I am looking for a submergable twist/thumb throttle. It will only be submerged max 3ft. Does anyone have any ideas about this?

I must admit, I still don't fully understand how the nuances of the BMS board works. Maybe by messing around with some of the suggestions given, I will connect all the dots and get it. One main question...Can I draw on the HCX-D131 board and charge through the board at the same time? And if...

Just to clarify....The BMS is balancing anytime the battery curcuit is closed, whether charging or discharging, but at a very slow pace, so only small corrects can be made when charging with 10A because at 176mA, it takes a long time to even curve the slightest imbalances. If this is correct...

Got it...files were too big

Side note: I used to get email notifications when somone replied to my posts...That did not happen this time. I will check my settings. I am also trying to attach pictures of the battery pack in the "upload attachment section". They are jpegs, but it gives the error message "invalid file" I...

My battery is 90% built and by the end of the weekend I should be ready to start balancing. If I am going to use the HCX-D131 balance board, what is better, to charge first or discharge first? I was going to use a few light bulbs to discharge.....Maybe a better question should be, now that the...

I would like to query the group about building a 24s1p @ 32aH Lithium-Ion "Kokam Style" battery pack with foil tab technology. I have searched google a little and found very little information...maybe my searches were not worded correctly. My questions will start with technical questions about...

I inquired about adjusting and he said that it was factory set.

I am working on buying a battery charger for this lithium-ion pack. I am looking at a 10amp charger configured for Lithium-ion. CC/CV 5% of CC cut-off. They are asking about the option of 100.8V @ 4.2V/cell or a 99.6 @ 4.15V/cell. The charger is from evassemble. I do not know what the best...

I need 24. How many do you have up for grabs?

I would like to buy these cells and use them in a 6.25C draw application and 0.625C charge. Does anyone have test reports using these batteries in this range?

In my investigations, an Italian contact has brought to my attention that he is using Lithium-Ion batteries from a Chinese source with good success. The batteries are 32aH cells with a 10C cont. rating. the cells are 820 grams each and cost $32 USD each. For my 24 cell configuration that is...

What is the skinny on the Anderson SB-350 as a connector for my 101V and 200-250 amp current draw? Is this Bussman fuse the best option for me? http://electricmotorsport.com/ev-parts/fuses-holders-2/anl-style-fuses/ann300-cnn300-very-fast-acting-limiter-fuse-300-amp.html

Is the Anderson SB-350 not upto the job? I will take the 1C advise and resize my charger. If you buy a more powerful charger, does the BMS have an adjustment to control rate of charge if the BMS was just used to charge and not discharge? I have not fully committed to which way I will set up...

I am looking at an Elcon 8000W HF charger configured to charging Lithium-ion batteries. Please correct my logic.... At 24s5p LiPo, charging upto 4.2V/cell would be 100.8V. 8000/100.8V=79.36a. The D-131 BMS can handle 80a cont. That would be 16 amp/p and a charge rate of 3.2C. Until someone...
