Have you ever considered making a charger that also functions as a batter bank / inverter?

Would love to use your batteries for backup in my home or RV. Have you ever considered making a charger that could accept AC input, DC input (from Solar) and then output to AC? At $200 for 7.5 Ah, your price for a lithium battery is pretty incredible. Would love to use them as backup for my house in the winter time and also be able to take them out of the charger / battery bank to use with my tools. 

Great products. Keep it up.

Herbert, where are you seeing 7.5Ah batteries for $200? Lots of people here would be interested! :-)

An inverter/power source is a popular request here. I think Ego would be wise to build it.

GREAT! Count Me In! Would love to make use of all my batteries during Hurricane Season. If Not, Atleast Usb Charging and Light. Would buy For two houses Fans, Lights , And Power converting Abilities wether that's USB or Inverter, I would Also Buy more Batteries. EGO please Consider.

This reply was created from a merged topic originally titled Professional Portable Power Source.

So I just watched a pretty neat video about a Bosch battery lawnmower system available across the pond...  here's the video:

https://www.youtube.com/watch?v=p8n6HLjD0XU

What a concept - a large portable power supply (battery) enabling recharging on the go for professionals who intend to use these tools on large jobs and/or continuously throughout the day!

Hey Ego, you want to own the professional cordless OPE market in North America and offer something to all those companies working in gas powered OPE-Free neighborhoods?  Put something like this together!  The Ego PPPS - Professional Portable Power Source.

How about making it even better, though...  instead of loading it up with 1.7kWh worth of batteries, how about cutting that down to 1kWh or so and adding an optional solar panel to top it up?  The unit itself would be smaller and easier to carry while providing enough power to recharge several Ego packs.  For those contractors who will be using the equipment heavily throughout the day, optional solar panels can keep it topped up and ready to charge.

Many residential solar panels are good for between 200-300W, so offering either a single or double panel solar kit (depending on usage and geographical location) would keep that power pack charging batteries all day long.

Another improvement would be to integrate the actual charger(s) right into the Power Source.  Two or Three charging slots integrated right into the unit would eliminate the need for the standard chargers (which are also not ruggedized for that type of outdoor use), and would be FAR more efficient than converting battery power up to 120V to power a charger that will need to convert back down to 56VDC.

Of course it would also need a couple 120V outputs as well as USB charging capability.

Consider also the marketing advantage it would give a lawn care company who can now claim they are truly solar powered!  :-)

I like the thought, but unfortunately I think that a 100W panel simply wouldn't do it. The 7.5 Ah batteries at 56 volts are 420 watt hours (0.42kwh). If you have full sun on 100w for 1 hour, you are only getting about 15 minutes of use out of your lawn mower (assuming a 60 minute run time on a 7.5 ah battery). You would have to have a single 7.5 ah battery idle for 4X the amount of time you would be using it. 

I'm thinking more of a Tesla Power Wall where you could continue to add batteries in series, as many as you wanted, take them out to use them, and put them back in to charge or serve as backup. Not that they ever would, but, if the batteries go bad, the modular nature would allow you to swap them out pretty easily rather than having to have a costly repair of the entire unit.

A little bit more than $200, but here is $250 for the 7.5 ah battery: https://www.grainger.com/product/38ZE09?cm_mmc=PPC:+Google+PLA&s_kwcid=AL!2966!3!50916698157!!!g...

As a solar and battery backup designer I also would very much like to see smart charging.  Currently the only way I can see to do this is with smart plugs, that turn off the charging circuit when the solar is less than the energy demanded by the house, and on when there is too much solar power to use.

But I would love to see an adaptation that could use functional EGO batteries, as a passive back up system like we can see with Goal Zero or Anker.  If we had a charging station with an outlet on it, we could use it as a resiliency adder. 

And if that charging station had communication capability, we could hook it in with a solar system to act as a grid resource.  A single 7.5A battery at 56V can power half a house (400W while a house uses 1000 W continuously on average).  So if a customer had a Lawn Mower and Snow Blower, and Chainsaw, and Weedwhacker, and back pack leaf blower, that would be enough to actively manage loads in a house.  

EGO, I love your tools, but most often they are just sitting in my garage.  I would love them to become even more useful every day!
