My Black Tidalforce iOX cruiser

I've somewhat attached my newly minted 36V 16Ah to my Tidalforce iOX 1000W electric bike. It runs beautifully and provides tons of sag-free power.I need to do a final fitting of the water bottle mount to the battery and she'll be ready to go!

Completed the 12S 10Ah battery

I thought I'd try something a bit different to see what would happen.

A typical replacement battery for my beloved Tidalforce bikes is a 36V 10Ah battery of some sort. I've tried sealed lead acid (SLA) batteries,power tool batteries (Bosch FatPacks), LiFEPO4 packs, and Ping packs (http://www.pingbattery.com/). All of which have their pluses and minuses.

Of course, my favorite as of right now are LiPO packs made from Turnigy Multistar cells. They are extremely compact, relatively light weight, and fairly inexpensive. They come in easy to configure package configurations and put out more than enough current to drive my favorite electric bike.

This configuration is a 12S (45.6V) 10Ah pack that is quite slim. The voltage is right about the maximum that the Tidalforce system will tolerate. Anything higher and the system will go into overvoltage protection (OVP) and shut down until the voltage drops below OVP. One solution is to not chage it up to its maximum voltage, which has the added bonus of extending battery life.

Anyway, here are some photos. I plan on mounting it to my bike's water bottle mounts this weekend and test ride it to see how it does.




I had some coroplast around so thought I'd make a sort of protective padding for the battery to see how well it works/lasts.

Another set of batteries for my Tidalforce electric bikes

The weather has finally warmed up here in the Washington, DC area and I've put together a couple of new batteries. This time they're a bit different.

The one on the left is a 36V 16Ah battery made from Turnigy Multistar packs. One is a 6S and the other is a 4S. Combined in series, they make a 10S or 36V pack. Perfect for the Tidalforce system.

The one on the right is a 12S 10Ah battery also made from Turnigy Multistar packs. This time it's 3x 4S 10Ah packs in series for a total of 12S 10Ah. The 12S has a higher max voltage than the stock Tidalforce motor will handle but if the battery isn't fully charged, then it should work. By not fully charging the battery and being careful with how far the battery is drained, the battery should have a longer life than one that is charged to its max voltage.

As you can see, I've not connected them in series and haven't added the Delphi Metripack connectors yet. More photos when I'm done. The 10S 16Ah will probably go on the TF iOX and the 12S 10Ah will go on my TF S-750C (for Crystalyte).

Very interesting solo wheel motorcycle!

I was watching Jay Leno's Garage last night and saw this vehicle. I couldn't resist taking a video of it and posting it here. I've seen photos of it before but never a video. it looks like it could go very fast!

My Tidalforce M-750X goes on eBay

This is my second Tidalforce M-750X that I'm selling on eBay. It's a lightly used, and I've replaced the front hub battery with a 36V LiPO battery made from Turnigy Multistar cells. Very light at around 5 lbs and very strong. I've also added a Large Screen Cycle Analyst V2.23 to the system to monitor the battery.

Sale ends this Sunday August 2nd.

New battery for my next ebike

I put together another battery for my next Tidalforce bike. This time it's a 10S pack made from a 6S and a 4S pack in series. I made an acrylic outer shell and Gorilla taped it together with an outer wrap of 4" gaffers tape. I need to do the wiring and the end caps next.

Google Photos Story - Opening up a dead Wavecrest Labs/Tidalforce electric motor

Google Photos uploaded some of my images and made them into "stories." Here's one to try out.
