You should see DeWalt's 20/60v flex batteries. They are basically 3x 5s 2ah strings in one package. I think the charger does them in parallel but I have not tested that theory yet. The pack connection has I think 8 or 10 blades so the tool can use them 3s5p or 15s.ElectricGod wrote: ↑May 30 2018 4:52pmMost power tools do balancing in the pack or they have many small connectors to balance in the charger. The packs are not complex...5 or 6S at most so this is very simple to do. when you get into many more cells, then balancing gets lots more complicated. If you look at a lot of 40 volt chordless tools, they will use 2 batteries so that balance charging stays simple.wiredsim wrote: ↑May 29 2018 2:35pm
The biggest problem I have is I need to make this easy to use from a battery connection and recharging standpoint so no one has the excuse that it is too complicated to use and shirk their mowing responsibilities. I have new found appreciation for all the work the power tool companies put in to making these things dummy proof.
you can stay easy and fool proof if you use an onboard balancing system that no one but you has to think about. If all your family has to do is plug in to charge, they will see your electric mower as easy to use.
The DW790 brushess miter saw uses 2 of them for a 30s ~120v.
