Update for July 12

The battery issue has a new proposed solution. Instead of shipping used batteries via freight, the idea is to source new lead acid batteries from a supplier in Winnipeg and have them shipped within the city. The mechanical details of the batteries can be worked out, and the battery boxes will be simple and easy to deal with. Removing the heavy batteries from the shipment makes the electric motor module MUCH easier to deal with. The carrier requires no special instructions for handling ... it's definitely a win-win situation.

I'd like to use in a lithium pack, but it is expensive and requires a different charger, which is expensive ... a new lead-acid pack is reasonable for a prototype. A less expensive pack and a bullet-proof charger make the mistakes less costly ... remember, this is a proto-type!

I'll be investigating which batteries are available in Winnipeg, for a good price. Of course, they need to be safe to put into a moving vehicle. And it would be nice if they did not need to be watered. Maintenance is ongoing and does take time. The batteries need to be more accessible to water them, or a watering system must be installed - another cost. I`ll be searching for a good option over the next week or so
