I thought I'd order a couple of little bits of wire to connect the cells to the Multiplus. 2 x 50mm2 tinned copper wire 5 metres long. I nearly fell of my seat at the prices.

Just suffered the video ;) Please DON’T use a cut of disc indoors, the mess will make you regret it later. And the cack handed way he used the hacksaw made me cringe. I would’t use an aluminium frame for batteries in a domestic installation, if something went wrong the consequences could be...

It’s a well known fact that paranoia goes hand in hand with a good engineer. I forgot about the little Chinese temperature controlled relay. I have one on my desk. Two of them in series failing open would be good. For good measure a bimetallic switch could be added to. A good idea about the...

Three jobs are required then David. 1. I need to connect mains to the multiplus in Betty. 2. Make a lash up with the BMS and lifepo4’s 3. Use Betty to discharge them and recharge. I’ll have to check my stock, but I think a Victron smart shunt will be on my next order David. A small fan heater...

Based on bits I’ve managed to retain, I think the cells I’ve purchased are “raw” cells with a capacity measured in a way similar to lead acid. So 280ah is really 200 and a bit in real useable terms. This is staying above 3 volts per cell and not charging much above 3.4 volt, avoiding a...

I had a look at a few of his videos this afternoon, but unsure about his conclusions about cell balancing.

I do wonder about low temperature charging of lithium's by the Solar and MPPT. Is the tiny amount of harvesting really going to harm them?

They don’t have to be new David, they have to be very new.

Does the Daly BMS have an independent temperature sensor or does it have its own internal sensor?

Sorry more boring pictures, it’s a slow progress and I’m fearful of having to destroy work because I forgot something. Just one more piece of aluminium to put in the remaining window, the previous window was reduced as well in length. The wardrobe will cover some of the window, so it was just as...

Chatting with my owner, Anita. The suggestion was made to house the new batteries in the base of the wardrobe. This could speed up installation as the underside locker needs some reinforcement and repairs. They would still roughly be in the same place, but above the floor rather than below it...

24 volt again lol

Before I went down the victron resistive shunt method of coulomb counting I purchased a couple of inductive counters and if they would have worked they would have been good. One thing was the inaccuracy of the voltage displayed, but then if you think of it as a number that equals the actual...

Yes these were from Basen, it is always a problem when purchasing knowing what will happen with your order. There are too many what I call "bedroom businesses" They take your money and hold no stock. We don't take deposits for parts that are yet to be made. If they don't want the part when...

They are here! Just typical, so much customer work on and so far behind with it means little time to play. Tracking their progress was rubbish, as they were supposed to be still on the boat yesterday. Next job I guess is to buy some crimps and a big crimping tool for them. Heat pads are...

Mine are just a couple of years old I think. The cut off for production was week 24 2021 I think.

It seems the smart blue chargers have to be rev.2 to be updated to smart networking. :(

If you watch some of the motorhome crash tests, the doors fold in without that bracing in place. I suspect the side impact protection would be compromised too. That said I'm sure you are not planning on crashing?

Posh people with new kit ;) My victron chargers don't have the option.

The original controller I had in Murky had a separate temperature controller, but it was close to a window and I had better results with the heaters built in sensor. This new controller that only works with the latest canbus heaters needs an extra sensor. In hindsight, I would have put the...
