Very Good Battery. Well worth the cost. Now that I have a couple of months of use, I can honestly say: You will find this is an impressive battery if your experience has been only with Lead-Acid batteries as mine has been. This battery seems to retain its charge well when left “on shelf”. It has amazing high current output over lead acids, specifically 10 amp drain for 30 minutes w/o significant voltage drop (considering it’s size I’m impressed). No more lead acid batteries for me.

Xtra POC battery. Met my expectations for use on my POC.

This type batt seems to work well in UPS. Bought few more for other UPSs. Thx.

My testing showed it exceeded advertised capacity at 10.1 Ah with 97% charge efficiency. This battery actually exceeded it’s rated capacity in my tests. I did two full discharge/recharge cycles, and after a full discharge, it took 10.4 amp hours of charge, and after putting those 10.4 amp hours of charge into the battery I was able to pull 10.1 amp hours out. Generally, most batteries are advertised at their “actual”/rated capacity rather than “usable” capacity. For lithium batteries the “usable” capacity is generally only about 80% of the rated/advertised capacity. So I was quite pleased to see that I could pull over 10 amp hours out of this battery without pulling it’s voltage under 11.2 volts. (Dakota Lithium/Clean Republic lists the discharge voltage as being able to go as low as 9.2V, but it’s not good to discharge lithium batteries under 11V generally) For the charge efficiency, see the pictures attached: Putting 10.448 Ah into the battery yields 10.13 Ah out of the battery. 10.13 / 10.448 = 96.95% That’s incredibly efficient. On an SLA battery you’re lucky to hit 80% efficiency and only about 50% of the rated capacity is usable. So while this battery is about 3-4 times more expensive than an SLA of equal “rated” size, this battery is far more efficient, and gives you twice as much “usable” capacity as the equally sized SLA gives you and weighs 1/3 as much. It’s also rated for 2,000 cycles vs the typical 400-500 for an SLA. So over the lifetime of this battery you would need to buy roughly 8 SLA batteries at $25/pop ($200 total) to equal the lifetime usable capacity of this battery at $99.

I put them to a really hard run in my velixor fish flasher and they did really well. Setting them up was easy. I’m going to buy more when the ice firms up.

Muy Bueno!

So far they perform well. Much less voltage drop than 7/8AH SLA while putting out 200W. Installed these in the Razor Dirt Quad and they charge nicely in a 2 series 24V config, on a standard electronic lead acid charger at 2.5A rate. I have a Watts Up monitor installed and will share the Lead acid vs LFP results soon. When I received them they were near full discharge. They both took exactly 120Wh to recharge until the BMS finished the charge cycle. Used for Razor dirt quad testing with Watts Up.

Awesome! I switched out my crappy lead acid batteries that came with my e300s Razor Scooter with a couple Dakota lithiums. I weigh like 245 and it improved my distance traveled from 2 to 5 miles. I was just coasting during mile 5 like “really?”.

3rd set I bought for my 24v ebikes, Way more miles, they work & Charge Great A+
