I've been using this battery for 2 months and I am able to play 2, 18 holes rounds on a single charge.
The capacity is 18 AH which is better than the 14AH one it replaced.
The dimensions are exactly the same as the GoKart battery therefore it fits perfectly into the battery carrier of my MK1 GoKart.
"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 ????
