    Problem with Victron 12v 30A DC-DC on a Peugeot Boxer with smart alternator

    The negative is off a cable going direct to chassis (not the starter battery terminal). As it’s a motorhome the D+ comes from the EBL. It‘s working fine. We‘ve connected positive to various places, piggy-backing on existing fuses and also directly from the unused 8mm bolt. Tried another cable...

    Problem with Victron 12v 30A DC-DC on a Peugeot Boxer with smart alternator

    We’ve revved the motor to around 2000RPM - no difference. We realise it could be that particular vehicle or a weak alternator, hence why we tried the 10A DC-DC (exact same result).

    Problem with Victron 12v 30A DC-DC on a Peugeot Boxer with smart alternator

    Not as low as that. It is dropping but not so much. We’ve connected a 2nd cable just in case the cable was too thin, connected to different bolt on + terminal, still same.

    Problem with Victron 12v 30A DC-DC on a Peugeot Boxer with smart alternator

    No, it's dipping down but not as low as that. It looks as if the voltage drop is over the 1.2m cable to the DC-DC, but 16mm should be more than ample and we've done loads of other installs using 16mm cable without problem.

    Problem with Victron 12v 30A DC-DC on a Peugeot Boxer with smart alternator

    Hoping someone can help here, perhaps having had the same issue with the same or similar vehicle. We installed a Victron 12v 30A DC-DC non-isolated charger into a motorhome built on a 2022 Peugeot Boxer with smart alternator. We’ve installed many DC-DC chargers, quite a few on vehicles with...

    Connect two JK BMS to Can Bus so inverter can control both

    Using the assistants you can control various aspects, such as when to charge batteries from the grid and the choice of using battery vs grid etc. But he’d rather control things from his inverter.

    Connect two JK BMS to Can Bus so inverter can control both

    Hi folks A request for info from someone, and I’m unsure of the answer as I’ve never tried it. He wants to control two batteries with JK BMS using the same Can Bus. He wants the inverter to control various things. I would have suggested a Multiplus but he wants to go a different route. Anyone...

    Juntek 200A smart shunt counts negative amp-hours after reaching 100%SOC

    We put the KG140F through it's paces in this review: On the whole I quite like the KG140F. I had both Victron and KG140F installed and over a week of touring I used them both quite extensively. Because we use quite a bit of power I like to know the real SOC at any one time. In this review I...

    $2948 for (32) (280aH)(New) LiFePO4

    Agree that’s the theory. Actual tests that we conducted show that the theory doesn’t hold water in this particular case. It’s a classic case of gut intuition (or theories) conflicting with the data. The data says that the smaller surface area isn’t an issue (probably because you can apply a...

    $2948 for (32) (280aH)(New) LiFePO4

    I did some stress tests on the welded studs and they came out tops, here is the thread: https://diysolarforum.com/threads/review-of-capacity-and-terminal-temperature-cells-from-shenzhen-luyuan-amy-wan.22371/

    Juntek 200A smart shunt counts negative amp-hours after reaching 100%SOC

    It’s pretty easy to re-program the shunt to connect to a different display. Easiest is to plug the new display into the shunt usb and the go to the ADR menu option.

    Juntek 200A smart shunt counts negative amp-hours after reaching 100%SOC

    That’s what I was hoping (in vain) for.

    Clawing back money for miss-sold "420ah" cells

    Except that the OP (that would be me) specifically asked the seller if there was a mistake. The seller made it very clear that ALL the cells tested out at 420ah. We asked for test results, we were assured that they would all be 420ah. Other people have experienced the same. How on earth can you...

    Clawing back money for miss-sold "420ah" cells

    We have another dispute that we have taken to our CC provider. It's for Juntek shunts (Juntek shunts) We lost the dispute on Alibaba arbitration, so hoping Barclays CC will refund us as we have a box of 20 shunts that are not fit for purpose.
