1S LiPo Whoop Chargers
1S LiPo Whoop Chargers
12 products
1S chargers charge single-cell 3.7V LiPo and 3.8V LiHV whoop batteries — the packs with PH2.0, BT2.0, BT3.0 or A30 connectors. This page collects the dedicated whoop chargers in our range: multi-port chargers that top up a full session of packs at once, and compact USB chargers for one or two packs. Check the connector on your packs first, then whether you need an HV mode for LiHV batteries.
How to choose a 1S charger
- Connector: whoop packs use PH2.0, BT2.0, BT3.0 or A30 plugs. Multi-port chargers usually carry two of these; make sure yours is one of them or budget for adapters.
- LiPo vs LiHV: standard cells charge to 4.20V, LiHV to 4.35V. A charger without an HV setting under-charges HV packs by 5–8% of their capacity; one left in HV mode over-charges standard packs.
- Charge current: 0.5–1A per port is typical. A 450mAh pack at 1C takes about an hour; some chargers offer 2A for fast turnaround at the cost of cycle life.
- Storage and discharge: chargers with a storage mode bring packs to 3.8V between sessions, which is the single biggest factor in whoop battery life.
- Power input: USB-C, or a 2S–6S LiPo input for field charging from a larger pack.

Compatibility
A whoop charger cannot charge a 2S or larger pack — those need a balance charger with a JST-XH balance lead, which you will find in our Chargers range. A multi-cell balance charger whose range starts at 1S can also charge a single whoop pack through its main lead with an adapter, one pack per channel. Whoop chargers are safe for any 1S LiPo or LiHV pack regardless of brand, as long as the connector fits and the mode matches the cell chemistry.
Frequently asked questions
- Can I charge 1S whoop batteries with a normal LiPo balance charger?
- Yes, if its range starts at 1S — most current 1–6S chargers do. Charge one pack per channel through the main lead with a PH2.0 or BT2.0 adapter, at the pack's rated charge current. A six-port whoop charger is quicker for a full set.
- Should I use LiHV mode?
- Only for packs marked HV or 3.8V/4.35V. Standard 3.7V LiPo cells must stop at 4.20V; charging them to 4.35V shortens their life and is a fire risk.
- How long does a 6-port whoop charger take?
- At 1A per port, a set of six 450mAh packs charges in about 45–60 minutes. Charging at 0.5A takes twice as long and is gentler on the cells.
