Hi lovely crew, I have just bought myself a JBD to replace the pain that is the DALY situation. Finally I'm getting more feedback from my battery setup. I want to make sure I allocate the settings correctly. I can already observe that the total battery capacity is too high. What do I change...

Hey all, It seems my batteries have not been charged by the solar panels. I am getting the below experience, where the voltage starts climbing every 30 seconds or so, jumping rapidly from 12.4 to 14 and then back down again. The triangle exclamation point pops up too at 13V or so. Does anyone...

What is going on with my Daly BMS? My battery keeps switching off randomly, I'm unsure if my charge controller is even working with the lithium charge any more, and I can't access ANY settings, via bluetooth, or via PC over USB. I am going freaking insane. My suspicion is that the battery is not...

Hey all. Nearing completion of the install for my van I just want some feedback about this connection I have from my main battery busbar to the 50A fuse holder for my charge controller. Im using a small 8awg wire as you can see in the photos (small red wire top right) I wanted to ideally have...

Hi there! I have some left over copper that I want to use as a bus connecting my positive from my 12V battery and negative from the BMS to distribute to my 2000W inverter and 40A charge controller. Im wondering if it is acceptable to support these copper bars by screwing them into the wood...

I had to create 3x busbars with a different thickness to the ones that came with my EVE lifepo4 cells. The main reason was to successfully connect one pair of the parallel cells in series successfully as illustrated in the photos. The new busbars are 1/8" thick, unsure of the size of the...

Hey all, I'm connecting 8 lithium 3.2V 272aH cells in the below configuration. I am just double checking that this arrangement is accurate. Im just about to cut my own busbars so wanted to make sure this is accurate before connecting them together.

Ive been holding off buying pv cable as a lot of the ones on ebay dont describe whether they are pure copper. Yesterday I messaged two sellers and they both said they only sell tinnes. what conductor doyou have in your pv solar cables?

Batteries in series Voltage of benchtop at 14.6V Current all the way to the right completely randomly the benchtop display jumps to something like 13.6V and 9ish amps

hi all! last night I successfully used my lifepo4 battery pack for 3 hours while busking in the street. I powered a valve amp and several guitar pedals (even scored 10 bucks ! ) i want to charge the batteries up as they were at 60% soc on the app. There isnt much information on charging in...

Where the heck can I find these crimpers in Australia? Work Horse Crimpers. Searched absolutely everywhere and they just do not exist!! For wire 22 -6AWG

4S, 12V 272aH Individual cells 3.23V LifePo4 Daly BMS 4S 12V 100A powertech 12VDc pure sine inverter Set it all up last night finally and applied some load. I can charge my battery fine, but when I plug in my laptop charger, the multimeter climbs to roughly 10A and the power turns off at the...

Hey guys! Very excited to finally wire all my batteries up. Using a Daly "Smart" BMS I have 4 cells wires in series @ 280aH or so. Cell 1 negative to the positive after the fuse reads 14V DC However, on the BMS P- to positive of the fuse, I am reading 10.28VDC Any ideas why this is? I've only...

Looking... for a 210A fuse as per Will's book. Using a 2000W inverter in a 12V system So.... I can't find one anywhere. Closest is 200A Top result on google is a thread here saying that they cant find a 210A fuse

Hi there, I have a 500W inverter I am planning to power with 280aH array of 4 cells and a 100A BMS. Doing the basic calculation as follows 500W inverter max load/12V battery = 41 Amps. I need a wire thick enough to carry 41A Based on Will's advice in his book, I based my max load on the...

I'm unsure if this is explained very clearly in the resources which has made it quite challenging . When purchasing the BMS, I based it upon the an assumption of the likely max amount of current I would draw at any one time. My understanding is that the Amps of the BMS chosen should corresponds...

Hi there, I purchased two BMS from Shenzhen Basen Technology Co., Ltd. One is a Lifepo4 4S 12V 100A One is a Lifepo4 4S 12V 200A They look pretty similar to the Daly BMS designs. The BMS doesn't have any identifiers aside from 'Smart BMS' and a product number R05A-FK16. I've plugged one in...

How do I appropiately size a lug for a wire that is tiny? e.g. the input cables for the BMS. The ring would of course need to fit over the battery terminals also. Is there another method of doing this? I thought of even just soldering the wires directly to the battery terminals but realize that...

I'm having trouble getting my batteries past the 3.35V mark. 4 x 3.23V 272aH LoFePo4 Cells in parallel. Today I changed my method to the incremental top balance (@3.4, then put psu to 3.5, then to 3.6 etc.) after waiting maybe 4-6 days setting the benchtop powersupply to 3.6V without the...
