OK here it is: CMM 100 Black and Decker 24 volt battery powered. I replaced the original lead acid battery with a lithium ion battery with over triple the useable capacity and added a voltmer, ammeter, coloumb counter, and recently temperature guages to the motor and battery. The...

Added temperature guages to battery and motor (CMM1200) - see how hot it gets! I was curious to see how hot the battery and motor in my CMM1200 got. Since I installed the lithium ion battery, the motor works quite hard as the new battery is able to supply a much higher amperage than the old...

The battery is in, plugged into the motor, and ready to go. Just put the top back on and you are ready to mow. However, it would be wise to at least add a volt meter to get ideas of where your charge status is so you don't over discharge while you are mowing. You could just plug in something...

Now that the battery is built: 24 volt 30Ah from several 8.4v 60Ah, it is time to install it. First remove the original battery, and underneath it is very uneven so I cut a piece of plywood to size and installed it: Then place the battery. There was room to spare, so I put two inch thick...

So now you have a 6 cell 30 Ah 24 volt lithium ion battery. Lithium ion batteries are very sensitive to overcharge and under charge to the point where you should monitor each individual cell while charging to ensure that any one cell doesn't get overcharged during the charging process. For...

After 5 years of using the CMM 100 with its lead acid 24 volt 18Ah battery, I decided that it was time for an upgrade. After months of searching I decided on the Lithium ion (LiMn2O4/LiNiO2) used to power the electric car the Nissan Leaf. I considered both the NiCd and NiMh battery types, but...
