As an aside, while installing these I noticed my SOKs, which are a year old, are showing some rusting of the outer case. These are not directy exposed to the elements but in a un-air conditioned space and so exposed to humidity in our gulf south location. I will be treating this with Rustoluem...

This "sale" did not exist at the time of my writing, but at the current time you might be correct. I believe the discount only applies to one battery so if you order to you still only get $60 off total. As an update, and for some further information. I finally did receive the batteries, quicker...

Thanks everyone. Before this writing I was under the impression that an LFP specific charger was necessary and use of anything else would ruin my batteries or cause them to blow up or something. Normally my LFP batteries are installed in an RV and charged via my Aims pure sine 3kw...

Thanks Mike. I could not see anything in the owner manual about "conditioning". FYI it is a " VIKING4Amp Fully Automatic Microprocessor-Controlled Battery Charger/Maintainer" so I am guessing it is 3 step ending in trickle or maintenance charge. It came from Harbor Freight. I use it mainly for...

So if the charge charges at say 13.5 or 13.6v and 4A it should charge the battery until full and then the battery BMS, which has over charge protection, should cut off charging when "full", regardless of the output of the charger?

I have two new LiFePO4 12v 100A batteries arriving tomorrow. I am expecting them to come in at 50-60% SOC. I will not have an opertunity to put them into service until sometime next month however I would like to fully charge them and then discharge once or twice to make sure they will provide...

After starting this post I broke down and bought a 2 pack of TWV- 100 AHr 12v for $524.27 all in, taxes and delivery, via Amazon. It shipped from California and should be delivered tomorrow or Saturday. I will post a follow once I receive them and get to test them. At this price range, I am...

I broak down and ordered 2- TWV minis using the link above. At the price I could not pass it up so we will see if they are any good. Bought them on Amazon. Shipped within 24 hours from California. Free shipping for ground delivery. (1-2 weeks to me.)

CS1234 thanks for posting these links. Yes, these are the battery types I am speaking off. At these prices they are competivtive with many wet cell deep cycle batteries.

I recent months Chinese brands like LiTime and other similar ones (may be all made by the same manufacturer) have introduces "mini" small form factor plug and play 12V 100 Ah batteries. These are generally about 20% more expensive than traditional P&P units of the same capacity but are about...

In designing a system I realized I am going to need wither a single large MPPT charge controller or several smaller ones. I pricing these out I can currently get several small MPPT with a combined greater amperage rating for less money than one large one from the same manufacturer. What would be...

I am creating a battery bank of six - 100 amp 12v batteries in parallel and am contemplating using a copper, steel or aluminum bar as a busbar to connect all the batteries together, one negative and one positive. This is mainly because the bank is in a mobile environment and I want to add...

Here is a follow up question (seeking clarification of this subject): As I understand it, batteries in parallel give amperage to the demand in equal parts. As as example, if four 12v 100 Ah batteries are connected in parallel it is the equivalent to One 400 amp 12 battery, so it there is an...

Correct. That is what I get for writing on the forum at 1:40 in the morning. I meant PARALLEL to maintain 12vdc

I have a small LiFePO4 battery bank made up of 100 Ah 12V batteries with 1C discharge rate and 100 Amp BMS. I was offered some additional batteries that are the same except some have 100 Amp BMS and others have 200 Amp BMS. Does the difference in the rating effect how the batteries charge and...
