Battery LiFePO4 Motorcycle 12v Lithium Phosphate Iron Battery Built-in BMS Board - High Performance - Replaces YTX20L-BS 20L-BS ETX20L CYTX20L-BS GTX20L-BS For ATV UTV snowmobile KP20L-BS

Installed in a 2011 Harley Heritage Classic softail. Physical dimensions are identical to stock battery, so no spacers needed. Fired up fine the very first try - my engine is tougher to start than stock because it is bored out and has high compression cams. Ran load test at 2k rpm and it stayed around 14 volts which is normal. Built in meter is nice to have. This battery weighed 3.5 lbs on my bathroom scales, whereas the old AGM weighed 15 lbs on my bathroom scale. Huge weight difference, plus the new battery has more CCA, and does not lose charge - so no need to hook it up to a battery maintainer unless you intend to leave the bike parked for six or more months. No liquid chemicals inside, so no leak hazard. Other than being slightly more expensive than an AGM, I see no drawbacks to this lithium ion battery. My order arrived from China, but weeks earlier than stated. Doubled boxed with foam padding, so it arrived with no damage. 2 year replacement warranty is comforting. English instructions were adequate, but inaccurately state that it is a lithium “iron” battery, and have several other translation quirks. (Update: my engineer friend says that the chemistry of lithium ion batteries includes iron (Fe) as a key component, so technically it is accurate to call it a lithium "iron" battery.) I’ll try to update this review after a reasonable period of time to test battery endurance.

This is a great battery.It has only one problem that I have found.My Indian Chieftain regulator will not read the battery's voltage causing the regulator to hunt and change charge voltage about every second.When it charged on the hi side my headlight and spots would flash about every few seconds. At the flash, my heated grips, seat, jacket and gloves would also flash.The grips and seat, would turn themselves off. The jacket and gloves would not turn off and this battery burned them up.I put my Autozone 310 CCA battery back in and it appears the damage was limited to the Hotwire gloves and jacket.The stator and regulator are steady, the lights don't flash and hopefully the damage is limited.If you have a newer bike with CANBUS, avoid this battery at all costs, it will destroy your gear and bike.

This 20 AH LiFePO4 battery is quite small and light for its capacity. I am using it for my amateur radio go-kit to supply power for my radios when in the field or other activity. It fits easily in a small carrying case for portable use.

Battery Has No Life At All Only Lasted Four Months In My Harley Had To Charge All The Time Afraid To Go Riding Because Maybe It Would Start Maybe It Wouldnt Warranty Sucks After Three Months Still No Battery And No Warranty

So put this is my Chopper. AGM and Lead get shaken and don't last. A 1 yr old AGM would no longer crank bike. Put this in and it cranks stronger than ever before. CCA way better than OEM and way lighter. Very happy initially for the price and cranking speed. Only time will tell for durability.

Waited awhile to receive this from China, but man what a deal! They included a free mini charger too!! In fires up my 2006 Victory Vegas 8-ball right away!!

So far so good in the snowmobile!

Demasiado tiempo, mas de un mes y el.articulo no llega.

This is a review of the 20Ah model.This battery is surprisingly light. It came with a 1 amp 14.6 volt charger, however it's a European plug so will be useless for me here in Canada. I already have a 14.6v charger to use for this anyway.I tested the capacity 3 times, and all 3 were under half the rated capacity of 20 Amp hours.1 - Using a hall effect sensor: 9.81Ah.... roughly 100 watt load (~8 amps), lasted just over 1 hour2 - Using a shunt: 9.2Ah.. same 100 watt load (~8 amps), lasted just over an hour.3 - Using an inline watt/ammeter: 9.35 Ah... this time 13watt load (~1amp), lasted just over 9 hours.All 3 tests ran the battery from full down to 10.4 volts, the level at which the inverter shut down.Granted I'm not using this in a motorcycle, however I would expect to get close to the rated capacity of 20Ah when paying for a 20Ah LiFePO4 battery.

I'm going to try contacting the company but i am only getting about 111Wh usable capacity before it barely puts out any watts. I have run this this test 4 times with an inline ammeter charging a power station at around 72W and i always get around the same result, 111Wh or 8.7Ah. The shipping was fast, the product packaging, case and terminals all look good but the most important part, the battery inside, is not so good. UPDATE, tried to reach seller and discuss a solution or fix for this lack of capacity but seller decided to stop responding after a reasonable offer was put forth.Update, the company would not issue a satisfactory refund for the lack of advertised capacity. Would not buy again.

DO NOT BUY THIS BATTERY,!! I wish I would have read through the reviews better. I agree with everyone here that says this battery is junk! It has no capacity whatsoever. I have installed 4 of them into an electric go kart and it runs for less time than my old lead acid. I guess I should have listened when people warned me about Chinese batteries. Another $800 down the drain...

Review of the 20Ah version.This battery only delivers 10 Ah. Very disappointed.Vendor explained that this is a starter battery NOT a storage battery. IE, it provides very high current for short periods of time. It will not fair well as a lower current long discharge cycle battery, which is what I was looking for. (A long term radio transceiver being used at a remote site)

Superbe service with this compagnie the battery work flawlessly on my quad just not let it outside in winter but in summer no problème at allThanks again for your good productWish to make business with you again10/10
