    JBD Bluetooth

    FET locked can be reset by touching the slider button (yellow background) next to POWER off and on again. Usually resets it but when it's FET locked one of those slider buttons is usually highlighted in red, either charge or discharge side.

    Li Time 100ah on Ebay $255

    I watched a youtube video on the litime mini being frozen then discharged. Had pouch cells and compressed between 2 steel plates. Was interesting to see how the voltage increased as it defrosted.

    DC House on ebay 100ah $152

    Yeah I watched that too, look like rebranded eco worthy but the capacity test went to 7v but for the price I'd open up and swap out the bms as it should stop at 10v

    Exploding Delta Pros

    This is why I never buy something based on a "paid promotion" video on the tube or until they have been around a few years. These paid actors simply jump from product to product (usually the ones paying the best commission on sales) and I see them contradict themselves over and over again. Feel...

    DC House 12v 100ah $230 ($210)(11/22-$180)(ebay12/12$149)(ebay2/15$146)free shipping

    I watched one get tested and tore apart on YT but UK based. It wasn't the worst built battery i have seen personally but the BMS let the battery drain well below 10V at a 0.2 capacity test and in the UK ebay website i saw this code BUYBETTER25 which means it is 187GBP still way more than the US...

    Did i Damage My 12V 100A JBD BMS (SP04S034)?

    By the way, which BMS in the string failed The main positive battery from the 4 in series. The main negative and the other 2 batteries were unaffected. As I know the max amps I pulled couldn't be to blame, I wondered if it just didn't like 48V hence trying to educate myself a bit more about...

    Did i Damage My 12V 100A JBD BMS (SP04S034)?

    Yes I believe I did everything to the letter. Now my confusion is with how to determine if the Mosfets on a BMS suitable for series connection are only good for 24V set ups instead of a 48V system. It seems difficult to get any information on mosfet voltage types and limits. There are so many...

    Will this inverter be able to charge my batteries automatically when the price rate of electricity is low on Economy 7 tariff?

    To my knowledge that inverter won't be programmable for set charge times. Assuming your in the uk going by the links there are some inverters that are compatible with octopus energy, givenergy systems for example solis inverters can be set to charge at the cheap rates. The eco worthy will no...

    DIY battery or just go off the shelf?

    Battery prices are dropping which is great but when you consider a DIY build there are many additional costs such as tools, wires, bms, power supply for top balancing etc which soon add up and as such I'd say buy a pre built unit to meet your demands. Added bonus is a warranty if you buy from a...

    2024 YouTube Video Ideas

    The fact Will is looking for new ideas for content goes to show how over saturated the solar market has become. Every topic and use case has been well covered by Will and others on the Internet.

    Problem with JBD BMS Heat function on

    These bms heat functions will only work when they see a charge voltage and the other issue is if the charge circuit is off and the temperature drops the low temp side will also kick in and stop charging anyway. Ideally the bms should take or allow some voltage to go to heat pads only until...

    Server Rack LiFePO4 batteries. Where to find UK stock?

    I see the Fogstar are £1049.99, roamer are £1620.00 and wonder what difference justifies the big price difference,

    Server Rack LiFePO4 batteries. Where to find UK stock?

    Shame as I was looking at the Fogstar server rack for a project but there seems little info about them, build quality, comparison etc and have been looking at offering from voltacon and others.

    12V 100AH MINI or Group 24 with Low Temp protection? Bluetooth would be nice to have.

    I just watched a video on the tube where a LiTime Mini is tested and opened. Interesting thing was seeing how it performed when it had been frozen and it has pouch cells and only over temp protection.
