Why Choose Siekon?
  • This battery cannot be used as an engine starting battery for automobiles. That's due to the limitation of using it in a low temperature environment and the fact that the discharge current may not meet the CCA standard for starter batteries.

  • It doesn't require a special battery charger. For better-charging results, here are some suggestions:

    The recommended charge current is 20A

    The recommended charge voltage is 14V

    The recommended max charge voltage is 14.6V

  • This 12V 100Ah battery is BCI group 31 size. Item dimension: 12.95*6.77*8.43inch.

  • Because of the long transportation and storage time, the battery may self-discharge, it is recommended that the user charge a charge, and then measure.

  • It is recommended to use a charger dedicated to lithium batteries and do not exceed the rated power for a long time.If it cannot be charged, disconnect the charger, disconnect the load, and let it stand for five minutes before charging.

These batteries do quite well considering the price range. Good capacity. Good output. So far so good. I just bought two more.

Two of these connected to a 600w Bluetti power station ran the refrigerator in my RV for seven full days.

So far this baterry is great. Seems to be at least 100 AH as advertised. Time will tell if it is reliable and durable. will update if it works well for at least a couple of years.

A great product and delivery was faster than I expected. It’s a little heavier than I expected but again it’s a large capacity product

Replaced lead acid batteries in ergo txt. Much peppier with better range.Small changes required to battery box required. I cut three pieces of 2x6 to raise battery to a height that it cleared the old box. Battery sits nicely and is strapped into place

The battery arrived in good shape, in spite of the somewhat basic packaging and my first action was to check the battery voltage as shipped...this measured 13.17V. I hooked the battery to my lab power supply and charged overnight at a 10A rate at a charging voltage of 14.4V. By late the next morning, charge current had dropped to a few mA, so I unhooked at left it to settle out to a resting voltage of around 13.35V.Having a battery load tester at my disposal, this morning I connected my battery load/capacity test module, adjusted for a 10A load and after 10 hours and 12 minutes, the battery had delivered 102+ Ah and 1251Wh of energy. Battery voltage measured at the battery terminals at that time was 11.79V, though the load tester was showing only 11.1V due to voltage drop in the 12ga connection cables between the battery and the test module. This was consistent with the voltage drop I saw at the start of the test, so in reality the energy delivered was 6% greater than what the test module recorded due to losses in the cabling. Needless to say, I'm pleased with the result.The battery itself seems well made and was supplied with two sets of bolts for connections to the flush battery terminals. The case seems reasonably sturdy, though not up to the level of a BattleBorn battery that I've had for 7 years and is still going strong after heavy and varied use. I haven't yet weighed the battery, but it's quite a bit lighter than the 100Ah BB that I have...will weigh both soon.A great price and time will tell if this battery delivers the same trouble-free performance I've received from the BB that cost 4X as much 7 years ago.This battery will replace an older SLA battery that I've been using to power a number of strings of outdoor LED lights. Load is about 4A from dusk to dawn every day to power a small inverter which powers the light strings. Battery is recharged via a 300 watt panel and cheap 20A MPPT controller, so I have plenty of overhead to accommodate a run of cloudy days and still keep the battery topped off.

Well this battery is so far so good Make sure to wake up your batteries before going out on your first camping trip If you don't know what that is make sure to look it up different manufacturers are different but most say to cycle the battery at least five times all the way charged all the way dead at least five times make sure you're using the correct style of charger as well. After doing that you will have much less issues all lithium batteries need to be "woken up"
