"I have been using them for years there very good for powering my radio equipment chris G0WFH."
"I bought the 22Ah version, to date I too can say it meets my needs. Using FT-991a at 100W. Lightweight, charges from new 4 1/2 hrs. Subsequent charges in about 3 hrs. Not sure what the discharge capacity remaining before recharge. I work in the basis use for 4hrs elapsed time then recharge. G7LJL."
"..the Ultramax is a good buy. A ready-made solution like the Ultramax will be my next purchase if/when I need another portable pack.????."
I bought the 22Ah version a few months ago. I agree it's great for portable use on holiday or the like; perfect for higher power use. Comes highly recommended by me.
"Thank you. Great review of this battery I've had the same battery for nearly 2 years, it had daily heavy use powering my radio kit which pulls a shade over 15A at full power as well as running a Victron Phoenix 12/250W inverter powering a 22-inch PC screen, a 65W type-C powered laptop and 8TB enterprize HDD pulling a shade over 80W when the laptops fully charged.
...I've pushed 15.3V through the T-bar cable using a 30A bench supply with no issues the BMS cuts off the voltage at 15V so every HAM needs one of these."
I've had 2 22a/h versions of this battery for 2 years and I love them, I work portable activating wwff, castles, lighthouses, iota etc and they never let me down !!! M0dxt Bill ????
Many thanks 5 star ????????

Best buy batteries
Battery looks good and have only run one charge/discharge cycle on it so far. Bluetooth app specified will not work with any of my devices - but found another app (Berger) on the app store which gives a top level view of the charge status.
I used to spend 4 pounds on a pack of Duracell and I needed to buy 4 packs per dispenser, Used these C batteries which lasted longer and never looked back.

These lithiums have replaced my sealed lead acid batteries that were pre installed in my Pride Apex Rapid with 17ah battery box. As they were now in series in the box, I bought a 24v 2amp lithium charger with XLR connector.Went for a very long ride for several miles and back. No drop of power on the gauge whatsoever. I think these would fit all the Pride GoGo series with 17/18ah battery box as well. Just make sure you have the T3 terminals as pictured with nuts and bolts. Expensive yes, but these last several times longer than Gel or Lead Acid batteries. Also about a quarter of the weight. I’m sure lithium batteries will come as standard in the not so distant future. Am so pleased I purchased these. Recommend the batteries and BatteryMasters for excellent price and fast next
day delivery.
Ultramax Brand is great value
