They offer 4000 cycles at 100% Depth of Discharge (DOD), 6000 cycles at 80% DOD, and up to 15,000 cycles
To connect in series or parallel, batteries should meet the below conditions:
identical batteries with the same battery capacity (Ah) and BMS (A);
from the same brand (as lithium battery from different brands has their special BMS);
purchased in near time (within one month).
Because of the different BMS, it's not recommended to connect these 2 types of battery in series or parallel.
For versatile system configurations, you can connect multiple Dyness 12V 100Ah Trolling Motor LiFePO4 batteries.
You can expand your battery bank's voltage and capacity by connecting identical batteries:
Series: Connect up to four batteries in series to create a higher voltage system (e.g., 24V, 36V, or 48V).
Parallel: Connect up to four batteries in parallel to increase the total capacity (Ah) to 400Ah.
Series-Parallel: Build a larger bank of up to 16 batteries in a 4S4P configuration (4 in series and 4 in parallel) for maximum power and capacity.
⚠️ Critical Connection Requirements
To ensure safety, performance, and longevity, all batteries in a connected bank must meet these conditions:
Identical Model: Use the exact same battery model (e.g., Dyness 12V 100Ah Trolling Motor Bluetooth) with the same capacity (Ah) and BMS rating (A).
Same Brand: Never mix batteries from different brands. Each brand uses a unique Battery Management System (BMS) that is not compatible with others.
Recent Purchase: The batteries should be purchased close together, ideally within one month, to ensure they are from the same manufacturing batch for balanced performance.
Voltage Matched: Before connecting, ensure all batteries are fully charged and their voltages are balanced to within 0.1V of each other. This prevents large inrush currents that can damage the batteries.
As you are storing the battery for a long period of time, here are some suggestions for long-term storage for your reference.
1.Temperature: A temperature between 10°C to 35°C / 50°F to 95°F is ideal for long-term storage. Store in a fireproof container and away from children.
2. Capacity: For a longer-lasting product, it is best to store your battery at a 50% charge level and recharge every three months if it is not going to be used for a long time.
We always aim for make sure our customers love our products, but if you do need to return an order, we’re happy to help. Just email us directly and we’ll take you through the process.
If you want to return an item because of personal reasons (such as unsuitable size), we usually do not cover the cost of the return, but if the item has quality problems, please contact our customer service and we will solve the problem as soon as possible.
Shipment was quick, battery charged up within 36 hours to 14.2v. So far, the battery is doing what it should be. It is being used for a back up system wired to a 12v/120v inverter/charger. The assistance from Moka on the support staff, in reseasrching the proper battery for my needs was was greatly appreciated. So 4 stars for the battery, if it works when needed then 5, we will see. However, customer service gets 5 stars, it rare to find quality and professionalism in todays business world.

Purchased group 31 10AH battery to be used for my trolling motor. So far it has been perfect. I made the mistake of buying one that was a little large for the application but it did work out. During the process of installing I reached out to the Dyness team and they offered to exchange it which was very nice but I was able to make it work in the location I needed. Seems to be a great groups of people who stand. Evon’s their product.

Was so happy to get an equivalent battery for my sump pump. Old 7 year old AGM 120AH lead acid battery that weighs 80 lbs, would have cost $600 dollars for an exact replacement, is out. This battery weighs nothing and if I wanted to, i can use it with an inverter on the go or as backup power. I hope it lasts just as long or as longer. The Paperwork it came with is detailed with a storage baggie.

These batteries arrived on time and came pre-charged which was a nice touch. I ran into some issues early on wasn’t sure if it was the solar gear (turns out it was) or the batteries themselves. Their support team was super helpful and easy to deal with though. They walked me through fixes for the solar equipment and I didn’t have to hassle with the batteries at all. Highly recommend Dyness definitely buying from them again.

Great batteries. I tested the 100ah one and it actually came in slightly over 100ah, which is a nice touch. Also really appreciate that they arrived already charged—no waiting around to start using them. Right now I’ve got two set up in parallel, and they’re doing a solid job powering my whole living room. I’m charging them with a Victron 100/50 and 700w of solar, and it’s been smooth.
Their customer support is awesome too—they’ll help you work through any questions you have. Not a big deal, but I even love the graphics on the battery. Overall a great experience, and I’ll definitely be buying more.

I bought four batteries two months ago. They look great and are supper light weight. Low temp charging disconnect with a great low price. I think I'll recommend my friends to buy them.

The quality is great, and the shipping is fast.my wife took the delivery for me, and when I opened it up, I found everything I needed included. I’d say this brand is the best bang for your buck. The instructions are especially well written and easy to follow. Highly recommend!

These batteries are fantastic! I bought the three pack of 12.8 volt 100Ah to supply my greenhouse electrical needs, about 600 watts. Three days later the battery I'm using is still pumping out power and is still green! I'm waiting on the solar panels and I'm sure they will be more than sufficient. No more grid!
