Custom Battery

Rabbit Tool WEST is dedicated to manufacturing NiMH battery solutions tailored to the specific needs of our customers whether we are producing hundreds or only one. We provide quality solutions at a competitive price with rapid response time.


We specialize in creating and repairing Nickle Metal Hydride (NiMh) battery packs. They have an energy density that approaches Lithium Ion batteries, but are very stable and unlike Lithium Ion, have no travel restrictions.

M Cells Available

We are one of the only companies in the USA that stocks and uses high capacity M Cells. They are the highest capacity NiMh battery on the market right now and are perfect for many large scale battery packs.

Our extensive knowledge of NiMh battery packs allow us to quickly create a brand new custom battery pack for your application.


We have produced 12-48 volt NiMH battery packs for dive scooters, assembly line robots, power antennas, lights, unmanned specialty robots, hazardous duty robots, remote camera operations, bicycles and custom power management solutions all for customer designed applications.



Much of our business is to replace cells in packs that others have built. If you want new cells installed, we refurbish the pack to "like-new" condition.



We take testing very serious and do thorough testing on each pack as it is being built. We have specific check points that each pack must pass before the customer even sees it.

NiMh Pack Care

Excercising NiMh Batteries

NiMH batteries have no memory effect like other batteries, but they can lose capacity if they are not used often. To prevent this, we recommend you periodically "chemically exercise" the entire battery. Discharge down to about 1 volt per cell or until the controller stops.


DO NOT just "exercise" the atoms nearer the reactive surfaces via shallow charging and discharging.

By doing this deep discharge and recharge "exercise", you will increase the life of the battery pack.
