Re: [EVDL] 100 - 200 Ah LiFePO4 Cells in Europe, Where to buy?

The CALB CA series (gray cells) are the stiffest and usually test out to more than their rated capacity when new. From the little bit I've been able to glean the Winston and Sinopoly are basically the same as the yellow TS cells. There used to be an EVTV affiliate in Amsterdam but that affiliation

Just install a generator transfer switch. There are several UL listed options available. When the switch is on "generator" that part of the system is disconnected from the grid. Just hook up your PV/battery system to the generator side. On Tue, Dec 23, 2014 at 9:11 AM, Michael Ross via EV wrote:

So much misinformation people have. Li-batteries already last more than 2 years, they already charge in under 4 hours if the infrastructure can handle it, and why do I need a 5 minute recharge when my car is going to be parked for over 8 hours while I sleep? Don't get me wrong, this is a great disc

If this is a change then I would investigate. I have had my pack in for over 4 years and have not had the issue you and others have had and my pack isn't exactly closed to moisture and dust. I have 40 TS-LFP100AHA cells in a 2p20s arrangement. Because the BMS I used to use attached to the heads of
