DCHOUSE 12V 50Ah Lithium LiFePO4 Battery, Built-in BMS, 10 Year Life, More Than 3000 Cycles, Perfect for Boat, Marine, Trolling Motor, Camping, Solar/Wind Power, Motorhome, Fish Finder

After some decent long term use this battery has proven to be reliable and has maintained its capacity. Shoved in an outside shed it has coped very well to power some 12v lights and a small cctv camera. Excellent value has been derived from this quality product.

These are great and light batteries - replaced lead acid batteries to power bilge pump. Great long life can be carried easily with no danger from spillage etc. I had a small issue with one of the three batteries i had and the customer care was exemplary! Highly recommend.

Got the 12V/12Ah/154Wh version quickly, safely packaged, and all is as it should be. Not too large or heavy; it can be taken on a walk. It was pre-charged at perhaps 50% and works well with a transceiver that draws 6 Amps max, ca 450mA when receiving only. I recharged the battery with a bench power supply that supports CV&CC mode as required. DISCLAIMER: It is strongly discouraged to use anything else but a dedicated battery charger with appropriate settings to charge Lithium batteries. If improperly handled these batteries can get damaged or destroyed, and in the worst case they can explode into a difficult to extinguish massive fire. The battery specs claim C=12A and a standard charging current of 6A at 14.2-14.6V. To start on the safe side I set the power supply to 14.2V/2A or C/6. At 2A and 13-14V the battery gets charged at 26-28W which predicts a charging time of around 6h given a capacity of 154Wh. The picture shows a charging diagram (upper left). All looks as expected. There are plenty similar diagrams available on the internet for LiFePo batteries. The battery did not get warm (22C room temperature), but the power supply, rated 300W, switched the fan on every 5 minutes for 5-10 seconds. Nothing to worry about. The upper right plot shows a discharge curve when powering the receiver at an estimated 450-550mA, which is what the receiver draws when powered by the bench power supply (which displays the current). 500mA would be C/24 implying a total discharge time of 24hours at that load. The battery was probably only charged to about 95% and gets discharged to about 15%, a difference of 80%, in a little more than 1400 minutes = 24 hours in total. That might suggest an up to 20% higher capacity than the specs claim, but much of this discrepancy is likely due to an overestimated discharge current. The lower left plot is for a second charge of the battery at 14.6V / 6A = C/2 from around 15% to close to 100% - the internal safety circuits (BMS) switched the charging off at the end. The charging time is a little short of 2 hours as expected. The lower right plot is a second discharge curve using the same receiver as before. The initial sharp drop is common when discharging LiFePo batteries the first five or so percent down from 100% to 95%; this time the battery discharged in a bit more than 24 hours down to a level between 15 and 20%. Whereas it is difficult to determine the precise charging level from the measured voltages in the flat regions, it is easy to detect the much sharper transitions from steep to flat in the charge and discharge curves. These can be used to restrict charge/discharge ranges to ~80% only, which is often claimed to prolong life of LiFePo batteries. However, every few times these batteries must be charged full in order to trigger the internal balancing processes. Somebody mentioned in a different review their battery gave up after 6 charges. That may have been a dud or the BMS somehow got triggered and the battery is just sleeping now. Some battery chargers have a wake-up mode. For me, so far everything seems fine. For outdoor activities and carrying the battery in a backpack, the terminals of the battery are too exposed - I'll have to build some caps to avoid accidental shortcuts. The connectors can also be mixed up easily - adding 10 to 20 Amp diodes in the charging and power cables will make sense to avoid accidental wrong polarities.

Bought this battery to power my lister liberty clippers. The old battery pack has had it and it’s very expensive to replace, this battery was a 12v 4500mah. I did quite bit of research and opted for this 12v 6Ah and I’m not disappointed, the clippers run perfectly on it. The battery came well packaged and fits in the bag with my clippers and blades perfectly.

Small and light and very handy. It seems to offer the advertised capacity of 6Ah too. I left it running a circuit and forgot about it and so it completely discharged down to 2V. I would have expected the BMC to shut off the output before getting this low but obviously it didn't. This made it difficult to start the battery charging again as the 3A charger I was using (see my review of this) could not see the battery due to the low voltage.

I bought this battery to use with my HF transceiver. It work really well and seems good quality. The price is good if you can get it with a discount. Recommended.

I got some of these to replace the two heavy Lead/Gel batteries in the battery pack that came with our electric wheelchair. They are fantastic, wonderfully light (in comparison) and seemingly much more powerful. I had to get a charger suitable for LiFePO4 rather than use my original one and adapt a charging cable for the power pack. Not too challenging.

I like it that it is small and light and seems to hold its charge well. All good so far. Loads of uses.

Bra pris och snabb leverans. Beskrivningen stämmer med produkten, bluetooth ansluter enkelt. Mycket nöjd så här långt. Rekommenderas!

Piccola batteria usata per alimentazione faretto all'esterno si può usare con un pannello solare o sennò la ricarichi con un caricabatterie,dura parecchio la carica io la carico ogni 10 giorni .ottimo prodotto

Muy bien, pequena y efficiente.

Bra, lätt och snabbt levererat.

Ottima batteria agli ioni di litio. Arrivata col 75% di carica, con una tensione di batteria di 13 volt. Ottima la capacità di 6 Ah che permette un utilizzo anche intensivo. Molto apprezzato il peso della batteria di soli 750 gr.
