Features
- Bluetooth Function: Compared with the traditional battery monitor, CHINS Bluetooth lithium battery has added Bluetooth function and obtain various data (SOC) of the lithium iron phosphate battery. Customers can connect to the battery through the mobile phone APP, and read the battery voltage, current and other important information at any time. Wireless connection range: within 5-10 meters from the battery.
- Heating Function: Only when Smart battery starts to charge, the heating function inside the battery can be turned on. When the ambient temperature is lower than 32F (0C), the charging current will only supply power to the heating film inside the battery. When the internal temperature of the battery reaches 50F (10C), BMS will immediately turn off the heating function, all the charging current charges the battery. The charging current of the low temperature heating battery is at least 10A.
- Lithium Iron Technology: CHINS Bluetooth lithium ion battery have exceptional longevity since they manufacturing by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power, letting you use the battery more freely. Our batteries are more cost effective, so when factoring time and cost into your purchase, our lithium ion battery banks come out ahead every time. It can support fast charging and solar panel charging.
- Capacity Expansion: CHINS LiFePO4 battery can be connected in parallels and in series for larger capacity and voltage. Max connection in series: Up to 4 identical batteries for up to 48V connecting in series. Connection in parallels: it can connect multiple batteries, suggest no more than 4pcs in parallel. Allow to be extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 1120Ah) and higher voltage (24V, 36V, 48V). Other installation methods: 4S2P, 2S2P, 3S2P, etc.
- Built-In BMS & Convenience & Maintenance Free: CHINS Bluetooth LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in high temp cut off prevents charging over 122 F (50 C). Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults. Brand: CHINS, Size: 20.47*9.44*8.58 inches, Color: Black, Orange.
- Automatic Voltage Equalization Function: CHINS 12.8V 280AH Bluetooth LiFePO4 battery is made of A-grade cells, and its cycle times can reach 6000-8000 times. The BMS of this product includes an automatic voltage equalization function, which can automatically equalize the voltage of each cell inside the battery. This BMS includes a Low Temperature Cut-off Function.

You MUST understand the following when designing your solar power system. Power is measured in watts. Volts times amps equals watts. 12 volts times 10 amps equals 120 watts. 120 volts times 10 amps equals 1,200 watts. I thought amps were amps, so I designed my system thinking I could run my 10 amp (1,200 watt) microwave for 40 hours with 400 amp hours of battery storage. Wrong. 1,200 watts at 120 volts is 10 amps, but 1,200 watts at 12 volts is 100 amps of continuous power draw from the battery. My system turned out have 1/10th as much power as I thought it would have, but I didn't know that. I have been dealing with power issues since I started living in my van 4 months ago. Every time I ran the microwave for for more than two minutes the batteries would shut themselves off then come back on a few seconds later. It turns out the 200ah 100 amp BMS (Battery Management System) batteries I bought couldn't handle the power draw. I had to replace them with 200ah PLUS batteries with the 200 amp BMS, which allows for 200 amps of continuous power draw. It took me forever to figure out what the problem was. These guys went way out of their way to help me on numerous occasions, including paying for shipping AND packing when returning a battery that turned out to have nothing wrong with it. I bought the batteries after seeing a YouTube video where a guy cut one open and was impressed with the quality construction. The batteries work great and other people I know with Chins batteries have never had any issues with them. The prices are better than most. What really sets this company apart though is the customer service, which is the best I have ever encountered. I have been repeatedly impressed by their responsiveness to my technical questions as I tried to discover what was causing my power problems. So yeah, I highly recommend Chins batteries. UPDATE: July 2023 -- It turned out that all my power problems did not involve the batteries shutting down at all. The power was cut by a circuit breaker which would reset itself after a few seconds. I had no idea self-resetting circuit breakers even existed and assumed that since the lever on the breaker hadn't flipped open the breaker had not tripped. I replaced the breaker anyway just to eliminate the possibility it could be part of the problem, which still persisted. Something to know about nearly all the circuit breakers sold on Amazon and elsewhere: They trip at much lower current draws than they are rated for. My 150 amp breaker was tripping at 100 amps. I replaced it with a 300 amp breaker and that solved the problem that had been defeating me for 9 months.

Using for my fish finder. Love the lightweight at 5lbs and small size. Works exactly as I hoped. One hand to carry it around. Charges quickly. Longevity TBD but so far so good.

These batteries are absolutely amazing… I cannot recommend them enough! I bought five in total and could’ve gotten away with three because of how long they last. One of the batteries was dying very quickly and when I talked to customer service we realized that my expensive NOCO GENIUS charger was the issue (not correcting voltage or something). I bought one of their $30 chargers and it resolved the problem. So I also highly recommend the chins $30 charger(s)!

This is a great deep cycle LiPo100ah. I use it for car audio. 3k rms. There is virtually no voltage drop. The voltage rebounds immediately. Harder, deeper bass as well as louder highs and mids. Resting voltage is 13.4V. The Shipping was very quick. Quicker than stated. Affordable, great value, I highly recommend for carcaudio, solar,RV, off grid.

I like that I was able to get it out of the rain before it got too wet. I won't know more until I open the box; meanwhile three stars will do. More later. Out of the box, it measured 13.16vdc on my Fluke. That is a good sign that there is no internal problems. More later.

The AGM battery in my dump trailer went belly-up. The attributes of a lithium battery, more specifically LiFePo, made perfect sense for the work of a dump trailer. With that in mind, I went shopping for a reputable 100Ah LiFePo battery. CHINS had a great price and solid reviews, so I made the investment and have zero regrets. What I gained from the swap from AGM to the CHINS LiFePo: 1) I get 8-10 dumps (maybe more) from a fully charged battery instead of 4 - extends the work day, if needed, makes me more productive 2) Half the weight (made install much easier) 3) Battery can be run all the way to 0% without worry of harming it (try not to go below 20% though - refer to next point) 4) Up to 5,000 charging cycles if I don’t run the battery down below 20% - an AGM battery *might*, maybe last three years or so realistically; the CHINS LiFePo could last 10 or more years! 5) The CHINS battery has its own battery management system (BMS), so I don’t have to worry about overcharging or damage to the battery if it’s too hot or too cold 6) CHINS included some nice terminal posts which made installation easier With the pricing of AGM versus LiFePo batteries running neck and neck, the only real “con” is the need to swap out the charging system due to the increased voltage required for lithium. A 5amp system (I wouldn’t go any less) will work just fine for a 100Ah battery. I found a good one for under $100 (an NOCO) and have been thoroughly pleased with the results. If you have the option, buy the CHINS battery. It’s a great option for the value.

Replaced my RV lead-acid batteries with these. Have good power, and dont appear to get hot when charging. NOTE: Have to have a charger that will do LiFe batteries, or the batteries will get ruined...
