Hello Philip, With advancement in battery technology, it is really a good idea to replace the internal SLA. The best will be a 4 cells LiPOFE which will give you an operation voltage of about 13.2v. This will make K2 delivering its full power.
LiPoFe cells are also more stable. On the other hands, a 3 cells LiPo 11.1v is also a possible alternative. The trick is to make sure you get all those cells from reputable battery suppliers. To charge those cells, I would suggest you stick to the intelligent balance chargers which are easily avaliable from the RC shops. 73 Johnny VR2XMC ________________________________ 寄件人︰ PHILIP GRAITCER <[email protected]> 收件人︰ [email protected] 傳送日期︰ 2014年04月24日 (週四) 9:30 AM 主題︰ [Elecraft] Going 2014 with my K2 I love my five year old K2, and although I have a K3, I’d like to keep using the K2 for the field and digital. I’ve noticed that there have been discussions on the two items below on the reflector, but they are years old. Does this list’s collective brain trust have 2014 suggestions? 1. The SLA battery is about worn out, although it has been kept topped up using Don Wilhelm’s suggestion of the AA Engineering charger. I’d like to replace the battery with one that is newer and lighter - LiPO or LiPOFe. Has anyone done this, and can you suggest particular batteries, part numbers, and set up for charging. 2. Digital modes. Don has a nice solution to digital modes on the K2, but are there updates? What are others doing to go digital with their K2s? Thanks, Phil Philip L.
