Lee took the Thai attack apart with the T20 World Cup’s fifth ton and 88 of her 101 runs came from boundaries as the Proteas posted 195 for three, the highest team total in the tournament’s history.
With Sornarrin Tippoch’s debutants slipping to 82 all out, South Africa strengthened their grip on Group B as they face Pakistan on Sunday with the semi-finals in sight.
Thailand have a knack for nabbing early wickets and were gifted one when Dane van Niekerk (2) patted Ratanporn Padunglerd’s full toss to mid-on.
Lee, tenth in the MRF Tyres ICC T20I Batting Rankings, dominated the scoring and slog-swept Onnicha Kamchomphu for a 75-metre six.
Thailand used seven different bowlers inside nine overs but none could withstand Lee’s assault and she reached 50 from 35 balls with a straight six.
Sune Luus, featuring in her fourth Women’s T20 World Cup aged 24, batted on the undercard but still swung Chanida Sutthiruang’s full toss for six over fine leg.
Lee came in without a half-century in nine international innings but glided towards a century in 59 balls, showing her touch with a late cut for four before bringing up a ton fittingly with a four.
No sooner had she raised her bat to salute a jubilant South Africa dugout than she chipped a catch back to Suleeporn Laomi to end the partnership on 131.
Luus ticked to her fourth T20I fifty and Chloe Tryon carted Tippoch over the leg-side fence twice in a penultimate over that cost 20, lifting her side to a record total.
It didn’t take long for Thailand to lose their first wicket as Natthakan Chantam was run out by a fine throw from keeper Trisha Chetty.
Ismail tore the Thai order asunder, beating Nannapat Khoncharoenkai and then Naruemol Chaiwai for sheer pace in successive balls to complete a team hat-trick.
Tippoch and Nattaya Boochatham played out two maidens before a world-class catch from Laura Wolvaardt at midwicket accounted for the Thailand captain.
Kamchomphu led a lone resistance, taking Ayabonga Khaka for back-to-back boundaries and striking Thailand’s first six at the Women’s T20 World Cup off Van Niekerk.
Kamchomphu (26) nicked Luus behind in the 12th over, Chetty whipped off Boochatham’s bails to end her 31-ball vigil and also stumped Wongpaka Liengprasert (6) for the seventh wicket.
Chanida Sutthiruang was given out lbw on review off Nadine de Klerk, Laomi looped a catch to Van Niekerk and Ismail castled Padunglerd to complete a comprehensive win.

There will be two groups of five competing for progress to the semi-finals, with the top two from each group making it through.
The West Indies find themselves in Group B along with England, South Africa, Pakistan and Thailand.
West Indies had a successful tournament in 2018, reaching the semi-finals before being knocked out by the eventual champions Australia. Whilst their form in the format has not been ideal over the last few years, they still have some of the most exciting players in the tournament lining up for them.
Deandra Dottin is among the best attacking batters in the world, particularly if she's facing spin - in the last two years she scores at 8 runs per over against spinners, and only gets out every 38 balls.
With ball in hand, captain Stafanie Taylor will be looking to Shakera Selman to make inroads at the top of the inning - nobody swings the ball more than her over the last two years of T20I cricket, and on the hard fast pitches of Australia, movement through the air will be crucial.
If all goes to plan, West Indies will be more than confident of progressing to the knockout stages.
England made the final in the last edition of the T20 World Cup before, like West Indies, being eliminated by Australia. Heather Knight's side are still somewhat in transition, but a new-found balance relying on Nat Sciver to bowl four overs has allowed them to play an extra specialist batsman - it's given the batting line-up some serious oomph. On the bowling side of things, Sophie Ecclestone is a very important part of the English attack. A tall left-arm orthodox spinner, no player has taken more wickets for England in T20Is since the start of 2018 than Ecclestone, with 35 wickets in that time at an average of 16.82. Offering control as well as attacking threat, she'll be the likely fulcrum of the England attack. Knight will see anything but progress from the group as abject failure, and they'll be eager to go all the way.
Pakistan bowl 76 per cent spin over the last two years - that’s the most of any team in the world during that period. Much like Bangladesh in Group A, this does at least give them a clear blueprint to work to a basic structure they can focus on in the absence of many acclaimed stars. If they have one standout player it's Bismah Maroof, who has notched up 782 T20I runs in the last two years, comfortably the most of any Pakistan batter and the 11th most for anyone in the world. If anyone in Pakistan green is going to spring a shock on the opposition, it'll be her.
In contrast to Pakistan, 76 per cent of the deliveries sent down from South Africa over the last two years, come from pace bowlers, the most of any side in the competition. They were a disappointment at the last T20 World Cup, not reaching the semi-finals. Their bowling is mixed, but their batting is likely to focus around a few key individuals, and one in particular. Alyssa Healy is renowned as an absolute colossus, but Chloe Tryon - at least statistically - is almost keeping pace with her. A powerful left-hander, Tryon is particularly effective against spin bowling, rocketing along at 8.6 runs per over (compared to 7.6 runs per over against seamers). The South African has a particular preference for hitting off spinners, scoring 180 from 113 deliveries against off-break bowlers in T20I cricket. Given how much spin is bowled in T20 cricket, this sets Tryon apart, her strength and power meaning that she doesn’t need pace on the ball to cause damage - South Africa will be looking to her to really lift the scoring rate when she’s at the crease.
Thailand are the most notable presence at this T20 World Cup, an unfamiliar presence in top-level cricket for both men and women. However, much of their success in recent years and in qualification is down to Nattaya Boochatham. A skilful right-arm seamer, Boochatham has taken a lot of wickets since the start of 2018; in fact, in that time period, only Poonam Yadav has taken more international T20 wickets than Boochatham. Undoubtedly, this has been given a boost by the standard of opposition that Thailand have been facing, but it’s been Boochatham who has done the damage in those matches. If Thailand are going to lay a glove on any side at this tournament, she’ll have to be at her best.
