Building a battery for my friend. I have a K-B2A8S20P BMS. It won't come to life. I have verified on the harness all voltages are correct. Gone over the connection order and it just won't come to life. There's full, Top Balanced, voltage entering the unit but it's not coming out. I've built...
I'm curious as to why all the BMS I see on the market have such small gauge power cabling? Seems they should be larger. I was just looking at the stats of a 120 amp BMS which claims 500 amp limit of discharge current. Seems this much current would liquify the small output cables.
Can anybody tell me if the settings in a Tri-Metric will be retained when swapping a battery bank. I was thinking, if not Id patch in a 9 volt battery to it to maintain settings.
I'm basically bench testing a 12 volt 305 ah. LiFePo4 battery build I'm doing for a friend for his RV. I have the battery connected to an inverter for load and a Xantrex C-60 for charging, It appears to start out working fine but then CC goes open circuit soon after connecting. This open...
So I just received 16 eve 230 ah. cells from Jenny at Doucan. They arrived in perfect condition. What great packaging. All 16 cells measure 3.293 volts right out of the box.
My question is, Is it absolutely necessary to top balance them being they are so perfectly balanced now? I have to ask...
Got a new phone and trying to get the BMS app back on my phone. No matter where I look and try to get that app by name. I am being shown lots of related apps but the one I'm trying to get will NOT show up.
Is anybody else having this problem?
Wondering if I can get it direct without going to...
So, when parallel wiring batteries it is beneficial to make your load and charging connections at diagonal corners of the battery. I have a friend who will be mounting 4, 12 volt solar panels on a trailer. They will be parallel wired. The panels have J boxes on the back so they will be wired +...
I have a friend who want's to replace her, end of life, FLA batteries with a drop in LFP battery. I'm wondering if she needs to replace her Xantrex C-40 charge controller with a (more adjustable) MPPT controller. The C series controllers have fully adjustable voltage settings but as far as I...
