[AUSTRALIA] Custom made 18650/21700 Batteries

Post by Cowardlyduck » Jun 28 2019 7:19pm

Hi all,

I guess I better make it official since I've done a bunch of these already. Below you can see a few of the custom made packs I've made so far.

Here is the one I build for an FUTR Alpha earlier this year:

This gave the bike up to 200km range! :shock:

Here is a series on building a 2.3Kwh battery for a FUTR Beta:

I also built this 2.5Kwh battery for my own Fighter:

And I built a long pack for my recumbent commuter:


Pricing is calculated based on a lot of factors so can be a bit hard to predict, but as a rough rule of thumb for the base pack I charge:
Pack WH / 2 + Parts.
For example for the Beta pack above this works out to:
20S9P - 74V/31.5AH - Sanyo NCR18650GA 3500mAh:
Parts:
* 180 cells: $1296
* Nickel strip: $19
* Wires: $29
* Connectors: $10
* Glue, Tape, Heatshrink, and Padding: $29
* Battery Medics x 4: $71
* Female/Male Parallel port + fitment: $165
Labour:
* 2331Wh Battery / 2: $1165
TOTAL: $2784 AUD

Note: As the Australian dollar is quite weak currently, parts costs are likely to be higher.

For BMS solutions I prefer to offer the pack with no BMS and balance leads and can offer a battery medic balancing solution as seen in several of the builds and example quote above. I'm happy to add BMS for those that want it, but will not be using cheap BMS solutions that risk destroying the pack.

Shipping within Australia is reasonable, but international shipping can be a bit ridiculous. That being said, for some it may be worth it if you need something highly customised and can't get it anywhere else.

Because every build is different I don't have all the supplies ready to go and have to order them in prior to starting a build. This means the typical time from deposit to pack completion is 2-4 months.

I'm keen to build a huge pack for a Bomber, Hurricane and P7...then I would have made the worlds longest range packs for every Stealth option. :D

Flick me a PM or email to ebikegarage@outlook.com to discus options.

Cheers

Hey CD, I was just looking at your Fighter battery, that is alot of battery!!!! Did you have to modify the frame to fit that battery in there?

Hey Rick,

Nah the Fighter battery was built to the exact dimensions of the frame opening. Maximum possible capacity that can fit without modding the frame.
I'm not keen on loosing my lifetime frame warranty, so any drastic frame modding is out of the question.

The Beta battery above on the other hand did require some frame 'corrections'. I wouldn't say they were even mods as the only reason the battery wouldn't fit was because the frame had a lot of factory imperfections and the opening was far from square/straight.

Cheers

Oh yah, I totally forgot about the warranty thing. Im on the fence with my next build. Which is rebuild the Bomber or build up my Alpha. The Bomber battery will not fit in the Alpha frame without increasing the opening. I like the Vboxx which is why I am leaning towards rebuilding the bomber. But I got this Alpha frame in army green just sitting there. Decisions?????

Well you can copy what I did above for your Alpha and you'll get a 3.25Kwh battery. :)

Or if your keen, you could build 2 at once to save total time/cost.

I'm currently looking into cheaper international shipping options. I'm hopping I can get the shipping cost below $500AUD. If that's possible then I should be able to compete with Stealth on replacement Bomber/Fighter packs. :D

Cheers

Yah, shipping makes it a tough market. I ran into this problem back when I was importing Crystalyte 5404 motors. I was pigging backing on a friend who had a dealer license so shipping to me was cheap. However, re selling and shipping around the world, I was only making about 20 bucks a unit and wasn't worth the head ache to do it. I got out because of that.
