Great info! I've heard about Greay info, exactly what I was looking for! Unfortunately I haven't read a much about Heltec active balancers so I'm unclear how they'd be used to intially balance the cells. Are you suggesting that I connect the cells together, then wire up the BMS and also wire...

I am an engineer with a lot of experience with large 48V and 53V DC power plants. I am normally a DIY type of person. I do my own appliance repairs and I do the maintenance on my own vehicles. I've restored 5 "handy-man special" homes, inluding upgrading thier electrical panels. I also have...

I've yet to find any of the warantees mention any grace period about free shipping due to defects. The only grace period I've seen mentioned is for returns. Most give you up to 30 days to return unwanted items, but they almost always include a restocking fee. Typically the warranty includes...

I know from a cost perspective that it's cheaper to put together your own LiFePO4 battery than buy one ready made, but I'm wonering which is more reliable? Assuming that I purchase Grade a cells and good quality BMS. I've looked at Battle Born, SOK, LiTime, Lion Energy and others. All of...

Hmmmm... My comment was directed at the fact the proposed ban was for health reason and not for environmental global warming issues....that's it, that's the extent of it. I also said that I didn't want to enter into a great debate and yet here we are. I'll believe the ban when I see it passed...

Yeah..,. I have read all of these "news Flashes" but there is no mention of any such ban on the NY State web site....none that I can find.

I totally agree with your logic, but one step at a time. I estimated my worst case daily electrical requirement to be about 200 AHs and that would be with the heat running. About half of the load going to the Furrion all DC refrigerator. My end goal is to have a 2 batteries so we can camp off...

I would like to put together a 12V 4-cell lithium (LiFePO4) battery together for my travel trailer and I need a few recommendations and advice. First, is was thinking of purchasing the Grade A EVE cells (280 ah to 304 ah) from a site like 18650batterystore.com or DocanPower.com as I heard that...

I went over to jkbms.com and I can't find any reference to this BMS. I searched the page and come up with nothing. Is that an old BMS? I also noticed that none of their BMSs work with less than 8 cells. Am I misreading it?

Which JK BMS would you recommend? There are quite a few.

I was deffinetly planning to use a BMS, I haven't 100% decided on which, but I was leaning heavy towards the Overkill unit that Will Prowse recommends (Overkill Solar 12v 4S 120A BMS w/ Low temp Charging Protection). Is there a better one out there? I'm only planning on installing at max a...

I own an Travel Trailer and need to upgrade the battery in it. The cheapo lead acid battery is no longer cutting it. So I've been researching a lot about lithium batteries and I am very interested in building my own using LiFePO4 3.2v cells. Can batteries be put together without using a power...

I did not realize the limitations of the ElectroDucas system....good info. As for an inverter, we'd only be powering a flat screen TV, a DVD player, laptop charger and not much more, so we don't need much. Having said that I was thinking about using a 1000 or maybe even a 1500 watt inverter...

I'm in the beginning stages of planning or figuring out the best way to add solar capabilities and lithium batteries to our Travel Trailer, but I am confused about a few things. First, I haven't decided between staying with 12v or shifting to a 24v system. If I can locate the cells close...

I looked at the ElectroDacus , Batrium, or Tiny BMS web sites and was impressed. The ElectroDacus SBMS0 and DSSR20 modules might be exactly what I'm looking for! ...thanks!!

Please keep us posted

I agree on- solar panels, I only meant that I'm planning on installing at least a total of 400 -500 watts worth of panels. I have not picked out the panels just yet. I'm starting with the battery and I'm having enough trouble deciding between a 12v or 24v system. Once i decide that ill tackle...

New-bee here... I have a couple questions. Are you planning to use an inverter? If so, what size? If I'm looking to do something similar in my travel trailer, then I wont need the Orion-Tr Smart DC-DC charger will I? It looks like you are using it to charge up the engine start batteries...

Do I have the sizing correct? Meaning the BMS needs to be able to handle the max DC amperage drain at any given point?

I'm planning upon adding solar power to my Travel Trailer in the next year of so and I'd like do it in stages. The plan right now includes at least 200 ah battery of power (at 12V), four 100-150 Watt solar panels, a new converter for lithium cells, MPPT solar controller and a 2000 watt pure...
