    Samsung 25R/LG 18650HE2/ Sony VTC5 high power 18650 battery

    I bought some Sony VTC4 from Fasttech.com recently. They also sell the Samsung 25R. (http://www.fasttech.com/products/1420/10002357/1686801-authentic-samsung-inr18650-25r-3-6v-2500mah) With regards to prices: My Sonys were quoted at $6.16 if you buy a pack of two, $5.66 if you buy 10 or more...

    Another No Solder/Weld 18650 Build (Updated 03/09/2014)

    I found out since then that the NZ Post office has a service for cases like this. You get the company to send it to an NZ Post run office/warehouse in the US and they then onsend it to NZ. Shipping cost are pretty painful ($5 (US) from McMaster Carr to Portland OR and then NZD$31.50 to go to...

    Raged Focus Black Forest 29er MAC 10T 40A Build log!

    FWIW, About the hill. Its a pretty mild hill: elevation (as per pic) is about 2.3% going from left to right and its over about 850 mtrs and then its down hill anyway.

    Another No Solder/Weld 18650 Build (Updated 03/09/2014)

    I totally agree with you lfp, but none of the NZ based suppliers have any data sheets listing compression set on their websites, and the ones I contacted via phone were unable to provide solid info re compression set either. I have considered buying the same stuff that 'snath' used and...

    Another No Solder/Weld 18650 Build (Updated 03/09/2014)

    I looking to make one of these no solder/weld battery packs using some Sony US18650VTC4's which I have ordered and are on the way and have been looking around for the bits to make it. I have problems sourcing the Poron urethane blanket. (I'm in New Zealand). Would neoprene rubber strip work as...

    Another No Solder/Weld 18650 Build (Updated 03/09/2014)

    I really like this design and want to have a go at this for my first battery pack build. I'm looking to build a 14S5P pack but it has to fit into a specific size bag with dimensions of a bit over 220mm x 150mm. Since the battery spacer blocks are 20mm x 20mm it makes sense to go to a config of...

    Anybody try these hills on your e-bikes?

    According to Wikipedia, the steepest residential street in the world is Baldwin Street in Dunedin , New Zealand (http://en.wikipedia.org/wiki/Baldwin_Street) A 50 year old bike mechanic went up it with a 300W (max legal allowed in NZ) rated bike. He was pretty stuffed aterwards, but got there...

    Will my MAC motor run Ok on 7S / ~25Volt?

    I have a standard MAC (10T) motor and am looking to build an 18650 pack. Was going to make two 7S5P packs and run them in series so would end up with about 51.8V nominal and about 10.5AH. Then I was thinking this morning why not optionally make a harness to parallel them and run on 26V? Will...

    Question re Cycle Analyst (V2.3)

    I have a MTB with a standard MAC kit with the 25A 6Fet controller. I also recently purchased the Cycle Analyst V2.3 (also from cell_man) and I'm pretty happy with it. One thing doesn't seem to be working properly though: I've set the CA Max Amps to limit the amp to 15A. Yet after a ride Ive...

    New Zealand represent

    I'm from Auckland, and recently converted my bike. Got all my bits from overseas (cell_man and hobbyking for LiPo batteries) so don't know much about local suppliers, sorry. I found that getting the stuff into NZ (including batteries) was not a problem. BTW, nice looking scooter! Peter.

    my experience running LiPo on a commuter bike

    Like the OP, I run a commuter bike with a 12S 5AH little Lipo pack and have an ICharger 106B. And again like him, I like the bike and lightweight aspect of the Lipo, but not so much the "care and feeding" of the Lipo. There is the charging and all the palaver that goes with that and also of...

    Looking for BMS with adjustable HVC (and LVC)

    I want to make my life simpler (as far as charging my little LiPo pack is concerned) and am looking for a 12S or 14S BMS that will allow me to turn the HVC down to 4.1V and increase the LVC to 3.6 or 3.65V. Is there such a beastie?

    Ebiking is so fun its changed my life

    Ditto. I moved from Holland (where I grew up) to New Zealand many years ago. As you know, in Holland biking is the norm. And for the last 30 years or so, I have been wanting to get back in bicycling, but the hills just kill me to the point where I have to get off and walk beside the bike. So not...

    Recommendations for battery and phase wire plug/socket?

    I have a little 6 FET controller (25A) and am looking to tidy up the wiring because with the current multitude of plugs and leads it resembles a big bowl of spaghetti. :-( So I'm going to take it out of its current housing and install it into an aluminium diecast box with 3 sockets mounted onto...

    Some questions re LiPo, bulk charging and BMS

    I have bought a standard MAC kit from Paul (cell_mann) and I’m really happy with it (not in the least as a result of the good info and help from people on this forum). My battery is a 12S Lipo pack (3 x turnigy 4s 5000mah hardcase bricks) and I am charging it with a 106B Icharger which also...

    Fitting front wheel MAC to fork - a few questions

    Thanks for the advice guys. As it turned out the solution was obvious: I had bought but not yet fitted a grintech torque arm. So I looked at that a bit closer and thought "hmmm ... that has nice 4 or 5 mm thickness..." So I put the torque arm on the inside of the drop out (instead of the...

    Fitting front wheel MAC to fork - a few questions

    Thanks Ricky_nz. No lawyer lips (cheapo Diamondback bike from the Warehouse). Yes, I did buy a torque arm from Paul as well and will fit that next.
