    So I modded my Prius to get a tap into the hybrid battery. This gives me 200-250VDC, which the meanwells are content to accept. (Most switch-mode power supplies are) Although it can source 21kW peak,...

    Since I last posted:
    The bike is mostly unchanged. I did have a successful test of the J1772 adapter on the first try. I have been riding as weather allows. I moved to Ephraim, UT, which is 65 miles...

    Cooked the ESP-120 somehow while soldering output wires on. Not sure what happened, but it gives me no output voltage now. Lame! All I did was solder onto the terminals, no idea how that...

    I've still been riding the bike when I have opportunity but that hasn't been much lately. I've been out of state for some travel and rarely need to go anywhere solo since I quit my day job about two...

    I rode the bike a 220mi round trip last month, it worked great. The RSPs are happy to max out a 20A 120v circuit. I also threw the DeltaQ in the backpack since charge time was my limiting factor and...

    The bike is essentially done. I've been riding it around for errands and I've opportunity charged a couple times- at a gas station, and at a coffee shop, which was neat. I still have a few need-to-do...

    If I needed to, I could connect the long charge lead and stuff it all under the tank lid and charge. Once I figure out what I'm going to do for...

    Progress today! The RSPs are mounting on the bike, an I could use them in a pinch. They've been internally ruggedized with some acrylic caulk (it's what I had around) on the vibration-prone...

    Thanks for the pointer, Joe. I still have the old CA 2.11 installed on the bike but the CA3 is just waiting to be installed. I did find the method to reset the amps to zero just now and did so....

    Indeed. I wish my bike was a top-tier frame rather than a shady Thai knockoff- that gives me as much anxiety as range does.

    I modified my second RSP-1000-48 for low-high operation. Firstly, I...

    Rode the GPR-S to work earlier this week and today. No issues- just charged it for 30 min with the prototype charger, pumped up the tires, and rode.

    I picked up a second RSP-1000-48, so now I can have compact charging, on-board. I just need to build it. It'll work great from a 240v source or 120v/20a outlet, but I need to figure out how to dial...

    What I’m curious about is the last 20% of energy into my pack with the fast charger, since it has no algorithm programming, it’s just CC/CV- dumps 24.5A into the pack until it reaches a voltage...

    I haven't observed the phenomenon myself, I've just heard it from both Joe and the Johnsavesenergy guy.

    Do you have any thoughts on my fast charger charge termination question above?

    Yes, 20.13 was what I noted on the clamp ammeter. That was with the pack voltage at 87.1v (it rose ~0.6v, I think, from resting voltage, according to the CA). That AC current might rise as the pack...
