These are WAY bigger and bulkier than my other CATL 271aH prismatic cell. I bought them thinking they would have been easier to move around since it's only 100aH. They are bigger then the 271Ah cell. At least they are lot sturdier and look like I can throw them off a bridge and still be able to...

2015 using the serial number

this lower the cost of the winston cheap cell I've bought so it a nice thing ;) at the pricepoint I bought them it's basically almost throwaway cell when empty. Now time to find VERY cheap smart BMS (or even non-smart) ? Thanks !!

between 3.29 and 3.38

Hi, just bought a bunch of used CALB CA100. On the sticker it say "Lithium ion battery cell" and everywhere else it say LFP4 battery. Which one it is ? ?? Since the lot came with a bunch of LYP4 Winston WB-LYP100 and WB-LYP300 cells I bought them but I hate dealing with ion battery, especially...

BMS 1 version 32.0 manufacture date 2021-1-14 BMS 2 version 32.0 manufacture date 2021-1-14 Both ordered and received at the same time from aliexpress Ordered two bluetooth smart shunt because I find the remaining capacity fluctuating too much when drawing load or charging

I saw a version on endless sphere but did not try it

mine is doing the same thing. I guessed it have to do with interference while charging. Mine is a aliexpress version

my aliexpress version of this bms is doing almost the same thing but almost only when I balance them. I then lose the ability to connect reliably. Also, I something change a setting in params setting and it do the same thing but usually it's when I reach the balance point. I think it just create...

Wow look nice. Do you have all of your 8 cells in there?

is this a dewalt tool chest ? I plan on doing the same but I was hesitating 8 cells in one or 2 toolbox with 4 cells each

Hi, anyone have tried the CATL 280Ah lifepo4 prismatic ? Can't find any review and what to look out for? Thanks !

Did you find anything worth ordering with less or free shipping to Canada ?? Thanks :)

I ended ordering overkill 120A BMS with Bluetooth and uart rs485. Now when looking for part I've found aluminum booster cable (1 gauge) for fews small connection to the outside pole. Any downside when using this kind of cable with ring connector (metal or even copper since I know I shouldn't mix...

Wow thanks I'll go with that one.. Any downside of taking the uart rs485 instead of just uart? Thanks!

Thanks for the head up, I'll buy these instead. Any way to send me the direct link since aliexpress search feature is a mess? ?

The true specifications are a bit hard to find... I can live with 50A charging because I'll probably charge them both at the same thing (100A total) BTW I'm still looking so if you have a cheaper and better idea I'm interested ? In the end the total price for a kickass power station will be...

Probably Daly bms with Bluetooth without screen 100A (around 100$ cad, maybe 75-80$ USD each)

I plan on buying the same 100 or 150A. Actually I'll have two identical powerbank and when I'll need more power I'll parallel them

One last question guys.. Any downside of using two separate battery with their own bms in parallel. Ex2x150A bms for 300Ah output? Will these two bms play nice with each other in parallel?

Yeah actually I'll use two bms with one battery each, but charged by only one power source for the two battery/bms assembly

Wow guys you are amazing !! (almost spent few $$$ for a 400-500A BMS) I live in Canada so it should not be that far from US typical specs Can I parallel my solar charge controller or generator on TWO BMS (so it would charge 2 smaller 12v 280a battery) ? also about my inverter, I did not check...

ahah yeah I've oversized my usage a bit (it should be around 1500watts) So I should size my BMS on what would be my amp usage instead of my whole battery A ? Meaning I should be able to get away with a 100A BMS and this will charge my battery to 580A even if is a 100A BMS but only be longer to...

Yup I'm wondering too if I could use something like a 8s bms on a 4 cells battery

Actually I've calculated few time and end up with around 1500-2000watts. The inverter I'll use is the one already in my RV so it's hard to know. I don't know much about lithium cell so I don't know if I take two small 100Ah Bms and charge them in parallel I'll end up only charging them to 100A...

Need help to size a BMS for either 2 x 12v 280Ah or 1 x 12v 560Ah I plan on charging it with 4 x 100watts 12v solar panels everyday and top it with a generator when there is no sun or too much power use. I plan to use these battery in my travel trailer or a small portable battery bank (in a...

Thanks for that Dzl!!

just a quick question about the same topic guys, If I'm building a 280Ah 12v battery, I should aim for 300-350A BMS ? Also, would theses addons would be useful in my build : 50w heating pad with thermostat low temp cutoff switch 30A inline fuse breaker cigarette lighter output x 2 USB output x 4...
