is designed for more discharge than a regular lead acid...

Looks good, I'm considering a rear hub one of these as well myself down the road. Does anyone know if it's possible to swap the front fork out to a suspension fork?

Will do, I guess its a waiting game at the moment. I'm assuming if 2 of the wires are for thermal readings that would be a good thing, right? This cell has twice the amount of wires as I'd normally expect right? EDIT**

John, yes with the volume of cells I have it will probably be in my best interest to get setup properly with gear. I'm following the thread you created and I'll hopefully get a clear picture of what I should have with relative affordability to get this project rolling. Hillhater, yes those...

I certainly would be happy to take that option should that be on the table for someone. My only question would be: based on John's and others' advice it seems like I'll need my own testing equipment to test each individual cell prior to pack construction. I haven't dove into the differences in...
