There are other LiPo battery chargers (the kind you would need for your Typhoon H) you can get that can charge 2 batteries at a time, balance the batteries and much more. But whatever you buy remember you also have to purchase Typhoon H compatible battery leads to connect your batteries to your non-Yuneec, third-party charger.
I'm in the USA and so I can't help you much finding a UK-based company to buy a charger from. But let me add this: After I purchased my new LiPo battery charger I spoke with a Yuneec tech about battery chargers in general. I was very reassured by the knowledgeable woman I spoke with that the standard Yuneec charger is perfectly fine for charging and balancing Yuneec batteries. I was told that, after all, the charger was specifically designed for the Yuneec Typhoon H battery. So you may want to consider that before you make a third-party charger purchase. A good third-party charger is probably going to cost you more than purchasing another basic Yuneec battery charger, at least it did for me.
Also, regardless of which charger you use, remember and be vigilant about unplugging the battery once fully charged to avoid damaging it. Overcharging and undercharging can seriously impair battery life and performance.
You may consider searching out any of the forum threads that may already be posted about battery chargers by searching the threads using the search function on the far right top of the forum screen (the magnifying glass icon). Someone else from the UK may have already posted a similar question and you may have an answer waiting for you.
Good luck with your search. And remember LiPo batteries can be unstable, catch fire, and should never be charged without you being present and attentive, regardless of what charger you use. As always, safety first.
