"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 ????
