Hi Actually they do have Bluetooth. I have ordered a 100A 4S separate port. Cost US$72 including shipping to Australia. The only reason they are not marketing it right now is that they do not have an app ready for it. However there is a "mini program" in WeChat that can be used to monitor and...

Hi - where would you get an MPP for $300? They are about $1200 for a decent one! Regards

Hi I did read the thread after posting here. Rookie mistake - should have read the threads first I guess. I think you were talking to the JK shop on AliExpress. I was talking to the JKBMS factory. They have confirmed that - with the addition of this parallel module - you can wire them in...

Hi - The MPP already has an auto switch over function built in. It will switch over to mains if the battery gets below a set point. You can also set it up to bypass to grid if the load is too great. There is a great write up on this on Wills blog. BTW his conclusion is that they are a great bit...

Hi That is for the Solar Charger Controller only - I was referring to the MPPSolar off grid system here.

Hi Have not changed them at all, but then I have not been testing g at high amps. Still waiting for my 100a capacity tester then will run one cycle at as high as I can. I don’t think there will be any issues though. Regards

Hi I See they now have a 200amp constant charge / discharge - https://www.lithiumbatterypcb.com/product/3s-12-6v-4s-16-8v-or-4s-14-6v-lifepo4-battery-bms-with-120a-to-200a-constant-discharge-current-for-12v-converter-power-ups/?attribute_specification-selection=4S+Lifepo4+200A Regards

Hi Read this blog post here. Might help a bit. https://www.mobile-solarpower.com/all-in-one-solar-power-packages1.html

Hi You can buy directly from MPPSolar. They sell on a number of platforms and they are shipped directly from the factory in Taiwan.

Hi Found these on AliBaba - look identical and are available. They will sell single units as well Regards

Hi The problem here (as in lots of posts) is posting just to bash a product without attempting to solve the problem. You have also jumped on the band wagon - along with a lot of other posters - without actually showing any knowledge of the product itself. Has it been setup correctly ( I don’t...

Hi Just a suggestion but do a video of the capacity testing and the internal resistance testing as AliBaba seem to place far more trust in a video than pictures. I just had a whole box %50 pieces) of LiFePO4 18650 replaced because they were under capacity. There was much baulking until I posted...

Hi Grounding a system to the chassis is common terminology. No where would you ever expect to equate grounding in a vehicle to that of earth grounding, as in earth spike. To quote the manual “Connect to Ground / Chassis” and in that reply I was, indeed, referring to the manual. Regards

Hi I had a few of these BMS on test and I found that one stopped working. Blue light was on but no connection. The app did not even recognise it. I unplugged the Bluetooth module and plugged in a spare one and all was ok. I plugged the failed one into another BMS and it worked fine. Had some...

Hi Everybody I am going down the road of building some LiFePO4 battery packs for my off road camper. The space I have to install is pretty limited so will not be easily accessible. For this reason I am looking for a Bluetooth enabled BMS (preferably Daly as that is the recommended one here) Does...

Hi These might be a better price point. However I think you will find using the cylindrical cells more cost effective. The BLS Store seems to be one of the top notch stores as well , in my view http://s.aliexpress.com/meqUrU3E regards

As a As a starter battery yes agree, but a a 2nd battery for everything lead acid does not last. Not made for long term cycling

Hmmmm OK.

Hi If you measured the voltage you would see it decrease as the battery charged. Old type alternators maintain a constant voltage irrespective of battery charge. It should also state it in the manual. Regards

The Chargery? If so has a switch for internal / external power.

G'Day Fred. Going down a similiar path but replacing AGM with LiFePO4. Regarding the BMS - if you look at the Daly BMS they have high current seperate input / output models. This link is for a 48V 200A seperate input / output for LiFePO4 cells. Hope this helps...

What are you buying / trying to buy?

Hi Savage. I have a similiar challenge where my well is about 15m deep and I pump into a header tank about 3 metres off the ground. I built a small solar system (1.2kw solar panel / 6kw storage and 3kw off grid inverter) This lasts about 4 hours of full time pumping. I have now installed a 24V...

Hi They also have a guaranteed shipping time so if it is not sent within that time you automatically get your money back. There is also a glitch in the system though because the 152aH LiFePO4s I ordered arrived before AliExpress had them as shipped. Regards

Hi Horsefly You are correct, apologies. When I first set up a battery (some years ago) I noticed the name was not written to the BMS. Regards Richard

Hi Have you looked at the Daly BMS? They have very high capacity amperage (charge is always lower than discharge) This is a 16S 48V 200A Seperate Port https://www.aliexpress.com/item/32888385718.html?spm=2114.12010612.8148356.2.772037fe3BaQPd Regards

The challenge is in finding a LTO compatible BMS that does 6S. I have only found 5S. You would need to edit the charge volts as well because a fully charged LTO in 6S is 15.6v and LTO in 5S is 13v. This is generally enough for most 12v systems though.

From which dealer and what brand. I am looking at YinLong at the moment.

Hi I have recently found a new app on the Apple store that works great with the JBD BMS and has a (in my view) much cleaner display. Has all the functionality of the Xiaoxiang with regard to Read / Write just much cleaner. The app is called (very imaginatively) Smart BMS Utility and costs just...
