Review: On time - Good item and arrived as expected
Review: A compact and easy to use battery with a waterproof rating. - This is a decent LiFePO⁴ battery in a compact waterproof enclosure. The battery has standard f2 terminals and couldn't really be any easier to use. I won't repeat all of the battery specs here, as you can certainly read them on the product page or on the photo I provided of the battery. This battery is currently being used along with a solar panel and MPPT charger to power a wifi enabled cellular modem and low power remote security camera system. I'd almost like to have something critical to say about this battery, but I've had no problems and everything's held up great up to this point. The battery provides more than enough power for the electronics overnight. The battery has just enough capacity at a full charge to keep everything running 24/7 for almost 2½ days without recharge after a heavy snow, which is excellent for my needs. It's a decent battery I think, and I believe it is a good value for the money as a ready to use battery somewhere around $15 to $20. - This is an impartial review of the product listed as "12.8V 7Ah Lithium LiFePO4 Deep Cycle Battery, Built-in 10A BMS 2000+ Cycles Lithium Iron Phosphate Rechargeable Battery for Solar Power" ASIN B0DJM421LW and applies only to this specific product.
