Proper diagram is on ebay and, yes, you only use 10 wires.
Told you how to find it.
Did not post a direct link ... trying to encourage you towards not being totally helpless-hapless.
Tired of spoon feeding you and you spitting back at me.
Guess LC would rather listen to someone of similar ignorance and limited reasoning ability.
He should have read the next answer ... from a battery expert.
But reading beyond what he wants to "know" isn't a priority?
As explained to you many times, time the iron spends on the cell is the critical factor. 5 seconds seems the optimally recommended. Your 1st soldering video had you with the iron on the cell for, like, 5 minutes! Brief 800ºF iron does not sink deep to the sensitive plastic separator. Prolonged 600ºF...
Test all cells before combining into pack. Part of Step 1 is charging all to identical voltage. 2nd part of Step 1 is Let set several days then measure voltage to eliminate any with self discharge (especially important if reliable battery build desired!) Excessive heat from hack soldering job potent...
You are confusing charging different capacity cells in parallel (all identical voltage) vs charging different capacity cells in series (lower capacity cells charge and discharge faster)
Chargers charge batteries based on voltage, Ah is a byproduct. Batteries charged in parallel will all have identical voltage! ... how could you not recognize this concept? There is no need for a "pre-hookup cable" if batteries are near same voltage. Pre-hookup cable would be for connecting 42V batte...
Also my question about combining the SONA packs and the Samsung packs was not answered. The SONA packs were 4.0 Ah each and the Samsung is 4.4 Ah each. If I were to hook them all in parallel then the SONA packs could be charged separate from the Samsung cells. Run together and charged separate. 5p....
I still do not understand why the fourth pack was low in voltage. The max amount of voltage it will take after being on the charger overnight is 3.97V. I did get a refund for that pack and ran the pack solo to Wall-Mart approx 0,6 miles and 1.5 miles round trip as I went a different way home. Volta...
If you can't figure BMS pin out, check pictures on sellers listing.
If not there, do ebay search for same spec BMS, compare pictures, look for pin out pictures!
No disrespect but do not comprehend much about solder tips. I get the heat part and how the solder has to be liquid and a certain temperature to work. The only recommended use for thin pencil tips is for small precise connections. Unsatisfactory for larger wires or connections, insufficient heat ca...
Only in the past 2 years have I noticed any of the lower voltage cells in any laptop packs. Most are still "standard " LiCo. Mixing together, a few, has no determent except not taking full advantage of full capacity of, the "few". Just maintain a universally safe ≥3.70V static discharged voltage, me...
Some Squash and most Watermelons are nearly wiped out. Was too late spraying Squash with Neem oil and didn't consider the Watermelons, till the vines withered and began dying. Cucumber Beetle larva chewing at the roots. Neem oil is effective against CBs, when they are feeding on leaves, unfortunatel...
As the Hub Motor Turns and the LiPo Fire Burns. I know how to solder. :D I soldered 30 wires and connectors in the last 7 hours or so. I did it with the 60 watt iron and the tip it came with. I did not need the other tips. Larger "proper" tip is still so much easier, faster ... BETTER! Quicker with...
When testing same brand-model cells: If 1 pair sags .10V and another sags .20V ... likely, one cell is bad. Separate and test individually, either 1 cell is bad or both are poor. Use of "comparative IR" is to compare cells against same brand-model. "Cheap" IR meters seem inaccurate to ridiculously n...
3.6V vs 3.7V rated cells are rated as the average discharge voltage over the entire discharge cycle at a specified discharge rate. Factored are Internal Resistance (IR) and rated DOD Not as the discharged "empty" voltage, more a coincidence than a "rule", with older LiCo cells. Previously, not so im...
. ... Updated Quick Bulk Cell Testing Method Test cells the way I test used cells 1. self discharge Charge all cells to same exact voltage Let set several days Discard any with noticeable voltage loss 2. IR (Internal resistance) Comparative IR - identical cells under identical discharge will sag in...
Thanks for the awesome Wiki! QuNick question... what program do you guys use to determine size/shape/cell count/orientation of 18650 cell pack? I have a full suspension frame and need to get creative to pack as many cells in it as i can . No known "programs" Mapping Cell Placement Measure and draw ...
Harvested out about 8lb of Green Peppers, plenty more, mainly thinned the crop. Rather than posting a bunch of pictures, will link to Facebook page. Community Garden - OFP Just 1 pic - Peppers and Tomatoes doing well!!! Needing to stake up Peppers, too heavily loaded. This side of Tomatoes nicely pr...
. ... Split Tomatoes Tomatoes can split due to sudden occurrence of excess water-rain, especially at near ripe stage. #1 Best solution is to provide scheduled deep waterings 2-3 times a week. It seems to be the abrupt additional water that provokes splitting. Be sure to moderate added water if natu...
Sorry I haven't posted pictures, should have week 10 up tomorrow. Starting to see the first red in the Beefsteak Tomatoes. Harvested a few Cherry Tomatoes, several Yellow Dwarf Cherry and a few Yellow Pear shaped Tomatoes (beautiful and tasty!) Think I will have to thin Beefsteak, too cramped and ti...
Your build would definitely improve with a major gearing mod! OEM 450w gear reduction motor motorvates at ~420rpm Replacement is rated at 4500-5200rpm.
