NOTE

  • Please make sure to charge the battery immediately after discharging. We recommend limiting discharge to 85%-90% depth of discharge (DOD) to avoid the BMS protection system from disconnecting the battery
  • Please do not reverse the polarity of the battery pack to avoid the battery short-circuit
  • Do not dwell the battery in a full SOC for an extended time
  • Do not cycle below 10% – 15% SOC unless you really need to
  • Re-charge the battery when you did not use it for a long time (When < 50% SOC)

TIPS: Before use in parallel and series connection, make sure every LiFePO4 batteries are:

  • Full charge the batteries individually with a 12 Volt charger
  • Batteries start off with the same state-of-charge
  • Batteries form the same brand with the same BMS systems

12V 36AH LiFePO4 batteryFQA

1. Can this battery be charged with a lead-acid battery charger?

We recommend our customers to use a professional LiFePO4 battery charger to recharge it. A lead-acid charger is unable to fully charge a LiFePO4 battery.

2. Can LiFePO4 batteries be connected in parallel or in series?

Yes, please make sure to fully charge the batteries and all batteries are at same voltage level before using them in series or parallel. We do not recommend mixing series and parallel. Please be noted that there should not exceed 3 batteries when connected in series or parallel.

3. What should I do if the battery cannot be charged and cannot be used?

Our battery BMS has multi-protections to ensure safety: Short-circuit Protection, Over-current Protection, Overload Protection, Over-voltage Protection, Over-charge Protection and Over-discharge Protection. Once a protection triggered, the battery will be unusable temporarily.

Three Circumstances to Reactivate the Battery:

 

  • Normally, the BMS will automatically restart the battery after the abnormality is eliminated (about 30 minutes).
  • If the battery still can’t operate after 30 minutes, please try to recharge it at 14.6V to reactivate it.
  • If the normal charger can’t reactivate the battery, please check the battery voltage, the battery won’t be recognized by normal charger if its voltage is under 8V, now please use a 14.6V lifepo4 charger which support 0V charging mode then it will work.

  1. BJRB

    This is a fantastic battery. I use it for Ham Radio portable operations. Very light weight and can easily be transported. I use it with ICOM 7300 and run 50 watts all day. Easy to keep charged with a solar panel. Looking to purchase a second battery to run in parallel for 100 watts.

  2. Bob M.

    Works great 8 plus hours on a single charge.

  3. Levi GALevi GA

    I’ve purchased 2 Lachy 12V-18Ah batteries for my Mobility Scooter. So far I am very satisfied since I’ve installed into my Mobility scooter, and continuously driving 5 days indoors and outdoor of my scooter the batteries indicator still show in full. So I won’t buy any more of AGM Sealed Lead-acids battery, they are worst battery type, don’t less than a year the won’t hold charging!! I’m fully recommend to others buy the Lithium type like this products. Light weight and can holding the voltage after charged! Able used more than 5 days never drop much of the voltages! Love It!

  4. LTLT

    The first time I used a Smart Car Battery Charger to charge the battery but failed. I thought it was a battery problem because though my friend also met this problem when using this charger, but the problem was solved after he replaced a new battery. I contacted the seller and sent them the link of the charger. The seller asked me some details patiently and told me that this charger is for lead-acid batteries, can not charge lifepo4 batteries, and as this charger’s reviewers said, it may damage the lithium battery.Then the seller sent me a new battery, and recommend me to use a professional lifepo4 battery charger to charge this battery. I purchased a new professional lifepo4 battery charger then and successfully fully charged the first battery. So far so good and I sent back the new battery to the seller.Good product, good customer service.

    I used this to for my ammo can project. It fit perfectly inside of my ammo can shoved to one corner and I still had plenty of room on 3 sides for my wires and chargers/inverter etc. I have no way of testing the true capacity of the battery but I can charge phones and tablets for a family of 4 off grid at the ranch for a 4 day weekend no problem.

  6. Scott V.

    Seem well built, very stable charge and discharge. Doing what they are supposed to do ! Solar power and lithium charge controller.

  7. Gary G

    I could build a segway with this, but I am not sure what I’d use this for. Seems useful for backup phone charging when on a trip.

  8. A

    I’m using this for a solar light set up in the backyard. It runs 6W led lights all night.

  9. M D Welch M D Welch

    The media could not be loaded.

     I was looking for an option for a lithium battery to power the Livescope on my boat and didn’t want to pay double just for a catchy name. This has proven to be a great choice, 9-10 hours on the water and it’s still going… definitely outlasts me. Money well spent in my opinion. A+

  10. Amazon Customer

    Much lighter than lead acid and works great for my trolling motor
