Not expecting any epoxy issues, as the box was very tight on the frame without epoxy. The design means that the box sits on top of the top tube and is snug around the headset. Regarding the performance the Mac cruises at about 40kmph. The batteries sag about 7 to 5v at full current but give the...

deffx, See the link below for some info on the LG cells. Rated at 2C, 3 ahr each giving 21ahr total at ~ 52V http://endless-sphere.com/forums/viewtopic.php?f=14&t=52346 Cheers Matt

Deffx, Finally finished my build (nearly). Didn't end up welding to the frame but used epoxy to attach a alloy box. Bighits are a good donor bike. http://endless-sphere.com/forums/viewtopic.php?f=6&t=56221 cheers Matt

Inspired by Timmas frame welding I have 'upgraded' a big hit frame. The more I read and learnt about welding aluminium I became uncomfortable with loss of strength and need for heat treatment to achieve suitable yield levels. I had an alloy box build around the frame and headset with the aim of...

Hi Kepler, Inspired by your earlier build I have attempted to go down as similar root. Picked up an old model brand new Kona dew hybrid (with hydraulic brakes and flat bar) for NZD 350 and mounted a small befang in the rear. The large topeak dry bag is perfect for 18650s. Went for 12s3p of LGD1...

I have repaired the short and the BMS is no longer hot in this circuit. However it won't pass current when connect to a circuit. I bought thee at once and have replaced with another and all works fine. Photo below is of the faulty BMS. Cheers Matt

I think I have found the problem. There appears to be a short in the circuit for balancing the first cell. I will upload some pics shortly.

By -ve I meant the negative terminal. The balancing circuit on the first cell is discharging from that cell even though it is well below the balancing voltage. That circuit is too hot to touch. Also the bms it stopping current going to the controller. Cheers Matt

Hi I bought a D167 to run at 12s on a 16s board and have a couple of issues. I build a brand new pack from LG D1 all perfectly balanced at 3.77V. When I connected it up the channel on the -ve (first cell) got very hot and began to discharge this cell. Secondly on connection to the controller it...

Deffx, I have just bought the same bike and looking to make similar mods. Will either go with the 'box' option like you have or will replace the whole bottom tune similar to timmas builds. Did you cut out the existing bottom tube or is it hidden inside the box? Cheers Matt

Hi, A comparison between the Panasonic pd and lg d1 can be found at the link below http://lygte-info.dk/review/batteries2012/Common18650comparator.php The Panasonic cell is the enerpower + 18650 2900mAh 3C (Blue) I have bought 72 of the Panasonic pd cells from fasttech for a 5s14p pack for...

Hi, I built a 5P14S pack from these cells a couple of months back for a family member. He hasn't finished the rest of the bike yet so no real world results. I bought 72 cellts from fasttech for ~$7 each deliverd, the price is now around $6. I had 1 spare after repairs were made to a demaged...

Hi guys I went for the Panasonic NCR 18650 PD, 2.9ah, rated for 10A continuous discharge. My pack is 14S5P giving ~ 15ah @ 52V. This bike it is going through a cellman 40A 12FET inferion controller. While the C rating of PD cells is lower than the Samsung 20R’s, the Panasonic C rating is high...

While trying to find out more about NCR cells, I stumbled aross a shop ' FASTTECH' They have 2 x Panasonic NCR18650PD cells for ~ $15 with free shipping They use Paypal and a quick Google search didn't come up qwith any 'scam' type warnings or reviews...

From the info here these cells look promising to me - They are relativly energy dense, safe ?, can be made made to form a triangle or other shape and have a C rating that is useful for most. Also a supplier who will do most of the work to make a useable pack. A couple questions, What is the...
