I posted this info in another thread but it was on the end of a long thread - so may well be missed by many. Reposting the info here so others get to see this info. I believe this small Hatz diesel genset to be very different to every other small genset I have seen...

Anyone seen these in the wild yet? A nice way of reducing the number of interconnects and thus overall resistance when trying to get a big Ah setup

Can EVE 304 or 314 amp/hr cells be installed laying on thier side? If so, any particular orientation that one should use? Or is it not such a great idea to put these cells on thier sides ?

Given the latest data suggests that charging up to 3.4v max can result in more cycles from the batteries (life span) is it feasible to use 17 3.2v cells in series for a 48vnom setup using a Victron Inverter ? Victron can accept up to 66v. 17 x 3.4v = 57.8v, 18 x 3.4v = 61.2v. If we charge up to...

Considering voltages to use for a Lynch pancake motor setup. The motor can be run at 48vnom, 72vnom or 96vnom. For various reasons 72vnom looks attractive for my needs but I also need to install a 48vnom battery. That is, in this setup scenario I would run with a 72vnom battery and a 48vnom...

Have read read many posts here re paralleling cells. Not seen anything really in depth about it though. I get that a group of cells that are paralleled all have the same voltage and that you lose visibility on each individual cell. What I am trying to figure out is what is the practical limit...

I am new to mppt's - never used one before so coming to terms with how they work. The inverter I am looking at gives these spec's; The panels I am interested give these spec's; and the **COLDEST** temps at my location (I am in a hot location but it gets a bit chilly at night - 62F/16C -...

I am trying to figure out how to charge a battery bank in the bow of a sail boat. The charge sources are at the stern of the boat (as I guess most charging sources would be in a sail boat). The battery bank up front would be around 30-40kWh at 48vnom. The DC cabling should support up to 200...

Do the cells heat up very much when charging or discharging? Is there any advantage to the cells if the temperatures of the cells is reduced while operating? If so, how much cooling would be needed and how would you get this cooling to the cells?

How many amps do the bussbars connecting cells together, carry? In other words what amperage do we need to make sure the bussbar connectors can carry? in a 48vnom setup with 16 cells are all the cells outputting close to each others output? or is cell 1 putting out more amps then say cell 12...

I am interested in measuring cells so that I can batch cells together for making 48vnom batteries - batteries will be in parallel connected to a bussbar. I am looking at importing a large number of cells so that I can test them all and keep the best cells and sell the rest. I need to "Match...

As I have not actually built out my batteries yet I am still getting a grip on every aspect that goes into building a *SAFE* battery. What I am wondering about at the moment is how to build out the battery with some way of attaching balancing charger leads to a cell while its still in the pack...

I wish to put PV on my sail boat. My Boat/inverter system is 48v (Victron). Because space is very limited on a sail boat I can only manage a total of 4 panels with possibly 2 extra down each side mounted vertically - so if did that it would be 8 panels in total - (but not sure if that is a good...

I am offered EVE 304Ah cells in local warehouse for the lower prices we are seeing these days. The issue is the cells are between 1 -2 years old (ie, manufactured up to 2 years ago). If I want fresh cells I have to order from China - thats a huge logistical nightmare for me (long story but I...

I dont have any cells on hand to measure the height of the 280-320 class blue alu cells - does anyone have an accurate idea of the height above the top of the cell?

I am a little confused - but my knowledge of motor controllers is almost zero, so not surprising. I am interested in fitting a PMG to the flywheel of a diesel engine. The PMG uses a motor controller to control the charging of LFP batteries. I really dont understand how a motor controller is...

Been reading as many Bussbar threads here as possible. I have read about Copper and Aluminum buss bars and the pros and cons of Al vs Cu. Thing is, even if one were to use Cu buss bar, it still should be plated with Tin, or interestingly, silver (Ag). There are good reasons for plating, and...

Like many I am waiting for the bigger LFP cells to come on the market. Not sure when we will ever see them though. Came across this. https://www.infolink-group.com/energy-article/energy-storage-topic-intersolar-europe-2024-overview-energy-storage-industry

Just been hit with a dilemma. Was set to go with LiFePO4 system but have found that the country I am in, has this year (2022) introduced a 10% duty rate and 16% VAT rate on Lithium batteries. Lead acid batteries are duty free and zero rated for VAT (meaning no VAT is charged on them). I was...

Looking for EV cells and wondering what brands are favored at this time? I see Hithum mentioned here and there but know little of them. Are they a reasonable EV quality cell?

The Victron MPII 5kVA has a 70 amp charger on board - how does this equate to power draw from the AC side? By this I mean how many kW/Amps is the MPII pulling from the AC side to provide 70 amps of DC charging ?

I have been in communication with EVE for supply of EV cells and he gave me the following prices. Not sure that MB30 are EV cells though? I was told the EVE 304aH or the Catl 306aH are the EV cells. Still this pricing is useful to have.
