36V 100Ah LiFePO4 Lithium Battery Built-in 200A BMS & 15000 Cycles,3840W Motor Support,High Energy Density Golf Cart Battery,RV,Home Energy Storage,Off-grid Applications

I purchased this Dumfume LiFePO4 battery pack and I’m very impressed with the performance. The real capacity is outstanding and the energy delivery is stable. The runtime is excellent, especially for solar systems, since it stores enough energy to last through the night with no issues. Another great feature is the built-in BMS that protects against overcharge and deep discharge, giving me peace of mind. They also run very cool even under heavy loads, which shows their efficiency. With over 15,000 cycles, these are clearly built to last for many years. Overall, an excellent choice if you need reliability and high power for solar setups, backup power, or heavy-use projects.

They work exactly how they should. I ended up buying two 300 amp and two 314 amp. I used them every day from 100% to 0%. Ships fast. Planning to buy more all of my batteries arrived between 40%-45% SOC.

Received battery and needed a few clarifications, seller responded fast with the info I needed. Just got battery online and it charged to the expected max. As stated, I just got it inline so can't comment further than that at this time, at this time it is working perfectly

My 2nd purchase . Bigger capacity than server rack batteries and I dont need the Bluetooth or communication ports. 15k wh of power!

I bought this battery on Februaru 24 2026 based on good reviews only and it had 4 star ratings,,so i felt ok buying it In May..June and July just after 3 month my 12.8 100AH battery lasts only two hours on 100 watts fan at night when electricity goes out Now,, people might think it is a bad battery and that make and model no good.. I thought same battery in April 2026 but 150 AH Connected both in series to achiwve 25.6 volts So when my inverter quit after two hours on both Batteries ..my 100AH battery shows voltage of 10.3 volts But the 150AH battery shows 13.2 volts on average And does not drop below 13 volts Both batteries same make and same voltage 12.8 I do not understand how a Load of 100 watts can drain battery in two hours flat I do not want to conclude it is a bad purchase.the same make battery 159AH is working just fine I want to wait and see if customer support can shed light on that matter

Bought 6 of them, use it as a 24v system on my boat. solar charges everyday, last shorepower or generator run were 3 months ago. Just brilliant....

Excellent batteries.....I use Dumfume 100ah batteries in a 48v setup on my solar setup to run mini split air-conditioners.

Working great! even as i choose the lowest price for LiFePO4 batteries, i'm pleasantly surprised.

Alles Top!

Recueil en parfaite condition. Fonctionne a merveille. Le prix est vraiment bon.

j'ai un gros problème avec une de mes batteries ! j'en ai 4 en série les 3 première semble fonctionné parfaitement mais pour un raison inconnue la 4éme arrivé a 13.83 en charge monte d'un coup a plus de 17v................. j'ai déplacer la batterie dans la série ! elle était en 4éme position je l'ai placer en 3éme position pensant a un problème au niveau du câblage mais le problème et toujours centré sur la même batterie........... du coup mon onduleur coupe le charge car j'atteins les 58.4v hors mes 3 autres batteries sont a 13.4 ! mes batteries était parfaitement équilibré avant de les câble en série a savoir 13.16 pour les 4 j'ai contacté Dumfume j'attend leur réponse et je changerai ma note une fois le problème résolu.

En 6 meses de uso, ha fallado dos veces. Esta última vez, no logro que recargue. Considero que no es un buen producto. Una batería de litio de las características que describe, no debería haber fallado

This battery works well, though there's a couple of things to point out. The case is plastic (as described) and has no tie-down bolt holes like the metal cases have. This means that you have to design some form of battery hold-down. Also, unlike a more expensive conversion I did on another cart, this battery does not have its own on-off switch so it is permanently on and self discharging between uses. It would be easy enough to fit an on-off switch to it. Otherwise this battery is brilliant for its price and certainly does the job of providing a cheap conversion.
