Battery supplier/builder wanted EU/UK preferably

Afternoon/Evening/Morning All, I am at the stage where I need a new battery pack built for my astro 3220 tangent powered bike as my lipos just wont balance any longer. It's time I bit the bullet and went for a bms controlled 18650 set up. I am looking for some help finding either a builder or pre fa...

Re: Tangent Motors RC mid drive kit

Dave,

if you could have any battery for the 3220 set up which would you choose to handle the amp draw?

I am considering an 18650 (not sure on which ones yet) build but can't help but wonder if they are truly a better option than quality lipo bricks with a high c rating....

Thank you

Re: Sturmey-Archer 5-speed hub, it's real!

Still going strong, it's in a new much heavier build and seems ok but then my batteries are on their last legs and I'm barely pulling 2k watts peaks.

The Tangent only puts out roughly human levels of torque but at higher rpms.

New batteries will see how much it can really take.

Re: Dave's 80:1 RC mid drive kit build log

The transplant. Modified to fit. Finished the chain tug today. Just a few tidying bits left to go. Tangent kit is versatile as hell. 2018-09-09 17.42.42.jpg Still need to sort cable ties and key cover and eventually a wider rear rim and of course a much better battery to truly unleash this beastie.....

Re: Another Stealth bomber (clone) build

Thank you. Off to find a dnm shock now:) It looks to be coming together nicely. I finally sorted a power switch for mine in the form of an antispark xt90 loopring key. Now to wait on the new renthal bars and stem and I'm good for a peoper test run. I still want to build a hubbie bike and you are add...

Thanks,

I wrote the 5ohm value as I thought the xt90 anti spark connectors had 5.6 ohm resistors in them?!

Re: Battery isolation switch with pre charge anti spark question

Hi Amberwolf, Thanks for the reply. The 120amp is just the maximun the talon esc will draw under load, I imagine the average is probably somewhere nearer 50amps. Great to know your standard isolator is working well!. Apologies for the drawing. I was imaging something like this for the pre charge cir...

Re: Another Stealth bomber (clone) build

Thanks, I've been holding off buying one as I wasn't sure of the bolt mount width...would suck to buy it and find it doesn't fit!

If you get a minute would you mind measuring how wide your rear shock mounts are on the inner face?

Re: Dave's 80:1 RC mid drive kit build log

I have been doing some reading...please correct me if i am wrong and about melt my face off: For a non arcing power switch/breaker it needs to be able to pre charge the esc before the full current be allowed to flow: this happens with the xt90 anti spark connectors through a c5ohm resistor bridging ...

Battery isolation switch with pre charge anti spark question

Hi All, I am trying to work out a basic on off power situation for my bike (running 3220 and CC HV120 esc so pulling about 120 amps give or take). Now forgive me as I am more a cut and weld kind of guy than an electron flowing guru. As I understand it, using something like a boat or car battery kill...

Re: How-To: Anti-Spark XT-90 Loop Key

Old thread but wanted to say thanks and if anyone is still watching this I assume this could be done with a simple lipo series connector and just use the loop key to finish the circuit?

Re: Another Stealth bomber (clone) build

I'm the wrong person to ask about hubs and hot motors as my knowledge of electronics is hilarious.

I've read some posts about cotroller settings being off affecting noise and heat?!

Re: Dave's 80:1 RC mid drive kit build log

Bearing sorted...found a uk supplier of white freewheel and bearings so got an enduro for half the price the others wanted. Replaced but still concerning amounts of lateral play. Meh. Love that Russian build. Alfine 8...been running my 3220 through it for over a year and it is holding up just dandy....
