Item Number 321695466967
I have 6 boxes of 20 x 7.2v 6.5A Nimh battery sticks taken from Honda Hybrid IMA Packs.
Each stick weighs just 1kg~ and is made of 6 D size cells welded together and then shrink wrapped.
They have simple 6mm bolt connections on the end for very rugged interconnection. They cannot be easily separated so your application needs to be suitable for the voltage combinations. I do not recommend parallel connection of sticks, but series connection is fine and the sky is the limit as far as voltage is concerned.
These sticks are used and have been removed from failed IMA packs, but they still have a lot of life left in them for other uses, including electric bikes, electric carts, power tools, emergency lighting, car booster starter etc etc
The picture and the YT video link below shows two sticks I bolted together to make a simple 12v battery booster for a normal car. Kept charged up in the garage I can use it to jump start my normal cars in a matter of minutes.

The Honda IMA Cars are very fussy about the battery and once it is not perfect the car electronics rejects them even though they have lots of life left.
The sticks are sold in packs of 20 (1 box) You get a random selection from my stock. They have not been tested in any way and are sold as seen. From my historical testing each stick will give at least 5ah at a decent current drain, most will give more at moderate loads of upto 1C.
The sticks are designed for a very harsh working life and can tolerate upto 100A Discharge and 50A charge currents.
This second YT video shows a random stick under 100A testing on my electronic load.

You can have sticks with or without a special ptc heat sensing strip fitted alongside to enable cell failure detection. (While stocks last)
I don't recommend them for rebuilding IMA batteries, but having said that each box will contain a proportion of sticks that are good enough to be used with careful selection and testing.
The sticks can be very simply charged using constant current 300ma led power supplies.
One such as this will charge a single stick.

Due to the weight each box is 22kg they are collection only. No postage.
