Good news, a package from Hong Kong arrived today (less then three working days from China to my door - pretty good). The motors look very well made and finished, particularly given the low price (about £25 each). The machining looks very good and the stator windings are even and nicely encapsula...

If you don't want to reverse the direction of one of the motors, then you could look at arranging them in a staggered stack, both facing the same way and driving the shafts through chains/belts of different lengths. You might be pushed for room a bit with this approach though, as the Mini has inconv...

Shame about the auction, but if you email Ping directly on his eBay contact address he will give you a quote and supply direct - he'll send you a PayPal invoice directly. Whether or not this battery will solve your hill climbing problem depends on whether or not the battery is the cause (I've just r...

You're right, you can't just connect both negatives together, bad things may happen! The Ping battery comes with a battery management system circuit board strapped to the side, which controls both charging, by making sure that no individual cell gets over-charged, and discharging, by making sure tha...

It is a bit of a curious thing to try and unravel, all this legal stuff on lights, so no apology is needed. I managed to download a copy of the SVA Inspection Manual (albeit a draft issue of the current one) over the weekend and there seems to be precious little about lights, other than stuff on vis...

I've been running a 36V, 10Ah Ping LiFePO4 battery on my recumbent for about 6 months. Previously I'd run it for a very short time, when testing, on a 36V sealed lead acid battery pack. The LiFePO4 pack is astounding by comparison. Virtually no voltage drop under load at all and much more current av...

just a shame it's going to take a while to get them here from Hong Kong!


Not too long, I hope. I got an email this morning confirming that the package has left Hong Kong. With luck they might be here by next weekend.

Thanks for that link, I'd come across Ron's name a few times on some of the RC groups, whilst researching motors and controllers. Well, I've taken the plunge and ordered a pair of Tower Pro motors, rated at 2800 watts maximum each. Including shipping from Hong Kong they have cost me £77.10 for th...

Interesting ideas. I've long wanted to build a very light tadpole style trike, hence my interest in looking at these very light motors. I think I'm inclined to stick with RWD, as it's easy to do with a chain or belt drive. Although making a space frame or monocoque frame would be straightforward eno...

I'd be interested to see any legal advice you can get, Kelvin. Those used to dealing with SVA inspections might be best placed to know if there is something I've missed. I've spent a couple of hours or so reading through the C&U regs and the Lighting Regs and I can only find the approval require...
