LiOn are good for many reasons, but are expensive, do not like cold weather* and can be easily damaged
Also, depending on the type of cells being used can cause fires if damaged
*All but a few with built in heaters should NOT be charged below about -4C
Life of a lead acid about 4 to 5 years
Life of LiOn about 10 years
A lead acid safe to use down to about 50% charge ( likely to damage below that )
LiOn can be used down to about 10% with total safety
Lead acid does not rely on a BMS
LiOn relies on extra electronics ( in the case in point, built in to the battery I believe )
For me, in a bike application, I cannot warrant the extra cost
I however, could justify the extra cost when fitted to my Commando as it has a much higher CCA starting ability with my electric start kit. I fitted one to the Trident because I could and it is much smaller with a similar/slightly higher capacity.
As and when I get around to designing the electrical system on the Triton I will almost certainly use another Lithium for its smaller dimensions, and not for a need for capacity as it will only run headlights and stop lights. Nowt else. I may consider using a fully sealed battery, but I really want to hide away everything if I can.

In that case just get 3 cells ( something like 18650's ) and you could hide them anywhere ... even inside a frame tube !
Total cost about £9
Depends on how big your ‘relaxation appliance’ is.
A further thought
Given Birds do not charge below 1500 rpm, you get in a traffic jam for more than a few minutes you are gonna end up pushing as the 4Ah will be depleted quite quickly
Realistically you need the 8Ah one at £199
Given the cells are about £3 a go and you would use about 8 maximum ( £23 and a bms ( CIRCA £20 for a good one ) to give you an 8Ah battery, if I WAS looking for a unit I would look else were

That could explain why the battery is giving up
….. mostly 20 mph commute to work !! It’s not charging most of the time
The beign of my life commuting in and out of London……That could explain why the battery is giving up
