| Budget conversion. Seems to be progressing well. Website : www.evbmw.com 10/02/10 : Fitted the charger and have done a first test drive at 48v. Charger working well but needs a few tweaks. Looking at using a kats 1500w 120v block heater for the cabin heat. Much neater solution. Commenced fab work on rear battery racks. May be going to 120v with ten Odyssey PC2150s Complete revisit on the adapter plate / coupler. Now using a solid coupler and much neater adapter plate. Runs soooo much better the the stupid jaw coupler i had been using. Well worth the effort. 02/06/10 : Had major motor problems. Removed , advanced and com turn later all is well. Now running at 120v.
