RE pack works great. But the price is not really a deal maker. So only one pack was sold 2 years ago and no problems were reported.

Perhaps a kit without batteries could be offered at a lot lower price that would interest a few more buyers?

I'd like to have the DC-DC converter and controls. I don't need their battery pack.

Dropbox maintenance in progress. If any of my links aren't working after November 17, please PM me and let me know which one isn't working.

Thanks.

"The little key fob remote is interesting: you pull out a small antenna, and can control remote charging timers, or start/stop manual charging, or cool, heat or defrost the car while it's hooked up to its charger. "

Here is a excerpt from a review:

Another simple solution Mitsubishi uses with the i is its bizarre remote key fob. This non-Internet-connected device can communicate wirelessly with the vehicle (if within range) to pre-heat or pre-cool the vehicle, as well as set the charging process. We think the fob is too big and does too little – and carrying another digital piece of plastic is annoying – but company spokesman Maurice Durand reminds AutoblogGreen that Mitsubishi is really dealing with a car that's three years old at this point, and the fob was the simplest solution without adding cost. We hope that a smart-phone solution will be coming at some point.

I guess we will have to get a hold of one it before we can do much.

Any Ideas?



We know that the i batteries life are best served by not always fully charging. So I am using a Titan Controls Day Night Photocontroller NYX1 to charge either at night or during the day. I would prefer a remote hack connected power controller that monitored total charge and stopped charge... Another benefit is saved energy from not cell balancing every day.

Yes I was thinking the DC-DC could be used to connect PV's on the roof?

300 watts on the roof, and another 300 on a hitch-mounted unit containing a couple kWh's of liFePO4. Perfect for those <10 mile days.

I did have some discussion with them and they are willing to sell without cells. However, they are using 3.7v cells and my candidates are LFP, ~3.2v. Using LFP with their kit is more risk and trouble than I want to go to. I asked them for a quote, exported to USA, but I didn't get a reply.

The system sounds just like the Enginer kit, in that it trickle "charges" while driving. In the Enginer system, the DCDC output is connected directly to the pack battery before the vehicle current detecting loop, so the vehicle was still able to do coulomb counting etc...

The LFP would requires a different BMS setting.
