    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    I've finally fabricated and fitted the Polycarbonate windscreens for my Karda EATSRHPV tilting trike. Roof, side panels and rear body yet to come. I haven't noticed much of an impact on speed at my normal commuting speeds on the flat but I lose a couple of kmph on fast downhill sections...

    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    It's not too heavy as it is made out of fairly thin-walled cromoly steel so it hasn't affected my top-end speed at all from the test rides I've done so far. I'm a little slower going up steep hills, but it is hardly noticeable. I'll be doing the weight calculations in the next few days once...

    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    The roll cage is now painted and looking a lot better. Once dry, I'll be fitting the roof panel and then the front windscreens and bolting the new indicator/mirrors back on and wiring up the rest of the lights and controls. I also replaced my old hub motor which was stuttering badly with a new...

    hub motor running jerky and going backwards and forwards

    Thanks for the succinct suggestions Alan. I'll target the wiring harness first and see how it goes. Here's hoping I haven't cooked my controller!

    hub motor running jerky and going backwards and forwards

    Hi guys, noob question here again - my 1kW 48V hub motor has started stuttering badly violently driving forward and backwards (!) in short jerky motions with gaps of no drive as I push my trike along the ground. A few years ago I replaced the Hall sensors in the hub and now some of the Hall...

    The major components of the roll cage are now tacked together to check out the geometry and wheel and foot clearances. I’ll have to take a break for a couple of weeks now, but when I get back will fabricate the windscreen and body panels. Later I’ll work on the rear body. eKOtjhWNc6Y

    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    Hi Macribs, the body is taller than velomobiles like Adam's as I'm aiming for a roofed design more like a combination of the Arcus: bryivcPH4BI ...and the TryTrike: FoPc1ezMHmM

    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    I bent the first B-pillar roll-bar into shape and tack-welded it onto the trike after two earlier attempts to get the right compound curves that would clear the front wheels at maximum lock and when tilting as well as clear the heels of my feet when pedalling. Quite tricky. I then managed to...

    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    Working out the overall profile of the roll-cage/body. I was originally going to go for fibreglass/carbon fibre for complex 3 curves to the body but with my current level of expertise, equipment and time I'm now thinking I'll take the easy way out and stick with 2D curves and hopefully end up...

    EATSRHPV-Mart's E-Assist Tilting Full Suspension Trike build

    Got an early birthday present a little while ago - a DJI Mavic Pro quad-copter that does a quite impressive job automatically following me on my trike: RvpMwI7WAXA The drone can be set to circle you as you ride or follow along from the side or back and has sensors at the front and bottom to...

    Is this Ping 20Ah 48v 32s 2P or 8s 2P?

    Thanks Dan, I think I've wrapped my brain around how it all works now. Looks like I was right to originally set the CA to 16s after all. Good to know!

    48v 20Ah Ping battery dropping from 19Ah to 17Ah in days

    Yep, makes sense. The vast majority of times I commute, I'll only be using up to 12ah so should be good.

    48v 20Ah Ping battery dropping from 19Ah to 17Ah in days

    That's good to know Dan. Understood. Makes a lot of sense. Thankfully only one cell swelled, the other 3 in the problem group all tested fine which is a relief. I don't think I've ever seen the max amps go higher than that 31 amps I measured on the unlimited setting - my mention of 40A was...

    48v 20Ah Ping battery dropping from 19Ah to 17Ah in days

    I do appreciate the feedback and advice guys. The good news is I specifically checked out the maximum current draw shown on my Cycle Analyst yesterday when going up hill from a standing start with the "unlimited" power setting (which maxed out at 1,590w) and the current never went above 31...

    Is this Ping 20Ah 48v 32s 2P or 8s 2P?

    Thanks guys. With 32 cells in each half-pack, 16S4P does make sense. I'll tweak the Ah rating setting and see if that fixes the inaccurate Battery gauge display on the CA.

    Is this Ping 20Ah 48v 32s 2P or 8s 2P?

    Sorry for the newbie question, but I wanted to double-check what the "S" rating on my pack is so I can set my CA v3 battery gauge to show the right fuel gauge display. It is divided into 2 half-packs each containing 32 cells with the cells in groups of 4 (I think they are connected in parallel...

    48v 20Ah Ping battery dropping from 19Ah to 17Ah in days

    Thanks for your suggestions Colin, 80% capacity is indeed quite conservative(!), not sure if I can be quite that disciplined! My daily commute is 26km to work and back so most of the time I would run the battery down to about 60% so that's not too bad. I do in fact already have the power...

    48v 20Ah Ping battery dropping from 19Ah to 17Ah in days

    After running the repaired battery for several partial cycles, I had the chance today to run the battery flat and it delivered an impressive 20.8 Ah, up significantly from 15.7Ah (and that was with my powerful lights and animated LED flag pole being used a bit and not being metered by my CA)...

    Dangerous to connect up battery w unbalanced cells?

    Thanks for all the feedback guys. I chatted with Li Ping and he confirmed the replacement cells were charged to within 80-90% of full so indicated they should be close enough voltage to mean connecting it all back together and leaving it on a long BMS-balancing charge would do the trick. I...

    48v 20Ah Ping battery dropping from 19Ah to 17Ah in days

    You are correct Dan, my 20Ah Ping battery is composed of two separate packs. The cells in each pack are in series, but the two packs are designed to plug together in parallel when fully assembled. I talked with Li Ping who indicated the replacement cells were charged to 80-90% full for transit...

    Dangerous to connect up battery w unbalanced cells?

    Hi guys, is it dangerous not to charge a replacement cell group up to full charge before connecting it in a battery pack back together with other already fully charged cells? I have just had 4 replacement cells soldered as a group of 4 cells into a 16s string of cells which is half of a new 48v...
