ExpertPower 12V 10Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery | 2500-7000 Life Cycles & 10-Year lifetime | Built-in BMS

I purchase this battery with the full expectation that it was gonna be fairly cheaply made, and it is. But it works well for my application... I don't stress it out. So its rated for 5A charging and I only charge it at 2.5A, and its rated for 10A discharge and at most I might discharge it at 4A.So far its operated solidly, but I haven't had it for long. The BMS's low voltage and high voltage cut-off works properly. I dunno if there is a temperature sensor, but I don't use it in an environment where that would matter.-Matt

This battery installed OK into a CyberPower 1500VA PCS Sinewave UPS. But when a small power blip occurred; all my lead acid UPS systems had no problem but the CyberPower 1500 shut off. I think this was because the UPS thought the battery was charged and even indicated with a 300W load that it had 32 minutes run time. But it was wrong. The load was shut off and the UPS shut itself off. I'm not disparaging either this battery or this UPS. Just, they don't work together most likely because an SLA charger will not charge this battery. See the answer to the first question for more detail.

Bought in July of 21, dead in Aug of 23 for a ride on, along with an lifepo4 charger. Kept charged when not in use. Didn't do anywhere near the claimed 7500 cycles. Do not recommend.

My aging Celestron power tank used to drive my night-time 'scopes was flagging. Too much extended use maybe, maybe casual maintenance, but all the same the old tank was now a puddle.Pros: LiFePo4 batts run until they collapse, providing juice well beyond the 50% lead-acid batts.This was a direct replacement size-wise, with a 30% boost in sustained amps. Make sure you measure the bay intending to receive this new batt.LiFePo4 batts provide up to 80% energy, but then they quit suddenly.LifePo4 batts charge rapidly, and far more often than their lead-acid counterparts.This batt is considerably LIGHTER in weight making it easier to cart around in the dark.Note: LiFePo4 batts require a compatible charger, I use this from Amazon:I have several of these Mroinge LifePo4/Lead acid 2A chargeing and love 'em as they work for nearly any batt:https://www.amazon.com/gp/product/B07MCTXFC7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Cons: They are pricey, but taken in the long haul are a better value for service and overall lifetime.So for my night-time astronomy habits that extend into the wee hours, this was a great upgrade.

Slightly below rated capacity (2.5% less at 125 Wh). Charged using CC/CV up to 14.4V, no more than 2A during CC, and at the end of charging it was drawing just a few mA as expected. Let sit for a day. Resting OC voltage was 13.85V. Ran test at 0.15C rate using an Ohmite shunt and voltage measured at the battery terminals (not at the load!). Stopped when voltage dropped to 10V. 125Ah result. Can't complain too much about that, but most batteries I buy these days test at slightly over the rated capacity.

The best advice anyone can offer is, know the application and purpose you are purchasing a battery. I bought this for a lightweight use. I wired it using the existing positive and negative poles. Then added a disconnect section to the wired power circuit plug for my charger to attach to the battery. When needing a charge. Works great, with a respectable amp hour for its size. I mounted it with a hook and latch Velcro to the bottom of my carbon fiber panel.

This was a replacement purchase of the smaller amps. The original lasted 5 years .

Works great for my Garmin Striker
