I currently own a Dewalt 60v Max chainsaw and leaf blower as well as their 40v string trimmer. While I regret the string trimmer, not due to performance but because it’s an odd man out when it comes to battery platform, all of my Dewalt ope perform very well. Unfortunately, Dewalt does not make a 60v Max lawn mower yet and all the reviews I’ve read about either their twin battery 20v or the 40v version are not very complimentary. The key issue is run time. One of the top contenders in the battery powered OPE field, for quality and run time, is the EGO brand. Any comments from experienced users in this area of OPE and your findings would be much appreciated.
One of the elements of this endeavor is issue of the battery platform. I find it interesting that it appears that EGO has only one size housing that they use for their 56 volt line and the simply add cells internally to increase the amp hour ratings. They currently seem to have 2.5, 5.0 & 7.5 Ah rated batteries. I’v replaced and repaired a few lithium ion batteries in the past and I’m wondering if the potted control circuit, located in one end of the EGO batteries, is the same for each of the three different batteries. If my assumption is correct I might be able to simply add cells to one of the lower rated batteries, up to a max of 7.5 Ahs. Any thoughts on this possibility?
