Show off your lipo setup!

here is my 18s2p or 12s3p lipo setup

Since my original reply here:

I have setup and tested the removable AmmoCan RC LiPo setup on both CrazyBike2 and the Fusin Test Bike. It would also work fine on DayGlo Avenger but has not yet been used there except for a test ride. This is a 7.62mm-type ammocan, and contains 14s2p, using four 6s and two 2s, which is perfect for at least 20 miles on the Fusin Test Bike, even hauling a trailer full of salvaged stuff in a headwind if I pedal, too.

A second similar but larger ammocan (50cal) is now mounted to CrazyBike2 with a larger pack to support it's 4KW+ burst mode and still have longer range.

Charging is just bulk charging, with occasional balance checks both when it is in discharged states and during charge and after full charge, and so far there are no unbalanced cells at any stage: all cells within a few hundredths of a volt of each other. Charger itself is a simple typical ebike charger, 4A max, from a clearance sale here on ES, and I think it was $10 shipped (I got two different ones for $20 shipped; the other was adjusted for the voltage CrazyBike2's pack is at). I didn't even ahve to adjust it's voltage, IIRC.

and a pic of the whole bike (which has changed a little but not much since this pic, mostly adding much better lighting):


and a pic of how the green pallet-straps (salvaged from stuff tossed at work) hold it on the rear rack (which works ok, has had no problems, but would much rather have it in the frame or on the front of the headtube, if I could mount it there).




It is held from sliding aroudn by 4 velcro strips, fuzzy on the pack and hook on the rack:


And a pic of it mounted on CrazyBike2, in the formerly open center section:

Mounted on DayGlo Avenger for testing:

Would've been much better if mounted to the side of the rack support, down low at axle height, but I've had way bigger/heavier loads on that rack that caused me much worse riding issues.

15s2p 10ah + 2s4p 8ah pack for lighting

[icecube57]

20s 84v 20AH Turnigy 20-30c 4s Hardcase Lipo Charge in parallel... discharge in series... everything has been capacity verified and the packs have been tested. I spot check with my cell log... im still popping the packs cherry less that 10 cycles... Ive only balanced the initial 2-3 times while verifying capcity. I balance charge the groups individually and bulk charge the packs with an EP Buddy 6 to 1 cable... It works for me.. Its a little heavy but it sure packs a hell of a punch on the bike. I have a lyen 12 4110 12 mosfet controller programmed to 65A and it sure does fly.

My 24s pack

I want to build a lipo setup with some RC packs. In researching I realize there are a lot of options with regards to rc packs, chargers and balancers... Show off your pack! What charging method do you use, what cells, what chargers etc. Include some pics if you can...I don't read so good!!! Moos

See my saga thread below. Labeled pics, a complete build manual. FYI, these are not "RC" lipo - they're A123 AMP20 prismatic pouch cells, which are part of the lipo class, better than RC. Granted RC lipo will yield a lighter pack, but that's the only advantage in a head-to-head comparison.
