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.

Pictures of Turnigy Multistar LiPo packs (6S 16Ah, 6S 10Ah, 4S 10Ah)

I received the two Turnigy Multistar 10Ah (or 10000mAh) LiPo packs from Hobbyking recently. I ordered a 6S 10Ah and a 4S 10Ah pack. This joins the 6S 16Ah (or 16000mAh) pack that I already had. The 10Ah packs are significantly smaller (go figure!).

New Tidalforce M-750X bike sold!

A very nice gentleman bought my bike! He will have a friend pick it up so I don't need to pack and ship it, which is greatly appreciated.

I hope the new owner enjoys his new bike!
