AH ok I understand now. Guess I just had to get someone to spell it out for me. So if one set of cells has a slightly lower capacity, significant current COULD flow through the balance lead to the other set.

I was just cold emailed from a company called SodiumWatt which seems to be a trademark of Shenzhen Han hailong science and Technology Co., Ltd. After some conversation they are going to send me 3 sample batteries in a standard 150*99*99 case. 12V 15AH. Mainly we are interested in the cold...

I am currently reading and learning about this technology as we speak. It seems great for our application. Do you know any other companies I can cross shop with? We have made many decent business connections from cold emails. Metal works, CNC services, wire harness building, etc. Often its hard...

@Ange Rod Welcome! If you have not already, contact Orion, they have very good customer service. Also read the wiring guide, it is also good. I am not entirely sure what your questions is though. If you want to share a connection with the charger and load then do so. Remove relay 2 and share...

Has anyone done any tests on JUST the back of these panels? how much does the backside really generate compared to the front?

Also interested when more people get these batteries. for Perpetual, no the BMS is not easily adjusted. In an good setup the BMS should never hit OV or UV, your downstream devices should be cutting out before that. If you want more control of the BMS i would suggest building your own battery...

The manufacture did get back to me with a pretty basic datasheet. CANBUS is optional and 6 weeks lead time. I also wanted to confirm that it will accept both 110 and 220VAC inputs for various different locations which it does. @HRTKD For a marine environment If the charger is only grounded on...

I think you are over estimating how much power you need for propulsion. Not a bad thing, but I suggest some thinking on this. Using OceanVolts calculator https://oceanvolt.com/configurator/#power They only recommend a 6 or 8kW motor, and cruising at 5knots requires 2kW. Those old diesel motors...

I think you need to show us your whole circuit. What is the application here. You want to share the connection with the charger and the load. But you don't want to power your load while charging...why? I can't think of any application where this would be a requirement. The Charge Power Source...

I know there is plenty of smart people here. Tell me why this is a poor design. https://www.halcium.com/ From what I see: Pros: - no exposed blades means its safe around boat sails. Hoist and forget it. Cons: - Fixed sized makes PITA to store. - Efficiency will be less than traditional systems.

Recently got some advertising for this new local company selling LiFePo4 batteries. The prices look almost too cheap. Community thoughts? Local supplier would be amazing for Western Canadians...

I have a question about these BMS. If I want to run 16S2P (100AH each cell) Do I need 2 BMS units or 1 and tie all the parallel cells together? Does each bank get its own current sensor or can they share?

WELL. i searched for ablithium and nothing came up. guess i could have searched a little harder. Mods can kill this thread.

Looking to create a 2x2 power bank with Telsa 24V modules. 2 series by 2 parallel. Each module is 74p6s so that gives me a total of 148p12s. 48V system will be powering a 20kW (peak) BLDC motor and a variety of accessories. I want to use these cells for their compact and weight savings compared...

https://www.electriccarpartscompany.com/48v-35a-hw-lithium-battery-charger Anyone know where i can get a datasheet for this charger? I would like to get information from the CANBUS and if it can be configured on the fly.

Hi folks, Firstly, I am aware that no advertising is allowed on this site. I will refrain from posting any links or spam to our proposed product. We don't have a company or a product at this time. Being a shill is not my intent, Scarily, i am looking for you opinions to make a great product...

Any longer term results from these Gotion cells?

https://graphenergy.ca/products/ I am not able to disclose the capacity but its significantly more than typical super caps. Any idea what chemistry would be inside?
