yep but FYI- " We do not recommend connecting batteries of different capacities for use together. I am sorry to say that we do not offer a warranty for battery damage caused by connecting batteries of different capacities together." Sophia

Check this out. I found a used 230ah Lipo4 battery being sold directly from Redodo and they're telling me to not wire it with any other 12-volt batteries. My understanding is the BMS will do its job regardless (not that we want to build a bank "relying solely on said BMS" but it still should be...

is this considered "an eco" BMS? - its $140...

good points - thx. The load is just a 12vot fridge/freezer (50watts) and a 1500 watt inverter to run a dorm fridge, wifi router, 1 22" tv, 1 computer and some fans.

Anyone ever work Backwards from The Charging Tools to the Solar to the MPPT to buying a Battery >? In an RV Setup here - I have a brand new AC charging system that will trickle to max out at 50amps I have an MPPT Solar Charge Controler/MPPT that maxes out at 40 amp EPEVER Tracer (100v max). I...

updated - voltage is good - amps/watts are low - see pics System is: -4 6volt 235/ah batteries (series-parallel) -4 panels (2 are can solar / 2 are trin) both are close to 250 watts and 32 volts with 8.9amps optimal (they are used) -90' of 12-2 Outdoor wire / 1st i ran 1 string and got great...

Here is 1st video showing the entire system - (most of it). 2nd vid will cover full daylight testing -

12v since i have an older system / smaller system but most is being replaced but 2 solar panels on the RV - dont know what they are...

Since i have a system im adding too I'm thinking its better to stick with 12 volts... However, reading more - i see it's not suggested to tie more than 6 Lipo4 batteries together in parallel...? Considering weight, battery area, and its outside (will build a custom HDPE box to hold them/sealed...

Follow up Question Common Port vs Seperate Port? Also AssUming since i am buying 120 ah Cells - i need an 120a BMS...

forgot to mention "Cells" not batteries above - looking at the aluminum (blue) cells on Aliexpress - So i need a BMS of 8s - if i'm running the 400 ah example above Or a 4s BMS with only 4 "cells" at 200ah each.. :) Thanks!

Nice -why did you choose such a small Amp Hour Battery Setup? -price? -size? Did that affect your BMS choice, Solar Charge Controler and also Convert Size?

Hello Cany anyone chime in here on the (short answer:) for a BMS Setup... -Does it matter that i have 100 amp hr batteries vs. 200 amp hr batteries? -The Numbers on the BMS stand for how many batteries the BMS can handle correct? (4s - means 4 "terminals/4 batteries) - right? I haven't seen...

i keep reading about the Structural Worry about these blue aluminum cells - for mobile use -is this really an issue? i once drove my class C from inside Sebring Raceway over their bridge, thru dirt, grass, gravel and uneven concrete over 1hr home leaving a bottle of water 80% filled on my...
